4332-529: The Roman Empire began to invade lands inhabited by the Germanic tribes, creating a short-lived Roman province of Germania between the Rhine and Elbe rivers. In 9 AD, three Roman legions were defeated by Arminius in the Battle of the Teutoburg Forest . The outcome of this battle dissuaded the Romans from their ambition of conquering Germania and is thus considered one of the most important events in European history . By 100 AD, when Tacitus wrote Germania , Germanic tribes had settled along

4446-430: The Saarland in 1935, remilitarised the Rhineland in 1936, annexed Austria in 1938, annexed the Sudetenland in 1938 with the Munich Agreement , and in violation of the agreement occupied Czechoslovakia in March 1939.

6270-476: The Glomar Challenger achieved the following accomplishments: The ship retrieved core samples in 9-meter-long (30 ft) cores with a diameter of 6.5 cm (2.5 inches). These cores are currently stored at three repositories in the US, Germany, and Japan. One half of each core is called the archive half and is preserved for future use. The working half of each core is used to provide samples for ongoing scientific research. The scientific results were published as

6384-428: The Holocaust , the German government persecuted minorities , including interning them in concentration and death camps across Europe. The regime systematically murdered 6 million Jews, at least 130,000 Romani , 275,000 disabled , thousands of Jehovah's Witnesses , thousands of homosexuals , and hundreds of thousands of political and religious opponents . Nazi policies in German-occupied countries resulted in

6498-452: The Oligocene. In addition, drilling onshore around the Ross Sea and on the Antarctic Peninsular also confirms that Antarctic ice sheet already existed at least since the Oligocene. The occurrence of ice-rafted debris in marine sediments is an indication of icebergs presence. Hence the earliest occurrence in the high latitudes could possibly reveal the inception of sea-level glaciations. It should be pointed out that there are factors influencing

6612-507: The Pacific and China. The colonial government in South West Africa (present-day Namibia ), from 1904 to 1907, carried out the annihilation of the local Herero and Namaqua peoples as punishment for an uprising; this was the 20th century's first genocide . The assassination of Austria's crown prince on 28 June 1914 provided the pretext for Austria-Hungary to attack Serbia and trigger World War I . After four years of warfare, in which approximately two million German soldiers were killed,

7068-407: The Ross shelf began to sink below sea-level about 25 Mya in the Oligocene. This suggests that Antarctic glaciers already advanced to the Ross Sea shelf. This age is consistent with the dating of the shallow unconformity seen on the seismic profiles. The unconformity was attributed to the glacier erosion when advancing to the coastal area. Development of the Circum Antarctic Current was also initiated in

7182-453: The Soviets pushed into Eastern Europe ; the Western allies landed in France and entered Germany despite a final German counteroffensive . Following Hitler's suicide during the Battle of Berlin , Germany signed the surrender document on 8 May 1945, ending World War II in Europe and Nazi Germany.

One major technological advance was the extended use of the holes after drilling. Geophysical and geochemical measurements were made during and after drilling, and occasionally long-term seismic monitoring devices were installed in

7524-429: The communist-controlled Socialist Unity Party of Germany , supported by the Stasi , an immense secret service. While East German propaganda was based on the benefits of the GDR's social programmes and the alleged threat of a West German invasion, many of its citizens looked to the West for freedom and prosperity. The Berlin Wall , built in 1961, prevented East German citizens from escaping to West Germany, becoming

Johannes Gutenberg introduced moveable-type printing to Europe, laying the basis for the democratization of knowledge . In 1517, Martin Luther incited the Protestant Reformation and his translation of the Bible began the standardization of the language; the 1555 Peace of Augsburg tolerated

7752-418: The continent This interpretation of Antarctic glaciation history based on marine sediments was subsequently supported by the onshore study of the Antarctic Peninsular and by the coring results around McMurdo Ice Shelf. Micropaleontologic data from deep sea sediments around the Antarctic continental margin indicate that since at least the late Oligocene-early Miocene, surface waters were relatively cool. With

7866-493: The continued cooling trend, the cold water mass gradually expanded northward until early Pliocene during which an intensified cooling episode resulted in a temperature minimum as evidenced by the northward shift of the silica/carbonate facies boundary. This deduction is similar to the conclusion based on ice-rated debris studies. Surface temperatures inferred from the oxygen and carbon isotope analyses of both benthonic and planktonic foraminifera in high-latitude marine sediments show

7980-405: The creation of a new currency in 1924 ushered in the Golden Twenties , an era of artistic innovation and liberal cultural life. The worldwide Great Depression hit Germany in 1929. Chancellor Heinrich Brüning 's government pursued a policy of fiscal austerity and deflation which caused unemployment of nearly 30% by 1932. The Nazi Party led by Adolf Hitler became the largest party in

After 1990, Germany and Russia worked together to establish a "strategic partnership" in which energy development became one of

8208-536: The criminal and the protection of the public. With the exceptions of petty crimes, tried by a single professional judge, and of serious political crimes, all charges are adjudicated by mixed tribunals where lay judges ( Schöffen ) and professional judges preside together. As of 2016, Germany's murder rate stood at a low of 1.18 murders per 100,000. In 2018, the overall crime rate fell to its lowest since 1992. Same-sex marriage has been legal in Germany since 2017, and LGBT rights are generally protected in

Hence the earliest occurrence should be considered as the minimum age of ice rafting at sample locations. Investigations of ice-rafted debris reasonably conclude that the Antarctic ice sheet was initiated at least 25 Mya and cumulated at about 4.5 Mya, as evidenced by ice-rafted debris reaching farthest away from

8550-521: The early 1930s, the Texas Company developed the first mobile steel barges for drilling in the brackish coastal areas of the Gulf of Mexico . In 1937, Pure Oil and its partner Superior Oil used a fixed platform to develop a field 1 mile (1.6 km) offshore of Calcasieu Parish, Louisiana in 14 feet (4.3 m) of water. In 1938, Humble Oil built a mile-long wooden trestle with railway tracks into

East Germany was an Eastern Bloc state under political and military control by the Soviet Union via occupation forces and the Warsaw Pact . Although East Germany claimed to be a democracy, political power was exercised solely by leading members ( Politbüro ) of

8778-681: The ecclesiastical territories were secularised and annexed. In 1806 the Imperium was dissolved; France, Russia, Prussia, and the Habsburgs (Austria) competed for hegemony in the German states during the Napoleonic Wars . Following the fall of Napoleon , the Congress of Vienna founded the German Confederation, a loose league of 39 sovereign states . The appointment of the emperor of Austria as

8892-467: The established term integrated operations . The increased use of subsea facilities helps achieve the objective of keeping more workers onshore. Subsea facilities are also easier to expand, with new separators or different modules for different oil types, and are not limited by the fixed floor space of an above-water installation. Offshore oil production involves environmental risks, most notably oil spills from oil tankers or pipelines transporting oil from

9006-635: The existence of salt domes . Oil companies received samples after an agreement to publish their analysis. The potential of oil beneath deep ocean salt domes remains an important avenue for commercial development today. As for the purpose of the scientific exploration, one of the most important discoveries was made when the crew drilled 17 holes at 10 different locations along an oceanic ridge between South America and Africa . The retrieved core samples provided strong proof for continental drift and seafloor renewal at rift zones . This confirmation of Alfred Wegener 's theory of continental drift strengthened

9120-415: The first jack-up rigs began appearing from specialized offshore drilling contractors. The first semi-submersible resulted from an unexpected observation in 1961. Blue Water Drilling Company owned and operated the four-column submersible Blue Water Rig No.1 in the Gulf of Mexico for Shell Oil Company . As the pontoons were not sufficiently buoyant to support the weight of the rig and its consumables, it

9234-722: The first submerged oil wells in salt water were drilled in the portion of the Summerland field extending under the Santa Barbara Channel in California . The wells were drilled from piers extending from land out into the channel. Other notable early submerged drilling activities occurred on the Canadian side of Lake Erie in the 1900s and Caddo Lake in Louisiana in the 1910s. Shortly thereafter wells were drilled in tidal zones along

9348-597: The government was completed in 1999, and modernisation of the East German economy was scheduled to last until 2019. Since reunification, Germany has taken a more active role in the European Union , signing the Maastricht Treaty in 1992 and the Lisbon Treaty in 2007, and co-founding the eurozone . Germany sent a peacekeeping force to secure stability in the Balkans and sent German troops to Afghanistan as part of

9462-401: The holes. This extended understanding of the dynamic processes involved in plate tectonics . Another technological advance involved the introduction of the hydraulic piston corer (HPC) in 1979, which permitted the recovery of virtually undisturbed cores of sediment. This greatly enhanced the ability of scientists to study ancient ocean environments. From August 11, 1968, to November 11, 1983,

9576-859: The last time with DSDP in November 1983. Parts of the ship, such as its dynamic positioning system, engine telegraph, and thruster console, are stored at the Smithsonian Institution in Washington, D.C. With the advent of larger and more advanced drilling ships, the JOIDES Resolution replaced the Glomar Challenger in January 1985. The new program, called the Ocean Drilling Program (ODP), continued exploration from 1985 to 2003, at which point it

9690-597: The mobile units are anchored to the seabed; however, in water deeper than 1,500 metres (4,900 ft), the semi-submersibles and drillships are maintained at the required drilling location using dynamic positioning . Around 1891, the first submerged oil wells were drilled from platforms built on piles in the fresh waters of the Grand Lake St. Marys in Ohio . The wells were developed by small local companies such as Bryson, Riley Oil, German-American and Banker's Oil. Around 1896,

9804-469: The most important factors. As a result of the cooperation, Germany imported most of its natural gas and crude oil from Russia. Germany's development policy functions as a distinct sector within its foreign policy framework. It is formulated by the Federal Ministry for Economic Cooperation and Development and carried out by the implementing organisations. The German government sees development policy as

9918-641: The nation. Germany has a network of 227 diplomatic missions abroad and maintains relations with more than 190 countries. Germany is a member of NATO , the OECD , the G7 , the G20 , the World Bank and the IMF . It has played an influential role in the European Union since its inception and has maintained a strong alliance with France and all neighbouring countries since 1990. Germany promotes

10032-460: The need to provide very large production facilities. Production and drilling facilities may be very large and a large investment, such as the Troll A platform standing on a depth of 300 meters (980 ft). Another type of offshore platform may float with a mooring system to maintain it on location. While a floating system may be lower cost in deeper waters than a fixed platform, the dynamic nature of

10146-639: The north, Poland and Czechia to the east, Austria and Switzerland to the south, and France , Luxembourg , Belgium , and the Netherlands to the west. Germany is also bordered by the North Sea and, at the north-northeast, by the Baltic Sea. German territory covers 357,596 km (138,069 sq mi). Elevation ranges from the mountains of the Alps (highest point: the Zugspitze at 2,963 metres or 9,721 feet) in

10260-458: The ocean bottom could have been as great as 1,299 m (4,262 feet). To replace the bit, the drill string must be raised, a new bit attached, and the string remade down to the bottom. However, the crew had to thread this string back into the same drill hole. The technique for this formidable task was accomplished on June 14, 1970, in the Atlantic Ocean in 3,000 m (10,000 feet) of water off

10374-489: The ocean floor is probably no older than 200 million years. This is in comparison with the 4.5 billion-year age of the Earth. The International Phase of Ocean Drilling (IPOD) began in 1975 with the Federal Republic of Germany , Japan , the United Kingdom , the Soviet Union , and France joining the United States in field work aboard the Glomar Challenger and in post-cruise scientific research. The Glomar Challenger docked for

10488-481: The oceanic basalt were estimated based on magnetic lineations generated at the spreading center as the sea floor pulled apart. Sediments immediately overlying the basalt should have ages similar to the age of magnetic stripes. This is confirmed by the micropaleontologic analyses of the basal sediments sampled above the penetrated basalts. These analyses furthermore substantiate that Australia was separated from Antarctic 85 Mya [million years ago] Based on paleo-soil study,

10602-587: The party system has been dominated by the Christian Democratic Union and the Social Democratic Party of Germany . So far every chancellor has been a member of one of these parties. However, the smaller liberal Free Democratic Party and the Alliance 90/The Greens have also been junior partners in coalition governments . Since 2007, the democratic socialist party The Left has been a staple in

10716-661: The people' (see also the Latinised form Theodiscus ), derived from * þeudō , descended from Proto-Indo-European * tewtéh₂- 'people', from which the word Teutons also originates. Pre-human ancestors, the Danuvius guggenmosi , who were present in Germany over 11 million years ago, are theorized to be among the earliest ones to walk on two legs. Ancient humans were present in Germany at least 600,000 years ago. The first non-modern human fossil (the Neanderthal )

10830-503: The peoples east of the Rhine . The German term Deutschland , originally diutisciu land ('the German lands'), is derived from deutsch ( cf. Dutch ), descended from Old High German diutisc 'of the people' (from diot or diota 'people'), originally used to distinguish the language of the common people from Latin and its Romance descendants . This in turn descends from Proto-Germanic * þiudiskaz 'of

10944-472: The permanent president reflected the Congress's rejection of Prussia 's rising influence. Disagreement within restoration politics partly led to the rise of liberal movements, followed by new measures of repression by Austrian statesman Klemens von Metternich . The Zollverein , a tariff union, furthered economic unity. In light of revolutionary movements in Europe , intellectuals and commoners started

11058-493: The platform to onshore facilities, and from leaks and accidents on the platform (e.g. Deepwater Horizon oil spill and Ixtoc I oil spill ). Produced water is also generated, which is water brought to the surface along with the oil and gas; it is usually highly saline and may include dissolved or unseparated hydrocarbons. Federal Republic of Germany – in Europe  (light green & dark grey) – in

11172-496: The platforms introduces many challenges for the drilling and production facilities. The ocean can add several thousand meters or more to the fluid column. The addition increases the equivalent circulating density and downhole pressures in drilling wells, as well as the energy needed to lift produced fluids for separation on the platform. The trend today is to conduct more of the production operations subsea , by separating water from oil and re-injecting it rather than pumping it up to

11286-482: The printed books were scanned and prepared for electronic presentation by the Texas A&;M University College of Geosciences. DSDP completed four drilling programs; Legs 28, 29, 35 and 36 around Antarctica during four Austral summers, 1972–73, 1973–74, 1974–75 and 1975–76. These programs were focused on two main objectives: Cenozoic global paleoclimatic changes and plate tectonic movements around Antarctica. There were

11400-618: The produced hydrocarbons and the materials used during the drilling operation. Controversies include the ongoing US offshore drilling debate . There are many different types of facilities from which offshore drilling operations take place. These include bottom founded drilling rigs ( jackup barges and swamp barges ), combined drilling and production facilities either bottom founded or floating platforms, and deepwater mobile offshore drilling units (MODU) including semi-submersibles or drillships . These are capable of operating in water depths up to 3,000 metres (9,800 ft). In shallower waters

11514-408: The proposal of a single, ancient land mass, which is called Pangaea . The samples gave further evidence to support the plate tectonics theory , which at the time attempted to explain the formation of mountain ranges, earthquakes, and oceanic trenches . Another discovery was how youthful the ocean floor is in comparison to Earth's geologic history. After analysis of samples, scientists concluded that

11628-642: The purpose of operating aircraft with an invention known as the 'seadrome'. The first purpose-built drilling semi-submersible Ocean Driller was launched in 1963 by ODECO .. Since then, many semi-submersibles have been purpose-designed for the drilling industry mobile offshore fleet. The first offshore drillship was the CUSS 1 developed for the Mohole project to drill into the Earth's crust. As of June 2010, there were over 620 mobile offshore drilling rigs (jackups, semisubs, drillships, barges, etc.) available for service in

11742-445: The sea at McFadden Beach on the Gulf of Mexico, placing a derrick at its end – this was later destroyed by a hurricane. In 1945, concern for American control of its offshore oil reserves caused President Harry Truman to issue an Executive Order unilaterally extending American territory to the edge of its continental shelf, an act that effectively ended the 3-mile limit " freedom of the seas " regime. In 1946, Magnolia drilled at

11856-419: The seabed). Offshore manned facilities also present logistics and human resources challenges. An offshore oil platform is a small community in itself with cafeteria, sleeping quarters, management and other support functions. In the North Sea, staff members are transported by helicopter for a two-week shift. They usually receive higher salary than onshore workers do. Supplies and waste are transported by ship, and

11970-649: The south to the shores of the North Sea ( Nordsee ) in the northwest and the Baltic Sea ( Ostsee ) in the northeast. The forested uplands of central Germany and the lowlands of northern Germany (lowest point: in the municipality Neuendorf-Sachsenbande , Wilstermarsch at 3.54 metres or 11.6 feet below sea level ) are traversed by such major rivers as the Rhine, Danube and Elbe. Significant natural resources include iron ore, coal, potash , timber, lignite , uranium , copper, natural gas, salt, and nickel. Most of Germany has

12084-854: The southeast regions have more extreme temperatures. From February 2019 – 2020, average monthly temperatures in Germany ranged from a low of 3.3 °C (37.9 °F) in January 2020 to a high of 19.8 °C (67.6 °F) in June 2019. Average monthly precipitation ranged from 30 litres per square metre in February and April 2019 to 125 litres per square metre in February 2020. Average monthly hours of sunshine ranged from 45 in November 2019 to 300 in June 2019. The territory of Germany can be divided into five terrestrial ecoregions : Atlantic mixed forests , Baltic mixed forests , Central European mixed forests , Western European broadleaf forests , and Alps conifer and mixed forests . As of 2016 , 51% of Germany's land area

12198-722: The subsequent decisive Prussian victory in the Austro-Prussian War of 1866 enabled him to create the North German Confederation which excluded Austria . After the defeat of France in the Franco-Prussian War , the German princes proclaimed the founding of the German Empire in 1871. Prussia was the dominant constituent state of the new empire; the King of Prussia ruled as its Kaiser, and Berlin became its capital. In

12312-446: The supply deliveries need to be carefully planned because storage space on the platform is limited. Today, much effort goes into relocating as many of the personnel as possible onshore, where management and technical experts are in touch with the platform by video conferencing. An onshore job is also more attractive for the aging workforce in the petroleum industry , at least in the western world. These efforts among others are contained in

12426-553: The world. Over the next 30 months, the second phase consisted of drilling and coring in the Atlantic , Pacific , and Indian Ocean as well as the Mediterranean and Red Sea . Technical and scientific reports followed during the period. The second phase of DSDP ended on August 11, 1972. The success of the Glomar Challenger was almost immediate. On one of the sites with a water depth of 1,067 m (3,501 feet), core samples revealed

12540-588: The worldwide offshore rig fleet. One of the world's deepest hubs is currently the Perdido in the Gulf of Mexico, floating in 2,438 meters (7,999 ft) of water. It is operated by Royal Dutch Shell and was built at a cost of $ 3 billion. The deepest operational platform is the Petrobras America Cascade FPSO in the Walker Ridge 249 field in 2,600 meters (8,500 ft) of water. Offshore drilling

12654-625: Was discovered in the Neander Valley . Similarly dated evidence of modern humans has been found in the Swabian Jura , including 42,000-year-old flutes which are the oldest musical instruments ever found, the 40,000-year-old Lion Man , and the 41,000-year-old Venus of Hohle Fels . The Nebra sky disk , created during the European Bronze Age , has been attributed to a German site. The Germanic peoples are thought to have emerged from

12768-550: Was replaced by the Integrated Ocean Drilling Program (IODP). Although itself a remarkable engineering accomplishment, the Glomar Challenger saw many advances in deep-ocean drilling. One problem solved involved the replacement of worn drill bits. A length of pipe suspended from the ship down to the bottom of the sea might have been as long as 6,243 m (20,483 feet). The maximum depth penetrated through

12882-491: Was the seventh-highest in the world . In response to the 2022 Russian invasion of Ukraine , Chancellor Olaf Scholz announced that German military expenditure would be increased past the NATO target of 2%, along with a one-time 2022 infusion of 100 billion euros, representing almost double the 53 billion euro military budget for 2021. In 2023, military spending according to NATO criteria amounted to $ 73.1 billion, or 1.64% of

12996-416: Was towed between locations at a draught midway between the top of the pontoons and the underside of the deck. It was noticed that the motions at this draught were very small, and Blue Water Drilling and Shell jointly decided to try operating the rig in the floating mode. The concept of an anchored, stable floating deep-sea platform had been designed and tested back in the 1920s by Edward Robert Armstrong for
