It has been estimated that half of the world's oxygen is produced by phytoplankton. About 45 percent of the sea's primary production of living material
5775-517: Is "sea". The law of the sea has at its center the definition of the boundaries of the ocean, clarifying its application in marginal seas . But what bodies of water other than the sea the law applies to is being crucially negotiated in the case of the Caspian Sea and its status as "sea", basically revolving around the issue of the Caspian Sea about either being factually an oceanic sea or only
6006-604: Is a calque of the Latin name, from μέσος ( mésos , "in the middle") and γήινος ( gḗinos , "of the earth"), from γῆ ( gê , "land, earth"). The original meaning may have been 'the sea in the middle of the earth', rather than 'the sea enclosed by land'. Ancient Iranians called it the "Roman Sea", and in Classical Persian texts , it was called Daryāy-e Rōm (دریای روم), which may be from Middle Persian form, Zrēh ī Hrōm (𐭦𐭫𐭩𐭤 𐭩 𐭤𐭫𐭥𐭬).

Despite this, Syria remains a one-party state with an extensive secret police apparatus that curtails any independent political activity. The new constitution introduced single-handedly by the Assad regime , without participation of the Syrian opposition , has bolstered its authoritarian character by bestowing extraordinary powers on
6468-449: Is a continuous circulation of water in the oceans. Warm surface currents cool as they move away from the tropics, and the water becomes denser and sinks. The cold water moves back towards the equator as a deep sea current, driven by changes in the temperature and density of the water, before eventually welling up again towards the surface. Deep seawater has a temperature between −2 °C (28 °F) and 5 °C (41 °F) in all parts of

The indentation of a coastline, especially between two headlands, is a bay , a small bay with a narrow inlet is a cove and a large bay may be referred to as a gulf . Coastlines are influenced by several factors including the strength of the waves arriving on the shore, the gradient of the land margin,
6930-487: Is an upwelling of cold waters, and also near estuaries where land-sourced nutrients are present, plant growth is higher. This means that the most productive areas, rich in plankton and therefore also in fish, are mainly coastal. There is a broader spectrum of higher animal taxa in the sea than on land, many marine species have yet to be discovered and the number known to science is expanding annually. Some vertebrates such as seabirds , seals and sea turtles return to

The zone where land meets sea is known as the coast and the part between the lowest spring tides and the upper limit reached by splashing waves is the shore . A beach is the accumulation of sand or shingle on the shore. A headland
8778-534: Is often rich in nutrients and creates blooms of phytoplankton and a great increase in the productivity of the sea. Tides are the regular rise and fall in water level experienced by seas and oceans in response to the gravitational influences of the Moon and the Sun, and the effects of the Earth's rotation. During each tidal cycle, at any given place the water rises to a maximum height known as "high tide" before ebbing away again to

The top of a wave is known as the crest, the lowest point between waves is the trough and the distance between the crests is the wavelength. The wave is pushed across the surface of the sea by the wind, but this represents a transfer of energy and not a horizontal movement of water. As waves approach land and move into shallow water , they change their behaviour. If approaching at an angle, waves may bend ( refraction ) or wrap rocks and headlands ( diffraction ). When

17325-412: The swash moves beach material seawards. Under their influence, the sand and shingle on the beach is ground together and abraded. Around high tide, the power of a storm wave impacting on the foot of a cliff has a shattering effect as air in cracks and crevices is compressed and then expands rapidly with release of pressure. At the same time, sand and pebbles have an erosive effect as they are thrown against
17556-420: The water , carbon , and nitrogen cycles . The surface of water interacts with the atmosphere, exchanging properties such as particles and temperature, as well as currents . Surface currents are the water currents that are produced by the atmosphere's currents and its winds blowing over the surface of the water, producing wind waves , setting up through drag slow but stable circulations of water, as in
17787-517: The "Syrian Sea". In ancient Syrian texts, Phoenician epics and in the Hebrew Bible , it was primarily known as the "Great Sea", הים הגדול HaYam HaGadol , ( Numbers ; Book of Joshua ; Ezekiel ) or simply as "The Sea" ( 1 Kings ). However, it has also been called the "Hinder Sea" because of its location on the west coast of the region of Syria or the Holy Land (and therefore behind a person facing
18018-556: The "northwest of the Arabian plate ". Petroleum in commercial quantities was first discovered in the northeast in 1956. The most important oil fields are those of al-Suwaydiyah , Karatchok , Rmelan near al-Hasakah , as well as al-Omar and al-Taym fields near Dayr az–Zawr . The fields are a natural extension of the Iraqi fields of Mosul and Kirkuk . Petroleum became Syria's leading natural resource and chief export after 1974. Natural gas
18249-589: The 13th century BC, founding city states such as Amrit , Simyra , Arwad , Paltos , Ramitha , and Shuksi . From these coastal regions, they eventually spread their influence throughout the Mediterranean , including building colonies in Malta , Sicily, the Iberian peninsula (modern Spain and Portugal ), and the coasts of North Africa and most significantly, founding the major city-state of Carthage (in modern Tunisia ) in
18480-491: The 2024 Fragile States Index , Syria is one of the most dangerous places for journalists . Freedom of press is extremely limited, and the country is ranked 2nd worst in the 2024 World Press Freedom Index . It is the most corrupt country in the MENA region and was ranked the 2nd lowest globally on the 2023 Corruption Perceptions Index . Syria has also become the epicentre of a state-sponsored multi-billion dollar illicit drug cartel ,
18711-481: The 2024 Global Peace Index and 4th worst in the 2024 Fragile States Index , Syria is one of the most dangerous places for journalists . Freedom of press is extremely limited, and the country is ranked 2nd worst in the 2024 World Press Freedom Index . Syria is the most corrupt country in the Middle East and was ranked the 2nd lowest globally on the 2023 Corruption Perceptions Index . The country has also become
18942-461: The 2nd and 3rd centuries (AD). Syrians held considerable power during the Severan dynasty . The matriarch of the family and Empress of Rome as wife of emperor Septimius Severus was Julia Domna , a Syrian from the city of Emesa (modern day Homs ), whose family held hereditary rights to the priesthood of the god El-Gabal . Her great nephews, also Arabs from Syria, would also become Roman Emperors,
19173-507: The 7th and 8th centuries AD, and was to be a vehicle for the spread of Christianity. The Assyrians named their colonies of Syria and Lebanon Eber-Nari . Assyrian domination ended after the Assyrians greatly weakened themselves in a series of brutal internal civil wars, followed by attacks from: the Medes , Babylonians , Chaldeans , Persians , Scythians and Cimmerians . During the fall of Assyria,
19404-515: The 7th century, and with it the religion of Islam , which soon swept across from the east; at its greatest extent, the Arabs, under the Umayyads , controlled most of the Mediterranean region and left a lasting footprint on its eastern and southern shores. A variety of foodstuffs, spices and crops were introduced to the western Mediterranean's Spain and Sicily during Arab rule, via the commercial networks of
19635-540: The 8th century BC Çineköy inscription . The area designated by the word has changed over time. Classically, Syria lies at the eastern end of the Mediterranean, between Arabia to the south and Asia Minor to the north, stretching inland to include parts of Iraq, and having an uncertain border to the northeast that Pliny the Elder describes as including, from west to east, Commagene , Sophene , and Adiabene . By Pliny's time, however, this larger Syria had been divided into
19866-516: The 9th century BC, which was much later to become the center of a major empire, rivaling the Roman Republic . Syria and the Western half of Near East then fell to the vast Neo Assyrian Empire (911 BC – 605 BC). The Assyrians introduced Imperial Aramaic as the lingua franca of their empire. This language was to remain dominant in Syria and the entire Near East until after the Islamic conquest in
20097-554: The Austronesian " Lapita " peoples displayed great feats of navigation, reaching out from the Bismarck Archipelago to as far away as Fiji , Tonga , and Samoa . Their descendants continued to travel thousands of miles between tiny islands on outrigger canoes , and in the process they found many new islands, including Hawaii , Easter Island (Rapa Nui), and New Zealand. The Ancient Egyptians and Phoenicians explored
20328-786: The Ayyubids." After a century of Seljuk rule, Syria was largely conquered (1175–1185) by the Kurdish liberator Salah ad-Din , founder of the Ayyubid dynasty of Egypt. Aleppo fell to the Mongols of Hulegu in January 1260, and Damascus in March, but then Hulegu was forced to break off his attack to return to China to deal with a succession dispute. A few months later, the Mamluks arrived with an army from Egypt and defeated
20559-464: The Ba'ath party apparatus; after the purging of traditional civilian and military elites by the new regime. The 1963 Ba'athist coup marked a "radical break" in modern Syrian history , after which Ba'ath party monopolised power in the country to establish a one-party state and shaped a new socio-political order by enforcing its state ideology . On 23 February 1966, the neo-Ba'athist Military Committee carried out an intra-party rebellion against
20790-409: The Ba'athist Old Guard ( Aflaq and Bitar ), imprisoned President Amin al-Hafiz and designated a regionalist, civilian Ba'ath government on 1 March. Although Nureddin al-Atassi became the formal head of state, Salah Jadid was Syria's effective ruler from 1966 until November 1970, when he was deposed by Hafiz al-Assad , who at the time was Minister of Defense. The coup led to the schism within
21021-405: The Earth , clarified the process of sedimentation , and assisted the study of volcanism and earthquakes . A characteristic of seawater is that it is salty. Salinity is usually measured in parts per thousand ( ‰ or per mil), and the open ocean has about 35 grams (1.2 oz) solids per litre, a salinity of 35 ‰. The Mediterranean Sea is slightly higher at 38 ‰, while the salinity of
21252-420: The Earth is closest to the Moon because it is also where the effect of the Moon's gravity is stronger. On the opposite side of the Earth, the lunar force is at its weakest and this causes another bulge to form. As the Moon rotates around the Earth, so do these ocean bulges move around the Earth. The gravitational attraction of the Sun is also working on the seas, but its effect on tides is less powerful than that of
21483-411: The Earth to make a complete revolution and return the Moon to its previous position relative to an observer. The Moon's mass is some 27 million times smaller than the Sun, but it is 400 times closer to the Earth. Tidal force or tide-raising force decreases rapidly with distance, so the moon has more than twice as great an effect on tides as the Sun. A bulge is formed in the ocean at the place where
21714-596: The Eblaite language have shown that it was an East Semitic language , closely related to the Akkadian language . Ebla was weakened by a long war with Mari , and the whole of Syria became part of the Mesopotamian Akkadian Empire after Sargon of Akkad and his grandson Naram-Sin 's conquests ended Eblan domination over Syria in the first half of the 23rd century BC. By the 21st century BC, Hurrians settled in
21945-527: The Empire and overran Ottoman Syria , capturing Damascus. His short-term rule over the domain attempted to change the demographics and social structure of the region: he brought thousands of Egyptian villagers to populate the plains of Southern Syria , rebuilt Jaffa and settled it with veteran Egyptian soldiers aiming to turn it into a regional capital, and he crushed peasant and Druze rebellions and deported non-loyal tribesmen. By 1840, however, he had to surrender
22176-467: The French, notably the Battle of al-Kafr on 21 July 1925, the Battle of al-Mazraa on 2–3 August 1925, and the battles of Salkhad, al-Musayfirah and Suwayda. France sent thousands of troops from Morocco and Senegal, leading the French to regain many cities, although resistance lasted until the spring of 1927. The French sentenced Sultan al-Atrash to death, but he had escaped with the rebels to Transjordan and
22407-630: The Islamic world. These include sugarcane, rice, cotton, alfalfa, oranges, lemons, apricots,spinach, eggplants, carrots, saffron and bananas. The Arabs also continued extensive cultivation and production of olive oil (the Spanish words for 'oil' and 'olive'— aceite and aceituna , respectively—are derived from the Arabic al-zait , meaning 'olive juice'), and pomegranates (the heraldic symbol of Granada) from classical Greco-Roman times. The Arab invasions disrupted
22638-581: The Levant, being the only state in history to ever do so, being given the nickname "Roman Lake". The Western Roman Empire collapsed around 476 AD. The east was again dominant as Roman power lived on in the Byzantine Empire formed in the 4th century from the eastern half of the Roman Empire . Though the Eastern Roman Empire would continue to hold almost all of the Mediterranean, another power arose in
22869-594: The Mediterranean Sea (from west to east): Sea A sea is a large body of salt water . There are particular seas and the sea . The sea commonly refers to the Ocean , the interconnected body of seawaters that spans most of Earth. Particular seas are either marginal seas , second-order sections of the oceanic sea (e.g. the Mediterranean Sea ), or certain large, nearly landlocked bodies of water. The salinity of water bodies varies widely, being lower near
23100-762: The Mediterranean Sea is the Nile , which takes its sources in equatorial Africa. The basin of the Nile constitutes about two-thirds of the Mediterranean drainage basin and encompasses areas as high as the Ruwenzori Mountains . Among other important rivers in Africa, are the Moulouya and the Chelif , both on the north side of the Atlas Mountains . In Asia, are the Ceyhan and Seyhan , both on
23331-440: The Mediterranean during World War I and Mediterranean theatre of World War II . With the opening of the lockless Suez Canal in 1869, the flow of trade between Europe and Asia changed fundamentally. The fastest route now led through the Mediterranean towards East Africa and Asia. This led to a preference for the Mediterranean countries and their ports like Trieste with direct connections to Central and Eastern Europe experienced
23562-478: The Mediterranean include: The Alpine arc , which also has a great meteorological impact on the Mediterranean area, touches the Mediterranean in the west in the area around Nice . The typical Mediterranean climate has hot, dry summers and mild, rainy winters. Crops of the region include olives , grapes , oranges , tangerines , carobs and cork . The Mediterranean Sea includes 15 marginal seas : Note 1: The International Hydrographic Organization defines
23793-564: The Middle Assyrian Empire, who also annexed much of the west during the reign of Tiglath-Pileser I 1114–1076 BC. With the destruction of the Hittites and the decline of Assyria in the late 11th century BC, the Aramean tribes gained control of much of the interior, founding states such as Bit Bahiani , Aram-Damascus , Hamath , Aram-Rehob , Aram-Naharaim , and Luhuti . From this point, the region became known as Aramea or Aram . There
24024-551: The Mongols in the Battle of Ain Jalut in Galilee . The Mamluk leader, Baibars , made Damascus a provincial capital. When he died, power was taken by Qalawun . In the meantime, an emir named Sunqur al-Ashqar had tried to declare himself ruler of Damascus, but he was defeated by Qalawun on 21 June 1280, and fled to northern Syria. Al-Ashqar, who had married a Mongol woman, appealed for help from
24255-765: The Mongols. The Mongols of the Ilkhanate took Aleppo in October 1280, but Qalawun persuaded Al-Ashqar to join him, and they fought against the Mongols on 29 October 1281, in the Second Battle of Homs , which was won by the Mamluks . In 1400, the Muslim Turco-Mongol conqueror Tamurlane invaded Syria, in which he sacked Aleppo , and captured Damascus after defeating the Mamluk army. The city's inhabitants were massacred, except for
24486-413: The Moon, and when the Sun, Moon and Earth are all aligned (full moon and new moon), the combined effect results in the high "spring tides". In contrast, when the Sun is at 90° from the Moon as viewed from Earth, the combined gravitational effect on tides is less causing the lower "neap tides". A storm surge can occur when high winds pile water up against the coast in a shallow area and this, coupled with
24717-776: The Orient, it however continued. Europe started to revive, however, as more organized and centralized states began to form in the later Middle Ages after the Renaissance of the 12th century . Ottoman power based in Anatolia continued to grow, and in 1453 extinguished the Byzantine Empire with the Conquest of Constantinople . Ottomans gained control of much of the eastern part sea in the 16th century and also maintained naval bases in southern France (1543–1544), Algeria and Tunisia. Barbarossa ,
24948-656: The Ottoman captain is a symbol of this domination with the victory of the Battle of Preveza (1538). The Battle of Djerba (1560) marked the apex of Ottoman naval domination in the eastern Mediterranean. As the naval prowess of the European powers increased, they confronted Ottoman expansion in the region when the Battle of Lepanto (1571) checked the power of the Ottoman Navy . This was the last naval battle to be fought primarily between galleys . The Barbary pirates of Northwest Africa preyed on Christian shipping and coastlines in
25179-549: The Southern Hemisphere in the Roaring Forties , long, organised masses of water called swell roll across the ocean. If the wind dies down, the wave formation is reduced, but already-formed waves continue to travel in their original direction until they meet land. The size of the waves depends on the fetch , the distance that the wind has blown over the water and the strength and duration of that wind. When waves meet others coming from different directions, interference between
25410-604: The Spanish Magellan-Elcano expedition which would be the first to sail around the world. Syria Syria , officially the Syrian Arab Republic , is a country in West Asia located in the Eastern Mediterranean and the Levant . It is bounded by the Mediterranean Sea to the west, Turkey to the north, Iraq to the east and southeast , Jordan to the south , and Israel and Lebanon to
25641-520: The Syrian Army. The insurgents unified under the banner of the Free Syrian Army and fought in an increasingly organized fashion; however, the civilian component of the armed opposition lacked an organized leadership. The uprising has sectarian undertones, though neither faction in the conflict has described sectarianism as playing a major role. The opposition is dominated by Sunni Muslims, whereas
25872-451: The Syrian government, 9,815–10,146 people, including 3,430 members of the security forces, 2,805–3,140 insurgents and up to 3,600 civilians, have been killed in fighting with what they characterize as "armed terrorist groups." To escape the violence, tens of thousands of Syrian refugees have fled the country to neighboring Jordan , Iraq and Lebanon , as well to Turkey . The total official UN numbers of Syrian refugees reached 42,000 at
26103-587: The Western Mediterranean Sea. According to Robert Davis, from the 16th to 19th centuries, pirates captured 1 million to 1.25 million Europeans as slaves. The development of oceanic shipping began to affect the entire Mediterranean. Once, most of the trade between Western Europe and the East was passing through the region , but after the 1490s the development of a sea route to the Indian Ocean allowed
26334-517: The added CO 2 is absorbed by the oceans, forming carbonic acid and lowering the pH (now below 8.1 ) through a process called ocean acidification . The extent of further ocean chemistry changes, including ocean pH, will depend on climate change mitigation efforts taken by nations and their governments. The amount of oxygen found in seawater depends primarily on the plants growing in it. These are mainly algae, including phytoplankton , with some vascular plants such as seagrasses . In daylight,
26565-619: The ages. The earliest advanced civilizations in the Mediterranean were the Egyptians and the Minoans , who traded extensively with each other. Other notable civilizations that appeared somewhat later are the Hittites and other Anatolian peoples , the Phoenicians , and Mycenean Greece . Around 1200 BC the eastern Mediterranean was greatly affected by the Bronze Age Collapse , which resulted in
26796-561: The area as generic Mediterranean Sea, in the Western Basin. It does not recognize the label Sea of Sardinia . Note 2: Thracian Sea and Myrtoan Sea are seas that are part of the Aegean Sea . Note 3: The Black Sea is not considered part of it. The International Hydrographic Organization defines the limits of the Mediterranean Sea as follows: Stretching from the Strait of Gibraltar in
27027-517: The area back to the Ottomans. From 1864, Tanzimat reforms were applied on Ottoman Syria, carving out the provinces (vilayets) of Aleppo , Zor , Beirut and Damascus Vilayet ; Mutasarrifate of Mount Lebanon was created, as well, and soon after the Mutasarrifate of Jerusalem was given a separate status. During World War I , the Ottoman Empire entered the conflict on the side of Germany and
27258-635: The artisans, who were deported to Samarkand . Tamurlane also conducted specific massacres of the Aramean and Assyrian Christian populations, greatly reducing their numbers. By the end of the 15th century, the discovery of a sea route from Europe to the Far East ended the need for an overland trade route through Syria. In 1516, the Ottoman Empire invaded the Mamluk Sultanate of Egypt , conquering Syria, and incorporating it into its empire. The Ottoman system
27489-412: The behaviour of elements and molecules within the oceans: particularly, at the moment, the ocean's role in the carbon cycle and carbon dioxide 's role in the increasing acidification of seawater. Marine and maritime geography charts the shape and shaping of the sea, while marine geology (geological oceanography) has provided evidence of continental drift and the composition and structure of
27720-529: The bottom of the ocean provides food for an assembly of organisms which similarly rely largely on the actions of sulphur-reducing bacteria. Such places support unique biomes where many new microbes and other lifeforms have been discovered. Humans have navigated the seas since they first built sea-going craft. Mesopotamians were using bitumen to caulk their reed boats and, a little later, masted sails . By c. 3000 BC, Austronesians on Taiwan had begun spreading into maritime Southeast Asia . Subsequently,
27951-460: The boundaries between the land and sea, the slightly denser oceanic plates slide beneath the continental plates and more subduction trenches are formed. As they grate together, the continental plates are deformed and buckle causing mountain building and seismic activity. The Earth's deepest trench is the Mariana Trench which extends for about 2,500 kilometres (1,600 miles) across the seabed. It
28182-826: The capital of empire to Baghdad . Arabic – made official under Umayyad rule – became the dominant language, replacing Greek and Aramaic of the Byzantine era. In 887, the Egypt-based Tulunids annexed Syria from the Abbasids, and were later replaced by once the Egypt-based Ikhshidids and still later by the Hamdanids originating in Aleppo founded by Sayf al-Dawla . Sections of Syria were held by French, English, Italian and German overlords between 1098 and 1189 AD during
28413-509: The case of the ocean sustaining deep-sea ocean currents . Deep-sea currents, known together as the global conveyor belt , carry cold water from near the poles to every ocean and significantly influence Earth's climate. Tides , the generally twice-daily rise and fall of sea levels , are caused by Earth's rotation and the gravitational effects of the Moon and, to a lesser extent, of the Sun . Tides may have
28644-825: The city one of the richest in the Roman empire. Eventually, in the late 3rd century AD, the Palmyrene king Odaenathus defeated the Persian emperor Shapur I and controlled the entirety of the Roman East while his successor and widow Zenobia established the Palmyrene Empire , which briefly conquered Egypt, Syria, Palestine, much of Asia Minor, Judah and Lebanon, before being finally brought under Roman control in 273 AD. The northern Mesopotamian Assyrian kingdom of Adiabene controlled areas of north east Syria between 10 AD and 117 AD, before it
28875-890: The city, most of which were halted after his death. Syria is significant in the history of Christianity ; Saulus of Tarsus, better known as the Apostle Paul , was converted on the Road to Damascus and emerged as a significant figure in the Christian Church at Antioch in ancient Syria. Muhammad 's first interaction with the people of Syria was during the Invasion of Dumatul Jandal in July 626 where he ordered his followers to invade Duma, because Muhammad received intelligence that some tribes there were involved in highway robbery and preparing to attack Medina itself. William Montgomery Watt claims that this
29106-437: The coast scour out channels and transport sand and pebbles away from their place of origin. Sediment carried to the sea by rivers settles on the seabed causing deltas to form in estuaries. All these materials move back and forth under the influence of waves, tides and currents. Dredging removes material and deepens channels but may have unexpected effects elsewhere on the coastline. Governments make efforts to prevent flooding of
29337-446: The composition and hardness of the coastal rock, the inclination of the off-shore slope and the changes of the level of the land due to local uplift or submergence. Normally, waves roll towards the shore at the rate of six to eight per minute and these are known as constructive waves as they tend to move material up the beach and have little erosive effect. Storm waves arrive on shore in rapid succession and are known as destructive waves as
29568-415: The conflict appears to have settled into a frozen state. Although roughly 30% of the country is controlled by opposition forces, heavy fighting has largely ceased and there is a growing regional trend toward normalizing relations with the regime of Bashar al-Assad. Syria lies between latitudes 32° and 38° N , and longitudes 35° and 43° E . The climate varies from the humid Mediterranean coast, through
29799-598: The continental shelf. Alternatively, marine habitats can be divided vertically into pelagic (open water), demersal (just above the seabed) and benthic (sea bottom) habitats. A third division is by latitude : from polar seas with ice shelves, sea ice and icebergs, to temperate and tropical waters. Coral reefs, the so-called "rainforests of the sea", occupy less than 0.1 percent of the world's ocean surface, yet their ecosystems include 25 percent of all marine species. The best-known are tropical coral reefs such as Australia's Great Barrier Reef , but cold water reefs harbour
30030-417: The control of Vichy France until the British and Free French occupied the country in the Syria-Lebanon campaign in July 1941. Continuing pressure from Syrian nationalists and the British forced the French to evacuate their troops in April 1946, leaving the country in the hands of a republican government that had been formed during the mandate. Upheaval dominated Syrian politics from independence through
30261-407: The country in 2014-2015, leading to a refugee crisis where more than 6 million refugees left the country. A large coalition was launched against ISIS and ISIS was defeated. Three political entities – the Syrian Interim Government , Syrian Salvation Government , and Rojava – have emerged in Syrian territory to challenge Assad's rule. A country of fertile plains, high mountains, and deserts, Syria
30492-522: The currents. Most of the smallest organisms are the larvae of fish and marine invertebrates which liberate eggs in vast numbers because the chance of any one embryo surviving to maturity is so minute. The zooplankton feed on phytoplankton and on each other and form a basic part of the complex food chain that extends through variously sized fish and other nektonic organisms to large squid , sharks , porpoises , dolphins and whales . Some marine creatures make large migrations, either to other regions of
30723-526: The deepest recorded point is 5,109 ± 1 m (16,762 ± 3 ft) in the Calypso Deep in the Ionian Sea . It lies between latitudes 30° and 46° N and longitudes 6° W and 36° E . Its west–east length, from the Strait of Gibraltar to the Gulf of Alexandretta , on the southeastern coast of Turkey , is about 4,000 kilometres (2,500 mi). The north–south length varies greatly between different shorelines and whether only straight routes are considered. Also including longitudinal changes,
30954-410: The destruction may be caused by the flood water draining back into the sea after the tsunami has struck, dragging debris and people with it. Often several tsunami are caused by a single geological event and arrive at intervals of between eight minutes and two hours. The first wave to arrive on shore may not be the biggest or most destructive. Wind blowing over the surface of the sea causes friction at
31185-511: The destruction of many cities and trade routes. The most notable Mediterranean civilizations in classical antiquity were the Greek city states and the Phoenicians , both of which extensively colonized the coastlines of the Mediterranean. Darius I of Persia , who conquered Ancient Egypt, built a canal linking the Red Sea to the Nile, and thus the Mediterranean. Darius's canal was wide enough for two triremes to pass each other with oars extended and required four days to traverse. Following
31416-413: The direction of the wind. The friction between air and water caused by a gentle breeze on a pond causes ripples to form. A strong blow over the ocean causes larger waves as the moving air pushes against the raised ridges of water. The waves reach their maximum height when the rate at which they are travelling nearly matches the speed of the wind. In open water, when the wind blows continuously as happens in
31647-417: The early fifteenth century, sailing the Indian and Pacific Oceans. In the late fifteenth century, Western European mariners started making longer voyages of exploration in search of trade. Bartolomeu Dias rounded the Cape of Good Hope in 1487 and Vasco da Gama reached India via the Cape in 1498. Christopher Columbus sailed from Cadiz in 1492, attempting to reach the eastern lands of India and Japan by
31878-418: The east), which is sometimes translated as "Western Sea". Another name was the "Sea of the Philistines ", ( Book of Exodus ), from the people inhabiting a large portion of its shores near the Israelites . In Modern Hebrew , it is called הים התיכון HaYam HaTikhon 'the Middle Sea'. In Classic Persian texts was called Daryāy-e Šām (دریای شام) "The Western Sea" or "Syrian Sea". In Modern Standard Arabic , it
32109-418: The east, and the West Semitic speaking Arameans who subsumed the earlier Amorites. They too were subjugated by Assyria and the Hittites for centuries. The Egyptians fought the Hittites for control over western Syria; the fighting reached its zenith in 1274 BC with the Battle of Kadesh . The west remained part of the Hittite empire until its destruction c. 1200 BC, while eastern Syria largely became part of
32340-513: The epicentre of a state-sponsored multi-billion dollar illicit drug cartel , the largest in the world. The civil war has resulted in more than 600,000 deaths, with pro-Assad forces causing more than 90% of the total civilian casualties . The war led to a massive refugee crisis , with an estimated 7.6 million internally displaced people (July 2015 UNHCR figure) and over 5 million refugees (July 2017 registered by UNHCR ). The war has also worsened economic conditions, with more than 90% of
32571-422: The first being Elagabalus and the second, his cousin Alexander Severus . Another Roman emperor who was a Syrian was Philip the Arab (Marcus Julius Philippus), who was born in Roman Arabia . He was emperor from 244 to 249, and ruled briefly during the Crisis of the Third Century . During his reign, he focused on his home town of Philippopolis (modern day Shahba ) and began many construction projects to improve
32802-413: The flourishing of trade between Europe and the outremer region. Genoa, Venice and Pisa created colonies in regions controlled by the Crusaders and came to control the trade with the Orient. These colonies also allowed them to trade with the Eastern world. Though the fall of the Crusader states and attempts at banning of trade relations with Muslim states by the Popes temporarily disrupted the trade with
33033-422: The food chain or precipitated into the deeper, more carbon-rich layers as dead soft tissue or in shells and bones as calcium carbonate . It circulates in this layer for long periods of time before either being deposited as sediment or being returned to surface waters through thermohaline circulation. The oceans are home to a diverse collection of life forms that use it as a habitat. Since sunlight illuminates only
33264-408: The gap and a circular movement of surface currents known as a gyre is formed. There are five main gyres in the world's oceans: two in the Pacific, two in the Atlantic and one in the Indian Ocean. Other smaller gyres are found in lesser seas and a single gyre flows around Antarctica . These gyres have followed the same routes for millennia, guided by the topography of the land, the wind direction and
33495-541: The global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar —the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa —is only 14 km (9 mi) wide. The Mediterranean Sea encompasses a vast number of islands , some of them of volcanic origin. The two largest islands, in both area and population, are Sicily and Sardinia . The Mediterranean Sea has an average depth of 1,500 m (4,900 ft) and
33726-570: The globe. Seawater with a typical salinity of 35 ‰ has a freezing point of about −1.8 °C (28.8 °F). When its temperature becomes low enough, ice crystals form on the surface. These break into small pieces and coalesce into flat discs that form a thick suspension known as frazil . In calm conditions, this freezes into a thin flat sheet known as nilas , which thickens as new ice forms on its underside. In more turbulent seas, frazil crystals join into flat discs known as pancakes. These slide under each other and coalesce to form floes . In
33957-597: The government and Shabiha of using civilians as human shields when they advanced on opposition held-areas. Anti-government rebels have been accused of human rights abuses as well, including torture, kidnapping, unlawful detention and execution of civilians, Shabiha and soldiers. HRW also expressed concern at the kidnapping of Iranian nationals. The UN Commission of Inquiry has also documented abuses of this nature in its February 2012 report, which also includes documentation that indicates rebel forces have been responsible for displacement of civilians. Being ranked 8th last on
34188-503: The government's response to the crisis, but sent an observer mission in December 2011, as part of its proposal for peaceful resolution of the crisis. The latest attempts to resolve the crisis has been made through the appointment of Kofi Annan, as a special envoy to resolve the Syrian crisis in the Middle East. Some analysts however have posited the partitioning the region into a Sunnite east, Kurdish north and Shiite / Alawite west. Twelve years into Syria's devastating civil war,
34419-436: The immediate coastline on all sides of the Mediterranean tends to have strong maritime moderation. The sea was an important route for merchants and travellers of ancient times, facilitating trade and cultural exchange between the peoples of the region. The history of the Mediterranean region is crucial to understanding the origins and development of many modern societies. The Roman Empire maintained nautical hegemony over
34650-437: The importation of Asian spices and other goods through the Atlantic ports of western Europe. The sea remained strategically important. British mastery of Gibraltar ensured their influence in Africa and Southwest Asia. Especially after the naval battles of Abukir (1799, Battle of the Nile ) and Trafalgar (1805), the British had for a long time strengthened their dominance in the Mediterranean. Wars included Naval warfare in
34881-442: The interface between air and sea. Not only does this cause waves to form, but it also makes the surface seawater move in the same direction as the wind. Although winds are variable, in any one place they predominantly blow from a single direction and thus a surface current can be formed. Westerly winds are most frequent in the mid-latitudes while easterlies dominate the tropics. When water moves in this way, other water flows in to fill
35112-421: The land by the building of breakwaters , seawalls , dykes and levees and other sea defences. For instance, the Thames Barrier is designed to protect London from a storm surge, while the failure of the dykes and levees around New Orleans during Hurricane Katrina created a humanitarian crisis in the United States. The sea plays a part in the water or hydrological cycle , in which water evaporates from
35343-523: The land to breed but fish, cetaceans and sea snakes have a completely aquatic lifestyle and many invertebrate phyla are entirely marine. In fact, the oceans teem with life and provide many varying microhabitats. One of these is the surface film which, even though tossed about by the movement of waves, provides a rich environment and is home to bacteria, fungi , microalgae , protozoa , fish eggs and various larvae. The pelagic zone contains macro- and microfauna and myriad zooplankton which drift with
35574-402: The large number of migrants who drowned there after their boats capsized. European Parliament president Martin Schulz said in 2014 that Europe's migration policy "turned the Mediterranean into a graveyard", referring to the number of drowned refugees in the region as a direct result of the policies. An Azerbaijani official described the sea as "a burial ground ... where people die". Following
35805-411: The largest in the world. Several sources indicate that the name Syria is derived from the 8th century BC Luwian term "Sura/i", and the derivative ancient Greek name: Σύριοι , Sýrioi , or Σύροι , Sýroi , both of which originally derived from Aššūr ( Assyria ) in northern Mesopotamia (present-day Iraq). However, from the Seleucid Empire (323–150 BC), this term was also applied to
36036-461: The late 1960s. In May 1948, Syrian forces invaded Palestine , together with other Arab states, and immediately attacked Jewish settlements. Their president Shukri al-Quwwatli instructed his troops in the front, "to destroy the Zionists". The Invasion purpose was to prevent the establishment of the State of Israel . Toward this end, the Syrian government engaged in an active process of recruiting former Nazis , including several former members of
36267-607: The leading government figures are Alawites , affiliated with Shia Islam. As a result, the opposition is winning support from the Sunni Muslim states, whereas the government is publicly supported by the Shia dominated Iran and the Lebanese Hezbollah . According to various sources, including the United Nations , up to 13,470–19,220 people have been killed, of which about half were civilians, but also including 6,035–6,570 armed combatants from both sides and up to 1,400 opposition protesters. Many more have been injured, and tens of thousands of protesters have been imprisoned. According to
36498-648: The levels of salinity in different seas, the relative composition of the dissolved salts is stable throughout the world's oceans. Seawater is too saline for humans to drink safely, as the kidneys cannot excrete urine as salty as seawater. Although the amount of salt in the ocean remains relatively constant within the scale of millions of years, various factors affect the salinity of a body of water. Evaporation and by-product of ice formation (known as "brine rejection") increase salinity, whereas precipitation , sea ice melt, and runoff from land reduce it. The Baltic Sea , for example, has many rivers flowing into it, and thus
36729-508: The mantle tend to drive the two plates apart. Parallel to these ridges and nearer the coasts, one oceanic plate may slide beneath another oceanic plate in a process known as subduction . Deep trenches are formed here and the process is accompanied by friction as the plates grind together. The movement proceeds in jerks which cause earthquakes, heat is produced and magma is forced up creating underwater mountains, some of which may form chains of volcanic islands near to deep trenches. Near some of
36960-401: The midst of World War I , two Allied diplomats (Frenchman François Georges-Picot and Briton Mark Sykes ) secretly agreed on the post-war division of the Ottoman Empire into respective zones of influence in the Sykes-Picot Agreement of 1916. Initially, the two territories were separated by a border that ran in an almost straight line from Jordan to Iran . However, the discovery of oil in
37191-416: The minimum "low tide" level. As the water recedes, it uncovers more and more of the foreshore , also known as the intertidal zone. The difference in height between the high tide and low tide is known as the tidal range or tidal amplitude. Most places experience two high tides each day, occurring at intervals of about 12 hours and 25 minutes. This is half the 24 hours and 50 minute period that it takes for
37422-532: The northeastern city of al-Qamishli . Signs of rioting were seen in the cities of Qamishli and Hasakeh . In 2005, Syria ended its military presence in Lebanon. Assassination of Rafic Hariri in 2005 led to international condemnation and triggered a popular Intifada in Lebanon , known as "the Cedar Revolution" which forced the Assad regime to end its 29-year old of military occupation in Lebanon . On 6 September 2007, foreign jet fighters, suspected as Israeli, reportedly carried out Operation Orchard against
37653-484: The northern Red Sea can reach 41‰. In contrast, some landlocked hypersaline lakes have a much higher salinity, for example, the Dead Sea has 300 grams (11 oz) dissolved solids per litre (300 ‰). While the constituents of table salt ( sodium and chloride ) make up about 85 percent of the solids in solution, there are also other metal ions such as magnesium and calcium , and negative ions including sulphate , carbonate , and bromide . Despite variations in
37884-486: The northern east parts of Syria while the rest of the region was dominated by the Amorites . Syria was called the Land of the Amurru (Amorites) by their Assyro-Babylonian neighbors. The Northwest Semitic language of the Amorites is the earliest attested of the Canaanite languages . Mari reemerged during this period, and saw renewed prosperity until conquered by Hammurabi of Babylon. Ugarit also arose during this time, circa 1800 BC, close to modern Latakia . Ugaritic
38115-430: The novel means of travelling westwards. He made landfall instead on an island in the Caribbean Sea and a few years later, the Venetian navigator John Cabot reached Newfoundland . The Italian Amerigo Vespucci , after whom America was named, explored the South American coastline in voyages made between 1497 and 1502, discovering the mouth of the Amazon River . In 1519 the Portuguese navigator Ferdinand Magellan led
38346-484: The ocean depths caused by the movement of deep water masses. A main deep ocean current flows through all the world's oceans and is known as the thermohaline circulation or global conveyor belt. This movement is slow and is driven by differences in density of the water caused by variations in salinity and temperature. At high latitudes the water is chilled by the low atmospheric temperature and becomes saltier as sea ice crystallizes out. Both these factors make it denser, and
38577-440: The ocean on a seasonal basis or vertical migrations daily, often ascending to feed at night and descending to safety by day. Ships can introduce or spread invasive species through the discharge of ballast water or the transport of organisms that have accumulated as part of the fouling community on the hulls of vessels. The demersal zone supports many animals that feed on benthic organisms or seek protection from predators and
38808-408: The ocean, travels through the atmosphere as vapour, condenses , falls as rain or snow , thereby sustaining life on land, and largely returns to the sea. Even in the Atacama Desert , where little rain ever falls, dense clouds of fog known as the camanchaca blow in from the sea and support plant life. In central Asia and other large land masses, there are endorheic basins which have no outlet to
39039-423: The open pelagic zone. The organisms living in the sea range from whales 30 metres (98 feet) long to microscopic phytoplankton and zooplankton , fungi, and bacteria. Marine life plays an important part in the carbon cycle as photosynthetic organisms convert dissolved carbon dioxide into organic carbon and it is economically important to humans for providing fish for use as food. Life may have originated in
39270-449: The original pan-Arab Ba'ath Party : one Iraqi-led ba'ath movement (ruled Iraq from 1968 to 2003) and one Syrian-led ba'ath movement was established. In the first half of 1967, a low-key state of war existed between Syria and Israel . Conflict over Israeli cultivation of land in the Demilitarized Zone led to 7 April pre-war aerial clashes between Israel and Syria. When the Six-Day War broke out between Egypt and Israel, Syria joined
39501-595: The overthrow of his government, and an end to nearly five decades of Ba’ath Party rule . Since spring 2011, the Syrian government deployed the Syrian Army to quell the uprising, and several cities were besieged, though the unrest continued. According to some witnesses, soldiers, who refused to open fire on civilians, were summarily executed by the Syrian Army. The Syrian government denied reports of defections, and blamed armed gangs for causing trouble. Since early autumn 2011, civilians and army defectors began forming fighting units, which began an insurgency campaign against
39732-529: The population living in poverty and 80% facing food insecurity . The Arab League , the United States , the European Union states , the Gulf Cooperation Council states , and other countries have condemned the use of violence against the protesters. China and Russia have avoided condemning the government or applying sanctions, saying that such methods could escalate into foreign intervention. However, military intervention has been ruled out by most countries. The Arab League suspended Syria's membership over
39963-430: The process of freezing, salt water and air are trapped between the ice crystals. Nilas may have a salinity of 12–15 ‰, but by the time the sea ice is one year old, this falls to 4–6 ‰. Seawater is slightly alkaline and had an average pH of about 8.2 over the past 300 million years. More recently, climate change has resulted in an increase of the carbon dioxide content of the atmosphere; about 30–40% of
40194-418: The quality of the inflowing water. Oceans contain the greatest quantity of actively cycled carbon in the world and are second only to the lithosphere in the amount of carbon they store. The oceans' surface layer holds large amounts of dissolved organic carbon that is exchanged rapidly with the atmosphere. The deep layer's concentration of dissolved inorganic carbon is about 15 percent higher than that of
40425-463: The region of Mosul just before the end of the war led to yet another negotiation with France in 1918 to cede this region to the British zone of influence, which was to become Iraq. The fate of the intermediate province of Zor was left unclear; its occupation by Arab nationalists resulted in its attachment to Syria . This border was recognized internationally when Syria became a League of Nations mandate in 1920 and has not changed to date. In 1920,
40656-403: The region which had lasted two decades. Syria prospered under Roman rule, being strategically located on the silk road, which gave it massive wealth and importance, making it the battleground for the rivaling Romans and Persians. Palmyra , a rich and sometimes powerful native Aramaic -speaking kingdom arose in northern Syria in the 2nd century; the Palmyrene established a trade network that made
40887-417: The rocks. This tends to undercut the cliff, and normal weathering processes such as the action of frost follows, causing further destruction. Gradually, a wave-cut platform develops at the foot of the cliff and this has a protective effect, reducing further wave-erosion. Material worn from the margins of the land eventually ends up in the sea. Here it is subject to attrition as currents flowing parallel to
41118-409: The same way as a wind-generated wave in shallow water but on a vastly greater scale. Either the trough or the crest of a tsunami can arrive at the coast first. In the former case, the sea draws back and leaves subtidal areas close to the shore exposed which provides a useful warning for people on land. When the crest arrives, it does not usually break but rushes inland, flooding all in its path. Much of
41349-420: The same year. Shishakli eventually abolished multipartyism altogether, but was himself overthrown in a 1954 coup and the parliamentary system was restored. However, by this time, power was increasingly concentrated in the military and security establishment. The weakness of Parliamentary institutions and the mismanagement of the economy led to unrest and the influence of Nasserism and other ideologies. There
41580-420: The sea and all the major groups of animals are represented there. Scientists differ as to precisely where in the sea life arose: the Miller-Urey experiments suggested a dilute chemical "soup" in open water, but more recent suggestions include volcanic hot springs, fine-grained clay sediments, or deep-sea " black smoker " vents, all of which would have provided protection from damaging ultraviolet radiation which
41811-436: The sea could be considered as brackish . Meanwhile, the Red Sea is very salty due to its high evaporation rate. Sea temperature depends on the amount of solar radiation falling on its surface. In the tropics, with the sun nearly overhead, the temperature of the surface layers can rise to over 30 °C (86 °F) while near the poles the temperature in equilibrium with the sea ice is about −2 °C (28 °F). There
42042-468: The sea for centuries and is the only state to have ever controlled all of its coast. The countries surrounding the Mediterranean and its marginal seas in clockwise order are Spain , France , Monaco , Italy , Slovenia , Croatia , Bosnia and Herzegovina , Montenegro , Albania , Greece , Turkey , Syria , Lebanon , Israel , Palestine ( Gaza Strip ), Egypt , Libya , Tunisia , Algeria , and Morocco ; Cyprus and Malta are island countries in
42273-537: The sea level has been higher than it is today. The main factor affecting sea level over time is the result of changes in the oceanic crust, with a downward trend expected to continue in the very long term. At the last glacial maximum , some 20,000 years ago, the sea level was about 125 metres (410 ft) lower than in present times (2012). For at least the last 100 years, sea level has been rising at an average rate of about 1.8 millimetres (0.071 in) per year. Most of this rise can be attributed to an increase in
42504-399: The sea under the influence of gravity. A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater
42735-553: The sea, separated from the ocean by mountains or other natural geologic features that prevent the water draining away. The Caspian Sea is the largest one of these. Its main inflow is from the River Volga , there is no outflow and the evaporation of water makes it saline as dissolved minerals accumulate. The Aral Sea in Kazakhstan and Uzbekistan, and Pyramid Lake in the western United States are further examples of large, inland saline water-bodies without drainage. Some endorheic lakes are less salty, but all are sensitive to variations in
42966-457: The sea. In addition, Northern Cyprus ( de facto state ) and two overseas territories of the United Kingdom ( Akrotiri and Dhekelia , and Gibraltar ) also have coastlines along the Mediterranean Sea. The drainage basin encompasses a large number of other countries, the Nile being the longest river ending in the Mediterranean Sea. The Ancient Egyptians called the Mediterranean Wadj-wr/Wadj-Wer/Wadj-Ur. This term (literally "great green")
43197-657: The seabed provides a range of habitats on or under the surface of the substrate which are used by creatures adapted to these conditions. The tidal zone with its periodic exposure to the dehydrating air is home to barnacles , molluscs and crustaceans . The neritic zone has many organisms that need light to flourish. Here, among algal-encrusted rocks live sponges , echinoderms , polychaete worms, sea anemones and other invertebrates. Corals often contain photosynthetic symbionts and live in shallow waters where light penetrates. The extensive calcareous skeletons they extrude build up into coral reefs which are an important feature of
43428-427: The seabed. These provide a biodiverse habitat for reef-dwelling organisms. There is less sea life on the floor of deeper seas but marine life also flourishes around seamounts that rise from the depths, where fish and other animals congregate to spawn and feed. Close to the seabed live demersal fish that feed largely on pelagic organisms or benthic invertebrates. Exploration of the deep sea by submersibles revealed
43659-481: The seas, which offers a wide range of marine habitats and ecosystems , ranging vertically from the sunlit surface and shoreline to the great depths and pressures of the cold, dark abyssal zone , and in latitude from the cold waters under polar ice caps to the warm waters of coral reefs in tropical regions . Many of the major groups of organisms evolved in the sea and life may have started there. The ocean moderates Earth's climate and has important roles in
43890-399: The seizure of power by Hafiz al-Assad . He effectively established an Alawi minority rule to consolidate power within his family. After Assad's death , his son Bashar al-Assad inherited the presidency in 2000. Since the Arab Spring in 2011, Syria has been embroiled in a multi-sided civil war , with involvement of different countries . The Islamic State (ISIS) captured many cities in
44121-423: The shortest shipping route between the multinational Gulf of Trieste and the Libyan coastline of the Gulf of Sidra is about 1,900 kilometres (1,200 mi). The water temperatures are mild in winter and warm in summer and give name to the Mediterranean climate type due to the majority of precipitation falling in the cooler months. Its southern and eastern coastlines are lined with hot deserts not far inland, but
44352-420: The sites of several ancient kingdoms and empires, including the Eblan civilization of the 3rd millennium BC . Damascus and Aleppo are cities of great cultural significance. During the Islamic rule, Damascus was the seat of the Umayyad Caliphate and a provincial capital for the Mamluk Sultanate in Egypt . The modern Syrian state was established in the mid-20th century after centuries of Ottoman rule , as
44583-418: The slope under the effect of gravity. The larger the breaking waves, the longer the beach and the more oblique the wave approach, the stronger is the longshore current. These currents can shift great volumes of sand or pebbles, create spits and make beaches disappear and water channels silt up. A rip current can occur when water piles up near the shore from advancing waves and is funnelled out to sea through
44814-470: The south side of the Taurus Mountains . In Europe, the largest basins are those of the Rhône , Ebro , Po , and Maritsa . The basin of the Rhône is the largest and extends up as far north as the Jura Mountains , encompassing areas even on the north side of the Alps . The basins of the Ebro, Po, and Maritsa, are respectively south of the Pyrenees , Alps, and Balkan Mountains , which are the major ranges bordering Southern Europe. Total annual precipitation
45045-432: The southwest . It is a republic comprising 14 governorates . Damascus is Syria's capital and largest city. With a population of 25.0 million across an area of 185,180 square kilometres (71,500 sq mi), it is the 57th most populous and 87th largest country. The name "Syria" historically referred to a wider region , broadly synonymous with the Levant, and known in Arabic as al-Sham . The modern state encompasses
45276-448: The strength of Syrian military technology, as it seemed feasible that Syria might attempt to retake İskenderun . Only heated debates in the United Nations lessened the threat of war. On 1 February 1958, Syrian President Shukri al-Quwatli and Egypt's Nasser announced the merging of Egypt and Syria, creating the United Arab Republic , and all Syrian political parties, as well as the communists therein, ceased overt activities. Meanwhile,
45507-429: The sun, the weather conditions and the turbidity of the water. Much light gets reflected at the surface, and red light gets absorbed in the top few metres. Yellow and green light reach greater depths, and blue and violet light may penetrate as deep as 1,000 metres (3,300 ft). There is insufficient light for photosynthesis and plant growth beyond a depth of about 200 metres (660 ft). Over most of geologic time,
45738-430: The surface and loops back on itself. It takes a thousand years for this circulation pattern to be completed. Besides gyres, there are temporary surface currents that occur under specific conditions. When waves meet a shore at an angle, a longshore current is created as water is pushed along parallel to the coastline. The water swirls up onto the beach at right angles to the approaching waves but drains away straight down
45969-495: The surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary little across the oceans. The most abundant solid dissolved in seawater is sodium chloride . The water also contains salts of magnesium , calcium , potassium , and mercury , amongst many other elements, some in minute concentrations. A wide variety of organisms , including bacteria , protists , algae , plants, fungi , and animals live in
46200-473: The surface layer and it remains there for much longer periods of time. Thermohaline circulation exchanges carbon between these two layers. Carbon enters the ocean as atmospheric carbon dioxide dissolves in the surface layers and is converted into carbonic acid , carbonate , and bicarbonate : It can also enter through rivers as dissolved organic carbon and is converted by photosynthetic organisms into organic carbon. This can either be exchanged throughout
46431-453: The temperature of the sea due to climate change , and the resulting slight thermal expansion of the upper 500 metres (1,600 ft) of water. Additional contributions, as much as one quarter of the total, come from water sources on land, such as melting snow and glaciers and extraction of groundwater for irrigation and other agricultural and human needs. Wind blowing over the surface of a body of water forms waves that are perpendicular to
46662-437: The term was later extended to the whole Mediterranean, it was also called Baḥr al-Maghrib ( بحر المغرب ) ("the Sea of the West"). A name that was used mainly for the western basin. In Turkish , it is the Akdeniz 'the White Sea'; in Ottoman, ﺁق دڭيز , which sometimes means only the Aegean Sea . The origin of the name is not clear, as it is not known in earlier Greek, Byzantine or Islamic sources. It may be to contrast with
46893-416: The time, while unofficial number stood at as many as 130,000. UNICEF reported that over 500 children have been killed in the 11 months until February 2012, Another 400 children have been reportedly arrested and tortured in Syrian prisons. Both claims have been contested by the Syrian government. Additionally, over 600 detainees and political prisoners have died under torture. Human Rights Watch accused
47124-507: The trade in western Europe and brought it to a halt. However, the Norsemen developed the trade from Norway to the White Sea , while also trading in luxury goods from Spain and the Mediterranean. The Byzantines in the mid-8th century retook control of the area around the north-eastern part of the Mediterranean. Venetian ships from the 9th century armed themselves to counter the harassment by Arabs while concentrating trade of Asian goods in Venice. The Fatimids maintained trade relations with
47355-487: The trade relations between Western and Eastern Europe while disrupting trade routes with Eastern Asian Empires. This, however, had the indirect effect of promoting trade across the Caspian Sea . The export of grains from Egypt was re-routed towards the Eastern world . Products from East Asian empires, like silk and spices, were carried from Egypt under the Arab rule to ports like Venice and Constantinople by sailors and Jewish merchants. The Viking raids further disrupted
47586-401: The transition from the Alborán Sea to the Strait of Gibraltar, the easternmost point is on the coast of the Gulf of Iskenderun in southeastern Turkey. The northernmost point of the Mediterranean is on the coast of the Gulf of Trieste near Monfalcone in northern Italy while the southernmost point is on the coast of the Gulf of Sidra near the Libyan town of El Agheila . Large islands in
47817-432: The two can produce broken, irregular seas. Constructive interference can cause individual (unexpected) rogue waves much higher than normal. Most waves are less than 3 m (10 ft) high and it is not unusual for strong storms to double or triple that height; offshore construction such as wind farms and oil platforms use metocean statistics from measurements in computing the wave forces (due to for instance
48048-431: The upper layers, the major part of the ocean exists in permanent darkness. As the different depth and temperature zones each provide habitat for a unique set of species, the marine environment as a whole encompasses an immense diversity of life. Marine habitats range from surface water to the deepest oceanic trenches , including coral reefs, kelp forests , seagrass meadows , tidepools , muddy, sandy and rocky seabeds, and
48279-409: The war and attacked Israel as well. In the final days of the war, Israel turned its attention to Syria, capturing two-thirds of the Golan Heights in under 48 hours. The defeat caused a split between Jadid and Assad over what steps to take next. Disagreement developed between Jadid, who controlled the party apparatus, and Assad, who controlled the military. The 1970 retreat of Syrian forces sent to aid
48510-403: The water sinks. From the deep sea near Greenland, such water flows southwards between the continental landmasses on either side of the Atlantic. When it reaches the Antarctic, it is joined by further masses of cold, sinking water and flows eastwards. It then splits into two streams that move northwards into the Indian and Pacific Oceans. Here it is gradually warmed, becomes less dense, rises towards
48741-426: The wave reaches a point where its deepest oscillations of the water contact the seabed , they begin to slow down. This pulls the crests closer together and increases the waves' height , which is called wave shoaling . When the ratio of the wave's height to the water depth increases above a certain limit, it " breaks ", toppling over in a mass of foaming water. This rushes in a sheet up the beach before retreating into
48972-551: The west almost by the Morocco–Spain border . The Mediterranean has played a central role in the history of Western civilization . Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about 2,500,000 km (970,000 sq mi), representing 0.7% of
49203-534: The west to the entrances to the Dardanelles and the Suez Canal in the east, the Mediterranean Sea is bounded by the coasts of Europe, Africa, and Asia and is divided into two deep basins: The drainage basin of the Mediterranean Sea is particularly heterogeneous and extends much further than the Mediterranean region. Its size has been estimated between 4,000,000 and 5,500,000 km (1,500,000 and 2,100,000 sq mi), depending on whether non-active parts (deserts) are included or not. The longest river ending in
49434-489: The world . Yamhad (modern Aleppo ) dominated northern Syria for two centuries, although Eastern Syria was occupied in the 19th and 18th centuries BC by the Old Assyrian Empire ruled by the Amorite Dynasty of Shamshi-Adad I , and by the Babylonian Empire which was founded by Amorites. Yamhad was described in the tablets of Mari as the mightiest state in the near east and as having more vassals than Hammurabi of Babylon. Yamhad imposed its authority over Alalakh , Qatna ,
49665-445: The world ocean, so global climate modelling makes use of ocean circulation models as well as models of other major components such as the atmosphere , land surfaces, aerosols and sea ice. Ocean models make use of a branch of physics, geophysical fluid dynamics , that describes the large-scale flow of fluids such as seawater. Surface currents only affect the top few hundred metres of the sea, but there are also large-scale flows in
49896-442: Was a Semitic language loosely related to the Canaanite languages, and developed the Ugaritic alphabet , considered to be the world's earliest known alphabet. The Ugaritic kingdom survived until its destruction at the hands of the marauding Indo-European Sea Peoples in the 12th century BC in what was known as the Late Bronze Age Collapse . Aleppo and the capital city Damascus are among the oldest continuously inhabited cities in
50127-420: Was already envisaging something of the expansion which took place after his death", and that the rapid march of his troops must have "impressed all those who heard of it". William Muir also believes that the expedition was important as Muhammad followed by 1000 men reached the confines of Syria, where distant tribes had now learnt his name, while the political horizon of Muhammad was extended. By AD 640, Syria
50358-424: Was also a synthesis between the Semitic Arameans and the remnants of the Indo-European Hittites , with the founding of a number of Syro-Hittite states centered in north central Aram (Syria) and south central Asia Minor (modern Turkey), including Palistin , Carchemish and Sam'al . A Canaanite group known as the Phoenicians came to dominate the coasts of Syria, (and also Lebanon and northern Palestine ) from
50589-417: Was conquered by the Arab Rashidun army led by Khalid ibn al-Walid . In the mid-7th century, the Umayyad dynasty , then rulers of the empire, placed the capital of the empire in Damascus. The country's power declined during later Umayyad rule; this was mainly due to totalitarianism, corruption and the resulting revolutions. The Umayyad dynasty was then overthrown in 750 by the Abbasid dynasty , which moved
50820-399: Was conquered by Rome. The Aramaic language has been found as far afield as Hadrian's Wall in Ancient Britain, with an inscription written by a Palmyrene emigrant at the site of Fort Arbeia . Control of Syria eventually passed from the Romans to the Byzantines , with the split in the Roman Empire. The largely Aramaic -speaking population of Syria during the heyday of the Byzantine Empire
51051-433: Was discovered at the field of Jbessa in 1940. Syria contains four terrestrial ecoregions: Syrian xeric grasslands and shrublands , Eastern Mediterranean conifer-sclerophyllous-broadleaf forests , Southern Anatolian montane conifer and deciduous forests , and Mesopotamian shrub desert . The country had a 2019 Forest Landscape Integrity Index mean score of 3.64/10, ranking it 144th globally out of 172 countries. Syria
51282-503: Was elected president in an election in which he ran unopposed. His election saw the birth of the Damascus Spring and hopes of reform, but by autumn 2001, the authorities had suppressed the movement, imprisoning some of its leading intellectuals. Instead, reforms have been limited to some market reforms. On 5 October 2003, Israel bombed a site near Damascus , claiming it was a terrorist training facility for members of Islamic Jihad . In March 2004, Syrian Kurds and Arabs clashed in
51513-465: Was eventually pardoned. He returned to Syria in 1937 after the signing of the Syrian-French Treaty. Syria and France negotiated a treaty of independence in September 1936, and Hashim al-Atassi was the first president to be elected under the first incarnation of the modern republic of Syria.

Coastal habitats extend from the shoreline to the edge of the continental shelf . Most marine life is found in coastal habitats, even though the shelf area occupies only 7 percent of the total ocean area. Open ocean habitats are found in the deep ocean beyond the edge of
52206-402: Was not burdensome to Syrians because the Turks respected Arabic as the language of the Quran , and accepted the mantle of defenders of the faith. Damascus was made the major entrepot for Mecca , and as such it acquired a holy character to Muslims, because of the beneficial results of the countless pilgrims who passed through on the hajj, the pilgrimage to Mecca. Ottoman administration followed
52437-400: Was one of the most ancient on earth, perhaps preceded by only that of Mesopotamia . The earliest recorded indigenous civilization in the region was the Kingdom of Ebla near present-day Idlib , northern Syria.

Dumat Al-Jandal was 800 kilometres (500 mi) from Medina, and Watt says that there was no immediate threat to Muhammad, other than the possibility that his communications to Syria and supplies to Medina would be interrupted. Watt says "It is tempting to suppose that Muhammad
53130-608: Was the name given by the Ancient Egyptians to the semi-solid, semi-aquatic region characterized by papyrus forests to the north of the cultivated Nile delta, and, by extension, the sea beyond.

The Romans called it Mare Magnum ("Great Sea") or Mare Internum ("Internal Sea") and, starting with
53361-634: Was tumultuous, with multiple military coup attempts shaking the country between 1949 and 1971. In 1958, Syria entered a brief union with Egypt , which was terminated in the 1961 coup d'état and was renamed as the Arab Republic of Syria in constitutional referendum . The 1963 coup d'état carried out by the military committee of the Ba'ath Party established a one-party state and ran Syria under emergency law from 1963 to 2011, effectively suspending constitutional protections for citizens. Internal power-struggles within Ba'athist factions caused further coups in 1966 and 1970 , which eventually resulted in
