Measurement UNESCO83-DensityCalc Seawater density calculated from conductivity, temperature and pressure sensor measurements. For sigma-t, density is reported as a function of temperature and salinity at pressure = 0, minus 1000. Fofonoff, N.P. and R.C. Millard Jr.,, 1983.

Measurement UNESCO83-DepthCalc Seawater depth calculated from pressure sensor measurements using UNESCO Technical Papers in Marine Science No. 44 formula. This empirical formula takes compressibility (density) into account. An ocean water column at 0 °C (t = 0) and 35 PSU (s = 35) is assumed. The gravity variation with latitude and pressure is computed. Then, depth is calculated from pressure. Fofonoff, N.P. and R.C. Millard Jr.,, 1983.
