The compensation depth between photosynthesis and respiration of phytoplankton in the ocean must be dependent on some factors : the illumination at the surface, the transparency of the water, the biological character of the plankton present, and the temperature.

Calcium carbonate becomes more soluble at lower pH, so ocean acidification is likely to affect marine organisms with calcareous shells, such as oysters, clams, sea urchins and corals, and the carbonate compensation depth will rise closer to the sea surface.
13.
Since aragonite is more soluble than calcite and solubility increases with pressure, the depth at which the ocean is undersaturated with aragonite ( aragonite compensation depth ) is shallower than the depth at which it is undersaturated with calcite ( calcite compensation depth ).

A concern regarding the concept of compensation point is it assumes that phytoplankton remain at a fixed depth throughout a 24-hour period ( time frame in which compensation depth is measured ), but phytoplankton experience displacement due to isopycnals moving them tens of meters.
16.
Shallow marine waters are generally supersaturated in calcite, CaCO 3, so as marine organisms ( which often have shells made of calcite or its carbonate compensation depth " ( CCD ) below which the rate of supply of calcite equals the rate of dissolution, such that no calcite is deposited.
