velocimeter

8.46  velocimeter. Device used to measure the time traveled by short pulses between a projector and a receiver of known separation, and thus to calculate the local speed of...

bathythermograph

8.45  bathythermograph. Plot of water temperature in the ocean as a function of depth. Alternatively, a device used to measure water temperature in the ocean as a function of depth.

volume scattering coefficient

8.44  volume scattering coefficient. Quotient of the differential scattering cross section of the volume under consideration divided by that volume. Unit, inverse meter per steradian [1/(m...

volume scattering strength

8.43  volume scattering strength. Ten times the base 10 logarithm of the ratio of differential backscattering cross section per unit volume to the reciprocal of the reference distance. Unit, decibel (dB). Annotation...
