Uwe Kils
Uwe Kils is a German marine biologist specializing in Antarctic biology. Career His work led to the development of instruments for ''in situ'' observation of underwater fauna, including the ecoSCOPE and the first software for full speed video processing. Later work at Kiel included the study of predator-prey interactions of juvenile herring and plankton, for which a floating laboratory was built called ATOLL.Kils, U.: ; U.S. GLOBEC NEWS Technology Forum Number 8: 6–9.

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and therm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EcoSCOPE
The ecoSCOPE is an optical sensor system, deployed from a small remotely operated vehicle ( ROV) or fibre optic cable, to investigate behavior and microdistribution of small organisms in the ocean. Deployment Although an ROV may be very small and quiet, it is impossible to approach feeding herring closer than 40 cm. The ecoSCOPE allows observation of feeding herring from a distance of only 4 cm. From 40 cm, the herrings' prey ( copepods) in front of the herring are invisible due to the deflection of light by phytoplankton and microparticles in highly productive waters where herring live. With the ecoSCOPE, the predators are illuminated by natural light, the prey by a light sheet, projected via a second endoscope from strobed LEDs (2 ms, 100% relative intensity at 700 nm, 53% at 690 nm, 22% at 680 nm, 4% at 660 nm, 0% at 642 nm). By imitating the long, thin snout of the garfish protruding into the security sphere of the alert herrings, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herring
Herring are forage fish, mostly belonging to the family of Clupeidae. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of ''Clupea'' (the type genus of the herring family Clupeidae) are recognised, and comprise about 90% of all herrings captured in fisheries. The most abundant of these species is the Atlantic herring, which comprises over half of all herring capture. Fish called herring are also found in the Arabian Sea, Indian Ocean, and Bay of Bengal. Herring played an important role in the history of marine fisheries in Europe, and early in the 20th century, their study was fundamental to the development of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled. Herring are also known as "sil ...

Plankton
Plankton are the diverse collection of organisms found in Hydrosphere, water (or atmosphere, air) that are unable to propel themselves against a Ocean current, current (or wind). The individual organisms constituting plankton are called plankters. In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales. Marine plankton include bacteria, archaea, algae, protozoa and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries. Freshwater plankton are similar to marine plankton, but are found in the freshwaters of lakes and rivers. Plankton are usually thought of as inhabiting water, but there are also airborne versions, the aeroplankton, that live part of their lives drifting in the atmosphere. These include plant spores, pollen and wind-scattered seeds, as well as microorganisms swept into the air from terrestrial dust storms and oceanic plankton swept into the air ...

ATOLL (oceanography)
The Antarctic Technology Offshore Lagoon Laboratory (ATOLL) was a floating oceanographic laboratory for ''in situ'' observation experiments. This facility also tested instruments and equipment for polar expeditions. The ATOLL hull was the largest fiberglass structure ever built at that time. It was in operation from 1982 to 1995. Structure and infrastructure The ATOLL was composed of three curved fiberglass elements, each long and having a draught of only . For towing, the elements could be assembled in a long S-shape; in operation, the elements would form a horseshoe shape surrounding water surface. The lab provided ample space for twelve researchers. The laboratory contained a lab, storage and supply facilities, a dormitory, computer room, and a fireplace. The laboratory was installed and operated in the Baltic Sea (and the Bay of Kiel in particular) at the initiative and under the direction of Uwe Kils, at the Institute of Oceanography (''Institut für Meereskunde'') of ...

Heinz Maier-Leibnitz-Preis
The Heinz Maier-Leibnitz-Preis (Heinz Maier-Leibnitz Prize), in honor and memory of the German physicist Heinz Maier-Leibnitz, is funded by the ''Bundesministerium für Bildung und Forschung'' (BMBF, German Ministry of Education and Research), and it is awarded by a selection committee appointed by the ''Deutsche Forschungsgemeinschaft'' (DFG, German Research Foundation) and the BMBF. Since 2013, there are ten recipients of the prize and each receives 20,000 Euros, which is an increase over the original 16,000 Euros that had been given to six recipients per year until 2012. Nominees for the award may be put forward by: *Members of the DFG Review Boards *Research universities of the Federal Republic of Germany *The ''Union der deutschen Akademien der Wissenschaften'' (Union of the German Academies of Sciences and Humanities)Union der deutschen Akademien der Wissenschaften' *The Max Planck Society *The Helmholtz Association of German Research Centres *The Fraunhofer Society *The G ...

Euphausia Superba
Antarctic krill (''Euphausia superba'') 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 (open ocean) life cycle. It grows to a length of , weighs up to , 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 tons, corresponding to 300 to 400 trillion individuals). Life cycle The main spawning season of Antarctic krill is from January to March, both above the continental shelf and also in the upper region of deep sea oceanic areas. In the typical way of all krill, the male attaches a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notothenioidei
Notothenioidei is one of 19 suborders of the order Perciformes. The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica. Evolution and geographic distribution The Southern Ocean has supported fish habitats for 400 million years; however, modern notothenioids likely appeared sometime after the Eocene epoch. This period marked the cooling of the Southern Ocean, resulting in the stable, ice-cold conditions that have persisted to the present day. Another key factor in the evolution of notothenioids is the preponderance of the Antarctic Circumpolar Current (ACC), a large, slow-moving current that extends to the seafloor and precludes most migration to and from the Antarctic region. These unique environmental conditions in concert with the key evolutionary innovation of Antif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
