positive feedback
Earth science; Physical oceanography
A type of feedback in which a perturbation to a system causes an amplification of the process, and thus enhances itself. An example is the ice-albedo feedback mechanism.
Madeira Mode Water
Earth science; Physical oceanography
A type of Mode Water formed north of Madeira in the North Atlantic Ocean. It is characterized by a summer thermostad at 70-150 m depth and provides a major contribution to the ...
North Pacific Central Mode Water (NPCMW)
Earth science; Physical oceanography
A type of mode water found in the subtropical gyre in the North Pacific, and first discussed by Nakamura (1996) and Suga et al. (1997). NPCMW is distributed mainly between 30–40°N ...
North Pacific Subtropical Mode Water (NPSTMW)
Earth science; Physical oceanography
A type of mode water found in the subtropical gyre in the North Pacific. The NPSTMW thermostad has a core temperature range of 16°–19° C centered at 150°–160° E south of the ...
over–the–horizon radar (OTH)
Earth science; Physical oceanography
A type of radar originally developed to detect military targets far beyond the optical horizon. Radio waves in the 5 to 28 MHz range are reflected from the ionosphere and reach up ...
Prydz Bay Bottom Water (PBBW)
Earth science; Physical oceanography
A type of regionally modified Circumpolar Deep Water (CDW) which, along with several other types of regionally modified and previously defined types of CDW, is now usually defined ...
grease ice
Earth science; Physical oceanography
A type of sea ice defined by the WMO as: A later stage of freezing than frazil ice when the crystals have coagulated to form a soupy layer on the surface. Grease ice reflects ...
