Jean-François de Galaup, comte de Lapérouse
Jean-François de Galaup, comte de La Pérouse (1741–1788) was a French naval officer who led a round-the-world voyage of discovery and vanished with both ships in the South Pacific in 1788.
Jean-Michel Cousteau
Jean-Michel Cousteau, born in 1938 in Toulon, France, is a French ocean explorer and environmentalist, eldest son of Jacques-Yves Cousteau and founder of the Ocean Futures Society.
Jeffrey W. Book
Jeffrey W. Book is an American physical oceanographer at the Naval Research Laboratory in Mississippi, known for shallow-sea and strait circulation research and a 2011 Presidential Early Career Award.
Jeremy Wade
Jeremy Wade, full name Jeremy John Wade, is a British biologist, angler, and television presenter who hosted Animal Planet's River Monsters for nine seasons, investigating large freshwater fish worldwide.
JOIDES Resolution
The JOIDES Resolution was a riserless scientific drillship that drilled the ocean floor for core samples, serving international ocean drilling programs from 1985 until its retirement in September 2024.
Joint Global Ocean Flux Study
The Joint Global Ocean Flux Study (JGOFS) was an international marine research program launched in 1987 under SCOR to quantify carbon fluxes in the ocean and atmosphere.
Joint Typhoon Warning Center
The Joint Typhoon Warning Center (JTWC) is a joint U.S. Navy and Air Force command issuing tropical cyclone forecasts and warnings for the Pacific and Indian Oceans.
Jökulhlaup
Jökulhlaup, an Icelandic word now used internationally, is a glacial outburst flood caused by failure of an ice or sediment dam or by volcanic melting.
Juan de Fuca
Juan de Fuca, usually identified as the Greek mariner Apóstolos Valerianos, claimed in 1592 to have discovered the strait between Vancouver Island and Washington State that bears his name.
Kaidu River
The Kaidu River (开都河) is a 530 km inland river in Xinjiang, northwest China, rising in the Tianshan and supplying about 95 percent of Bosten Lake's water.
Karst hydrology
Karst hydrology is the study of water movement through karst, landscapes formed in soluble limestone and dolomite, which supply drinking water to a quarter of the world.
Kelvin wave
A Kelvin wave is a rotating-fluid wave trapped by the Coriolis effect against a coast or the equator, carrying warm water eastward across the Pacific during El Niño.
Kinematic wave theory
Kinematic wave theory is a simplified description of unsteady shallow water flow in which friction balances the water's weight component, so flow-dependent celerity can steepen waves into shocks.
Kuroshio Current (黒潮)
The Kuroshio, also known as the Japan current, is a warm ocean current flowing northeastward past Taiwan and Japan, the Pacific counterpart of the Gulf Stream.
Labrador Sea Water
Labrador Sea Water is a cold, fresh intermediate-depth water mass of the North Atlantic, formed by winter deep convection in the central Labrador Sea and spread across the Atlantic.
Lake acidification
Lake acidification is the process by which a lake's water becomes more acidic, caused mainly by acid rain and acid mine drainage. It killed fish in Scandinavian and North American lakes in the 1970s and 1980s.
Lake sediment coring
Lake sediment coring is the extraction of cylindrical sediment columns from lake beds, using gravity, piston, vibracorer, and drilling systems to recover layered records of past environments for paleolimnology, paleoclimatology, and contamination studies.
Lake stratification
Lake stratification, or thermal stratification, is the layering of a lake's water by density, typically into a warm epilimnion, a cold hypolimnion, and a thermocline between.
Lamont-Doherty Earth Observatory
Lamont-Doherty Earth Observatory, founded in 1949 on a Hudson River estate in Palisades, New York, is Columbia University's Earth science research center, known for seafloor mapping that laid the groundwork for plate tectonics.
Langmuir circulation
Langmuir circulation is a wind-driven pattern of counter-rotating vortices in lakes and the ocean, visible at the surface as parallel streaks of foam called windrows.
Large woody debris
Large woody debris (LWD), now often called large wood, is logs, root wads, and branches in stream channels large enough to resist immediate transport by the flow.
Lateral connectivity
Lateral connectivity is the water-mediated exchange of water, energy, materials, and organisms between a river channel and its floodplain, one of three dimensions of river connectivity.
Lead line (nautical)
A lead line, also called a sounding line, is a marked rope with a lead weight used for centuries to measure water depth and sample the seabed.
Leaf litter breakdown
Leaf litter breakdown is the decomposition of dead leaves in streams and rivers through leaching, microbial conditioning, and fragmentation, a key energy source for aquatic food webs.
Lee-Lueng Fu
Lee-Lueng Fu is a Taiwanese-American physical oceanographer at NASA's Jet Propulsion Laboratory who led satellite altimetry missions measuring sea level, including TOPEX/Poseidon and SWOT, and was elected to the National Academy of Engineering in 2008.
Lidar bathymetry
Lidar bathymetry is a remote sensing method that maps shallow seafloor depth by firing green laser pulses from aircraft, reaching roughly 50 m in clear coastal water.
Limnologica
Limnologica is a peer-reviewed scientific journal covering the ecology and management of inland waters, published by Elsevier and closely associated with the German Society for Limnology.
Limnological journals
Limnological journals are scholarly periodicals that publish research on inland waters such as lakes, rivers, and wetlands, with Limnology and Oceanography the flagship since 1956.
Limnology
Limnology, also called freshwater science, is the study of inland waters, including lakes, rivers, wetlands, and groundwater, as ecological systems linked to their drainage basins.
Limnology and Oceanography
Limnology and Oceanography is a peer-reviewed scientific journal published by the Association for the Sciences of Limnology and Oceanography, covering the study of inland waters and the sea.
