Temperature variations with latitude. Notice the decrease in salinity at the equator which is due to increased precipitation at the equator

Carbonate Compensation Depth The CCD is the depth at which calcareous skeletons of marine animals accumulate at the same rate at which they dissolve. Depending on the mineral structure of CaCO3, the CCD is called calcite compensation depth (trigonal structure) or aragonite compensation depth (rhombic structure), respectively.

Dissolved Salts and Substances Conservative constituents includes those that are not removed or added by living organisms (Duxbury) Non-conservation constituents include ions and molecules that can fluctuate through chemical and biological processes (i.e., nitrogen, phosphorus…) Redfield Ratio C:Si:N:P = 106:40:16:1
