79-572: The Coastal Range consists of two parallel ranges, which run east and west along the coast of the Caribbean Sea . The Cojedes River separates the western end of the Coastal Range from the Cordillera de Mérida to the southeast. The range is divided into eastern and western sections by the wide bay between Cape Codera and Cumaná . In the eastern section of the range, the parallel ranges are known as

158-409: A defined barometric pressure . Generally, the pressure used to set the altimeter is the barometric pressure that would exist at MSL in the region being flown over. This pressure is referred to as either QNH or "altimeter" and is transmitted to the pilot by radio from air traffic control (ATC) or an automatic terminal information service (ATIS). Since the terrain elevation is also referenced to MSL,

237-432: A few metres, in timeframes ranging from minutes to months: Between 1901 and 2018, the average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities

316-438: A reference datum for mean sea level (MSL). It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (contrast with flight level ), and in the atmospheric sciences , and in land surveying . An alternative is to base height measurements on a reference ellipsoid approximating the entire Earth, which is what systems such as GPS do. In aviation, the reference ellipsoid known as WGS84

395-691: A relatively shallow sea compared to other bodies of water. The pressure of the South American Plate to the east of the Caribbean causes the region of the Lesser Antilles to have high volcanic activity. A very serious eruption of Mount Pelée in 1902 caused many casualties. The Caribbean sea floor is also home to two oceanic trenches : the Cayman Trench and the Puerto Rico Trench , which put

474-463: A sharp reduction in greenhouse gas emissions, this may increase to hundreds of millions in the latter decades of the century. Local factors like tidal range or land subsidence will greatly affect the severity of impacts. For instance, sea level rise in the United States is likely to be two to three times greater than the global average by the end of the century. Yet, of the 20 countries with

553-605: A year visit the area, including (in 1991–1992) about 8 million cruise ship tourists. Tourism based upon scuba diving and snorkeling on coral reefs of many Caribbean islands makes a major contribution to their economies. These three form the SSS islands that with the ABC islands comprise the Dutch Caribbean , of which the BES islands are not direct Kingdom constituents but subsumed with

632-405: Is a type of vertical datum  – a standardised geodetic datum  – that is used, for example, as a chart datum in cartography and marine navigation , or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels . A common and relatively straightforward mean sea-level standard

711-488: Is because the sea is in constant motion, affected by the tides, wind , atmospheric pressure, local gravitational differences, temperature, salinity , and so forth. The mean sea level at a particular location may be calculated over an extended time period and used as a datum . For example, hourly measurements may be averaged over a full Metonic 19-year lunar cycle to determine the mean sea level at an official tide gauge . Still-water level or still-water sea level (SWL)

790-478: Is called coral bleaching , and can lead to the devastation of large areas of reef. Over 42% of corals are completely bleached, and 95% are experiencing some type of whitening. Historically the Caribbean is thought to contain 14% of the world's coral reefs. The habitats supported by the reefs are critical to such tourist activities as fishing and diving , and provide an annual economic value to Caribbean nations of US$ 3.1–4.6 billion. Continued destruction of

869-707: Is concentrated around coral reefs where there is little variation in water temperature, purity and salinity. Leeward side of lagoons provide areas of growth for sea grasses . Turtle grass ( Thalassia testudinum ) is common in the Caribbean as is manatee grass ( Syringodium filiforme ) which can grow together as well as in fields of single species at depths up to 20 m (66 ft). Another type shoal grass ( Halodule wrightii ) grows on sand and mud surfaces at depths of up to 5 m (16 ft). In brackish water of harbours and estuaries at depths less than 2.5 m (8 ft 2 in) widgeongrass ( Ruppia maritima ) grows. Representatives of three species belonging to

948-427: Is due to change in either the volume of water in the world's oceans or the volume of the oceanic basins . Two major mechanisms are currently causing eustatic sea level rise. First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the oceans. Second, as ocean temperatures rise, the warmer water expands. Many factors can produce short-term changes in sea level, typically within

1027-411: Is endangered. The Antilles along with Central America lie in the flight path of migrating birds from North America so the size of populations is subject to seasonal fluctuations. Parrots and bananaquits are found in forests. Over the open sea can be seen frigatebirds and tropicbirds . The Caribbean region has seen a significant increase in human activity since the colonization period. The sea

1106-476: Is endangered. The rhinoceros iguana from the island of Hispaniola which is shared between Haiti and the Dominican Republic is also endangered. The region has several types of sea turtle ( loggerhead , green turtle , hawksbill , leatherback turtle , Atlantic ridley and olive ridley ). Some species are threatened with extinction. Their populations have been greatly reduced since the 17th century –

1185-483: Is increasingly used to define heights; however, differences up to 100 metres (328 feet) exist between this ellipsoid height and local mean sea level. Another alternative is to use a geoid -based vertical datum such as NAVD88 and the global EGM96 (part of WGS84). Details vary in different countries. When referring to geographic features such as mountains, on a topographic map variations in elevation are shown by contour lines . A mountain's highest point or summit

1264-408: Is instead a long-term average of tide gauge readings at a particular reference location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales . Current sea level rise is mainly caused by human-induced climate change . When temperatures rise, mountain glaciers and polar ice sheets melt, increasing the amount of water in the oceans, while

1343-445: Is one of the largest oil production areas in the world, producing approximately 170 million tons per year. The area also generates a large fishing industry for the surrounding countries, accounting for 500,000 tonnes (490,000 long tons; 550,000 short tons) of fish a year. Human activity in the area also accounts for a significant amount of pollution . The Pan American Health Organization estimated in 1993 that only about 10% of

1422-681: Is the Cayman Trough , between the Cayman Islands and Jamaica , at 7,686 m (25,217 ft) below sea level . The Caribbean coastline has many gulfs and bays : the Gulf of Gonâve , the Gulf of Venezuela , the Gulf of Darién , Golfo de los Mosquitos , the Gulf of Paria and the Gulf of Honduras . The Caribbean Sea has the world's second-largest barrier reef , the Mesoamerican Barrier Reef . It runs 1,000 km (620 mi) along

1501-447: Is the level of the sea with motions such as wind waves averaged out. Then MSL implies the SWL further averaged over a period of time such that changes due to, e.g., the tides , also have zero mean. Global MSL refers to a spatial average over the entire ocean area, typically using large sets of tide gauges and/or satellite measurements. One often measures the values of MSL with respect to

1580-723: Is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise , with another 42% resulting from thermal expansion of water . Sea level rise lags behind changes in the Earth 's temperature by many decades, and sea level rise will therefore continue to accelerate between now and 2050 in response to warming that has already happened. What happens after that depends on human greenhouse gas emissions . If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 slightly over 30 cm (1 ft) from now and approximately 60 cm (2 ft) from

1659-681: Is the national flower of Jamaica and the Bayahibe rose ( Pereskia quisqueyana ) which is the national flower of the Dominican Republic and the ceiba which is the national tree of both Puerto Rico and Guatemala . The mahogany is the national tree of the Dominican Republic and Belize . The caimito ( Chrysophyllum cainito ) grows throughout the Caribbean. In coastal zones there are coconut palms and in lagoons and estuaries are found thick areas of black mangrove and red mangrove ( Rhizophora mangle ). In shallow water flora and fauna

1738-456: Is the second most polluted sea. Pollution (in the form of up to 300,000 tonnes of solid garbage dumped into the Caribbean Sea each year) is progressively endangering marine ecosystems, wiping out species, and harming the livelihoods of the local people, which is primarily reliant on tourism and fishing. KfW took part in a €25.7 million funding agreement to eliminate marine trash and boost

1817-527: Is typically illustrated with the AMSL height in metres, feet or both. In unusual cases where a land location is below sea level, such as Death Valley, California , the elevation AMSL is negative. It is often necessary to compare the local height of the mean sea surface with a "level" reference surface, or geodetic datum, called the geoid . In the absence of external forces, the local mean sea level would coincide with this geoid surface, being an equipotential surface of

The lower elevations of the mountains are mostly covered by the La Costa xeric shrublands ecoregion of the deserts and xeric shrublands biome . The Araya and Paria xeric scrub occupies the arid zones of the Araya and Paria peninsulas, except the montane areas of the Paria Peninsula, which are included in the La Costa xeric shrublands ecoregion. The Araya and Paria xeric scrub also includes Isla Margarita and extends south onto

2291-569: The Sea of the Antilles became a common alternative name for the "Caribbean Sea" in various European languages. Spanish dominance in the region remained undisputed during the first century of European colonization. From the 16th century, Europeans visiting the Caribbean region distinguished the "South Sea" (the Pacific Ocean south of the isthmus of Panama) from the "North Sea" (the Caribbean Sea north of

The geoid includes a significant depression in the Indian Ocean , whose surface dips as much as 106 m (348 ft) below the global mean sea level (excluding minor effects such as tides and currents). Precise determination of a "mean sea level" is difficult because of the many factors that affect sea level. Instantaneous sea level varies substantially on several scales of time and space. This

2686-418: The height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,949.903 mi) at the poles and 6,371.001 km (3,958.756 mi) on average. This flattened spheroid , combined with local gravity anomalies , defines

A joint mission of NASA and CNES , TOPEX/Poseidon was followed by Jason-1 in 2001 and the Ocean Surface Topography Mission on the Jason-2 satellite in 2008. Height above mean sea level ( AMSL ) is the elevation (on the ground) or altitude (in the air) of an object, relative to

2844-973: The 19th century. With high emissions it would instead accelerate further, and could rise by 1.0 m ( 3 + 1 ⁄ 3  ft) or even 1.6 m ( 5 + 1 ⁄ 3  ft) by 2100. In the long run, sea level rise would amount to 2–3 m (7–10 ft) over the next 2000 years if warming stays to its current 1.5 °C (2.7 °F) over the pre-industrial past. It would be 19–22 metres (62–72 ft) if warming peaks at 5 °C (9.0 °F). Rising seas affect every coastal and island population on Earth. This can be through flooding, higher storm surges , king tides , and tsunamis . There are many knock-on effects. They lead to loss of coastal ecosystems like mangroves . Crop yields may reduce because of increasing salt levels in irrigation water. Damage to ports disrupts sea trade. The sea level rise projected by 2050 will expose places currently inhabited by tens of millions of people to annual flooding. Without

The global MSL

4266-415: The existing seawater also expands with heat. Because most of human settlement and infrastructure was built in response to a more-normalized sea level with limited expected change, populations affected by sea level rise will need to invest in climate adaptation to mitigate the worst effects or, when populations are at extreme risk, a process of managed retreat . The term above sea level generally refers to

Halophila baillonii has been found only in the Lesser Antilles . Marine biota in

4424-482: The geoid is referred to as (mean) ocean surface topography . It varies globally in a typical range of ±1 m (3 ft). Several terms are used to describe the changing relationships between sea level and dry land. The melting of glaciers at the end of ice ages results in isostatic post-glacial rebound , when land rises after the weight of ice is removed. Conversely, older volcanic islands experience relative sea level rise, due to isostatic subsidence from

4503-624: The greatest exposure to sea level rise, twelve are in Asia , including Indonesia , Bangladesh and the Philippines. The resilience and adaptive capacity of ecosystems and countries also varies, which will result in more or less pronounced impacts. The greatest impact on human populations in the near term will occur in the low-lying Caribbean and Pacific islands . Sea level rise will make many of them uninhabitable later this century. Pilots can estimate height above sea level with an altimeter set to

4582-504: The height of planetary features. Local mean sea level (LMSL) is defined as the height of the sea with respect to a land benchmark, averaged over a period of time long enough that fluctuations caused by waves and tides are smoothed out, typically a year or more. One must adjust perceived changes in LMSL to account for vertical movements of the land, which can occur at rates similar to sea level changes (millimetres per year). Some land movements occur because of isostatic adjustment to

4661-425: The land; hence a change in relative MSL or ( relative sea level ) can result from a real change in sea level, or from a change in the height of the land on which the tide gauge operates, or both. In the UK, the ordnance datum (the 0 metres height on UK maps) is the mean sea level measured at Newlyn in Cornwall between 1915 and 1921. Before 1921, the vertical datum was MSL at the Victoria Dock, Liverpool . Since

Changes in ground-based ice volume also affect local and regional sea levels by the readjustment of the geoid and true polar wander . Atmospheric pressure , ocean currents and local ocean temperature changes can affect LMSL as well. Eustatic sea level change (global as opposed to local change)

5056-403: The most diverse marine habitats in the world, but they are fragile ecosystems. When tropical waters become unusually warm for extended periods of time, microscopic plants called zooxanthellae , which are symbiotic partners living within the coral polyp tissues, die off. These plants provide food for the corals and give them their color. The result of the death and dispersal of these tiny plants

5135-410: The north and its convergence with the Euramerica basin decreased in size. The next stage of the Caribbean Sea's formation began in the Triassic . Powerful rifting led to the formation of narrow troughs, stretching from modern Newfoundland to the Gulf of Mexico's west coast, forming siliciclastic sedimentary rocks . In the early Jurassic due to powerful marine transgression , water broke into

5214-412: The northern Atlantic as the Guiana Current and part of the North Equatorial Current enter the sea on the east. On the western side of the sea, the trade winds influence a northerly current which causes an upwelling and a rich fishery near Yucatán .

The tropical rainforest climates include lowland areas near the Caribbean Sea from Costa Rica north to Belize , as well as the Dominican Republic and Puerto Rico , while the more seasonal dry tropical savanna climates are found in Cuba , northern Venezuela , and southern Yucatán, Mexico . Arid climates are found along the extreme northern coast of Venezuela out to the islands including Aruba and Curaçao , as well as

5846-528: The same isthmus). The Caribbean Sea had been unknown to the populations of Eurasia until after 1492 when Christopher Columbus sailed into Caribbean waters to find a sea route to Asia. At that time, the Americas were generally unknown to most Europeans, although they had been visited in the 10th century by the Vikings . Following Columbus's discovery of the islands, the area was quickly colonized by several Western cultures (initially Spain , then later England ,

5925-451: The seawater is about 3.6%, and its density is 1,023.5–1,024.0 kg/m (63.90–63.93 lb/cu ft). The surface water color is blue-green to green . The Caribbean's depth in its wider basins and deep-water temperatures are similar to those of the Atlantic. Atlantic deep water is thought to spill into the Caribbean and contribute to the general deep water of its sea. The surface water (30 m; 100 ft) acts as an extension of

6004-532: The sewage from the Central American and Caribbean Island countries is properly treated before being released into the sea. The region has been famous for its rum production - the drink is first mentioned in records from Barbados in around 1650, although it was likely to have been produced beforehand across the other islands. The Caribbean region supports a large tourism industry. The Caribbean Tourism Organization calculates that about 12 million people

6083-410: The surface do not exceed 3 °C (5.4 °F). Over the past 50 years, the Caribbean has gone through three stages: cooling until 1974, a cold phase with peaks during 1974–1976 and 1984–1986, and finally a warming phase with an increase in temperature of 0.6 °C (1.1 °F) per year. Virtually all temperature extremes were associated with the phenomena of El Niño and La Niña . The salinity of

6162-507: The times of the Russian Empire , in Russia and its other former parts, now independent states, the sea level is measured from the zero level of Kronstadt Sea-Gauge. In Hong Kong, "mPD" is a surveying term meaning "metres above Principal Datum" and refers to height of 0.146 m (5.7 in) above chart datum and 1.304 m (4 ft 3.3 in) below the average sea level. In France,

6241-411: The weight of cooling volcanos. The subsidence of land due to the withdrawal of groundwater is another isostatic cause of relative sea level rise. On planets that lack a liquid ocean, planetologists can calculate a "mean altitude" by averaging the heights of all points on the surface. This altitude, sometimes referred to as a "sea level" or zero-level elevation , serves equivalently as a reference for
