Gotthilf Hempel (born March 8, 1929) is a German marine biologist and oceanographer.
Hempel studied biology and geology at the universities of Mainz and Heidelberg. In 1952 he gained his Ph.D. with a study on the energetics of grasshopper jumps from Heidelberg University. He then went on to work as a scientific assistant at various research institutes in Wilhelmshaven, Heligoland, and Hamburg, where he habilitated with a thesis on the ecology of fry in 1963.
In 1967 he became a professor at the University of Kiel at the Institute of Marine Sciences (Institut für Meereskunde Kiel), where he remained director of the Department of Fisheries Biology for the next 14 years and served as Acting Director of the institute from 1972 to 1976.
In 1981, he helped found the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven whereupon he became the institution's first director. In the same year, he also became director of the Institute for Polar Ecology at the University of Kiel. In Bremerhaven, he initiated the construction of the polar research vessel PFS Polarstern. In 1992, he became the first director of the then newly founded Center for Marine Tropical Ecology at this time part of University of Bremen. Hempel retired in 1994.
He has been interested and active in research politics throughout his career. From 1963 to 1967 he worked for UNESCO and the FAO and from 1990 to 1996 he was a member of the Wissenschaftsrat , the scientific advisory committee of Germany. He has been and is an active proponent of scientific collaboration and education initiatives in underdeveloped countries, and has advocated a more sustainable exploitation of natural resources. Hempel is the editor of the journal Polar Biology , and he has also published several books. He has had more than 70 doctoral candidates, notably Daniel Pauly. From his time spent researching oceanological topics he has managed to spend over 1000 days aboard research vessels.
He became a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1989. [1] He was awarded the German Order of Merit (Grosses Verdienstkreuz) in 1993.
Antarctic krill is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms, sometimes reaching densities of 10,000–30,000 individual animals per cubic metre. It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their pelagic life cycle. It grows to a length of 6 centimetres (2.4 in), weighs up to 2 grams (0.071 oz), and can live for up to six years. It is a key species in the Antarctic ecosystem and in terms of biomass, is one of the most abundant animal species on the planet – approximately 500 million metric tons.
RV Polarstern is a German research icebreaker of the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven, Germany. Polarstern was built by Howaldtswerke-Deutsche Werft in Kiel and Nobiskrug in Rendsburg, was commissioned in 1982, and is mainly used for research in the Arctic and Antarctica. The ship has a length of 118 metres and is a double-hulled icebreaker. She is operational at temperatures as low as −50 °C (−58 °F). Polarstern can break through ice 1.5 m thick at a speed of 5 knots. Thicker ice of up to 3 m (9.8 ft) can be broken by ramming.
Daniel Pauly is a French-born marine biologist, well known for his work in studying human impacts on global fisheries and in 2020 was the most cited fisheries scientist in the world. He is a professor and the project leader of the Sea Around Us initiative at the Institute for the Oceans and Fisheries at the University of British Columbia. He also served as Director of the UBC Fisheries Centre from November 2003 to October 2008.
The Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research is located in Bremerhaven, Germany, and a member of the Helmholtz Association of German Research Centres. It conducts research in the Arctic, the Antarctic, and the high and mid latitude oceans. Additional research topics are: North Sea research, marine biological monitoring, and technical marine developments. The institute was founded in 1980 and is named after meteorologist, climatologist, and geologist Alfred Wegener.
The University of Bremen is a public university in Bremen, Germany, with approximately 23,500 people from 115 countries. It is one of 11 institutions which were successful in the category "Institutional Strategies" of the Excellence Initiative launched by the Federal Government and the Federal States in 2012. The university was also successful in the categories "Graduate Schools" and "Clusters of Excellence" of the initiative.
The Gottfried Wilhelm Leibniz Prize, or Leibniz Prize, is awarded by the German Research Foundation to "exceptional scientists and academics for their outstanding achievements in the field of research". Since 1986, up to ten prizes have been awarded annually to individuals or research groups working at a research institution in Germany or at a German research institution abroad. It is considered the most important research award in Germany.
The German Maritime Museum is a museum in Bremerhaven, Germany. It is part of the Gottfried Wilhelm Leibniz Scientific Community. The main museum building was opened on 5 September 1975 by then-president of Germany Walter Scheel, though scientific work already had started in 1971. In 2000, celebrating the 25th anniversary of the museum, the Hansekogge, a ship constructed around 1380 that was found in the Weser river in 1962, was presented to the public after having undergone a lengthy process of conservation in a large preservative-filled basin.
The Atlantic Data Base for Exchange Processes at the Deep Sea Floor (ADEPD) was a marine research project funded by the EU from 1998 to 2000 as part of MAST III. The project was coordinated by Prof. Dr. Karin Lochte at the Leibniz Institute for Baltic Sea Research, Warnemünde with contributions of ten European partners and one institute from the US.
Georg Adolf Otto Wüst was a German oceanographer. His pioneering work on the Atlantic Ocean provided a new view of the motions of water masses between the northern and southern hemispheres and the first evidence of the concentration of water mass spreading in western boundary currents.
Bremerhaven is a city on the east bank of the Weser estuary in northern Germany. It forms an exclave of the city-state of Bremen. The River Geeste flows through the city before emptying into the Weser.
