The Woods Hole Oceanographic Institution is a private, nonprofit research and higher education facility dedicated to the study of marine science and engineering.
The mesopelagiczone, also known as the middle pelagic or twilight zone, is the part of the pelagic zone that lies between the photic epipelagic and the aphotic bathypelagic zones. It is defined by light, and begins at the depth where only 1% of incident light reaches and ends where there is no light; the depths of this zone are between approximately 200 to 1,000 meters below the ocean surface.
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.
Jason is a two-body remotely operated vehicle (ROV) designed, built, and operated by the National Deep Submergence Laboratory of the Woods Hole Oceanographic Institution (WHOI). Construction of Jason began in 1982 and was first launched in 1988, redesigned in 2002 as the second iteration of the ROV. The ROV allows scientists and explorers to have access to the seafloor without leaving the deck of a ship.
Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The word "diel" comes from Latin: diēs, lit. 'day', and means a 24-hour period. The migration occurs when organisms move up to the uppermost layer of the sea at night and return to the bottom of the daylight zone of the oceans or to the dense, bottom layer of lakes during the day. It is important to the functioning of deep-sea food webs and the biologically driven sequestration of carbon.
Susan Henrichs became provost of the University of Alaska Fairbanks (UAF) in July 2007, after serving as dean of the Graduate School and vice provost of UAF from 2003 to 2007.
Edward Brinton was a professor of oceanography and research biologist. His particular area of expertise was Euphausiids or krill, small shrimp-like creatures found in all the oceans of the world.
Mertensia ovum, also known as the Arctic comb jelly or sea nut, is a cydippid comb jelly or ctenophore first described as Beroe ovum by Johan Christian Fabricius in 1780. It is the only species in the genus Mertensia. Unusually among ctenophores, which normally prefer warmer waters, it is found in the Arctic and adjacent polar seas, mostly in surface waters down to 50 metres (160 ft).
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton. Planktivory can be an important mechanism of top-down control that contributes to trophic cascades in aquatic and marine systems. There is a tremendous diversity of feeding strategies and behaviors that planktivores utilize to capture prey. Some planktivores utilize tides and currents to migrate between estuaries and coastal waters; other aquatic planktivores reside in lakes or reservoirs where diverse assemblages of plankton are present, or migrate vertically in the water column searching for prey. Planktivore populations can impact the abundance and community composition of planktonic species through their predation pressure, and planktivore migrations facilitate nutrient transport between benthic and pelagic habitats.
Bettina Meyer is a German Antarctic researcher, best known for her work on the ecology and physiology of invertebrates in the pelagic zone. She is the head of the ecophysiology of pelagic key species working group at the Alfred Wegener Institute for Polar and Marine Research (AWI).
Karen Frances Wishner is an American oceanographer currently at University of Rhode Island and an elected fellow of the American Association for the Advancement of Science. Her interests include coastal shelf and zooplankton behavior and environment, and has published her findings.
Neocalanus cristatus is a species of copepod found primarily in the northern Pacific.
The Joint Global Ocean Flux Study (JGOFS) was an international research programme on the fluxes of carbon between the atmosphere and ocean, and within the ocean interior. Initiated by the Scientific Committee on Oceanic Research (SCOR), the programme ran from 1987 through to 2003, and became one of the early core projects of the International Geosphere-Biosphere Programme (IGBP).
The lipid pump sequesters carbon from the ocean's surface to deeper waters via lipids associated with overwintering vertically migratory zooplankton. Lipids are a class of hydrocarbon rich, nitrogen and phosphorus deficient compounds essential for cellular structures. This lipid carbon enters the deep ocean as carbon dioxide produced by respiration of lipid reserves and as organic matter from the mortality of zooplankton.
Cecilie Mauritzen is a Norwegian physical oceanographer who studies connections between ocean currents and climate change.
Sharon Louise Smith is an American marine ecologist known for her work on zooplankton and their ability to respond to climate change. Smith was Professor Emeritus at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami.
Mary-Louise Elizabeth Timmermans is a marine scientist known for her work on the Arctic Ocean. She is the Damon Wells Professor of Earth and Planetary Sciences at Yale University.
Kendra Lee Daly is an oceanographer known for her work on zooplankton, particularly in low oxygen regions of the ocean. She is a professor at the University of South Florida, and an elected fellow of the American Association for the Advancement of Science.
Stephanie Louise Pfirman is a professor at Arizona State University known for her work on sea ice, pollutants in sea ice, and how sea ice is changing over time. She is a fellow of the American Association for the Advancement of Science.
Callianira antarctica is a species of ctenophore that physically resembles Mertensia ovum, but lacks the oil sacs. Just like other ctenophores, over 95% of its body mass and composition is water.
