WebMar 2, 2001 · Note that density (and sigma-t) varies with temperature and salinity but the typical values we find on the shelf range between 23.0 and 28.0. Note that the units on sigma-t are now "kg/m 3-1000". There is another density measure sometimes denoted "sigma_0" (where the last digit, a zero, is used to represent the greek letter theta). WebTwo physical processes contribute to this discrepancy between skin and bulk SSTs. 1. The skin effect, which arises as a result of conductive heat loss from the ocean, generally results in a skin temperature up to 0.4°C cooler than the bulk temperature, depending on the net heat flux and wind speed. 2.
