TEOS-10-DepthCalc
|
Seawater depth is a function of sea pressure and seawater density. The units of measurement are meters. Depth = sea pressure/(density*g) where seawater density is in g/cm3 and sea pressure is in dbar, and g is the acceleration of gravity and equals 9.8 m/s2. Calculated using TEOS-10 standard.
