Earth science > Physical oceanography 
radiolarian ooze
Earth science; Physical oceanography
A deep-sea sediment composed of at least 30% of the remains of siliceous radiolarians. These sediments occur in the equatorial Pacific and Indian ocean regions where the depth ...
Towed Ocean Bottom Instrument (TOBI)
Earth science; Physical oceanography
A deep–towed multi–sensor sonar sytem that comprises a two–sided 30 kHz sidescan sonar, a 7.5 kHz sub–bottom profiler sonar, a magnetometer, a temperature probe, a ...
reference level
Earth science; Physical oceanography
A depth, pressure or density level at which the horizontal current field is either known from direct measurements or indirectly estimated. This may be zero velocity surface or one ...
intensive parameter
Earth science; Physical oceanography
A determining parameter of a system that does not depend on the size and mass of the system, e.g. temperature, pressure, and concentration, as opposed to an extensive parameter.
extensive parameter
Earth science; Physical oceanography
A determining parameter of a system that is proportional to the size and mass of the system, e.g. volume, internal energy, enthalpy and entropy, as opposed to an intensive ...
Circulation Obviation Retrofit Kit (CORK)
Earth science; Physical oceanography
A device that allows boreholes to be isolated from the ocean water above the seabed and conditions in the hole to be monitored for long periods of time. CORK’s purpose is to ...
cyclosonde
Earth science; Physical oceanography
A device that allows the profiling of the water column by alternately rising to the surface and sinking to a predetermined depth. It does so by adjusting its buoyancy. This device ...
