sound fixing and ranging floats (SOFAR)
Earth science; Physical oceanography
Subsurface floats used since the mid 1970s that freely drift at prescribed pressures. These provide direct measurements of the ocean circulation by sending acoustic pulses, ...
eXpendable Conductivity (XCTD)
Earth science; Physical oceanography
Temperature and Depth instrument. The accuracy of XCTD probes is 0.02° C in temperature and 0.03 psu in salinity, and they are rated to about 1000 m depth. They typically cost 20 ...
falling tide
Earth science; Physical oceanography
That interval of the tidal cycle between a high water and the following low water. This is also known as ebb tide.
export flux
Earth science; Physical oceanography
That organic matter (particulate and dissolved) exported from the upper productive layer of the ocean into the deep sea to balance primary production over large time and space ...
viscous sublayer
Earth science; Physical oceanography
That part of a boundary layer where the viscous stress is much larger than the Reynolds stress.
cryosphere
Earth science; Physical oceanography
That part of the climate system consisting of the ice fields of Antarctica and Greenland, other continental snow and ice fields, sea ice and permafrost. At present the Antarctic ...
thermohaline circulation
Earth science; Physical oceanography
That part of the ocean circulation driven by temporal and spatial differences in both the salinity and temperature of the waters that comprise the world ocean. A simplified ...
