gradient current

Earth science; Oceanography

In oceanography, a current associated with horizontal pressure gradients in the ocean and determined by the condition that the pressure force due to the distribution of mass ...

undercurrent

Earth science; Oceanography

In oceanography, a water current flowing beneath a surface current at a different speed or in a different direction.

dynamic-height anomaly

Earth science; Oceanography

In oceanography, the excess of the actual geopotential difference, between two given isobaric surfaces , over the geopotential difference in a homogeneous water column of salinity ...

specific-volume anomaly

Earth science; Oceanography

In oceanography, the excess of the actual specific volume of the sea water at any point in the ocean over the specific volume of sea water of salinity 35 per mile ((s)) and ...

mixed layer

Earth science; Oceanography

In oceanography, the surface layer of virtually isothermal water, which frequently exists above the thermocline .

surface temperature (SEA)

Earth science; Oceanography

In oceanography, the temperature of the layer of sea water nearest the atmosphere. It is generally determined either as bucket temperature or injection temperature .

potential temperature

Earth science; Oceanography

In oceanography, the temperature that a water sample would attain if raised adiabatically to the sea surface. For the deepest points of the ocean, which are just over 10,000 ...
