All sciences are needed to understand the oceans. As an example, many
oceanographers had noticed that there were no calcium carbonate
deposits in certain deep portions of the oceans. They knew that there
were organisms that lived on the surface under this water, but for some
reason it did not reflect this in the bottom waters. After testing of
the water vertically, chemists noticed that cold water holds more CO2
which results in more carbonic acid with dissolve CaCO3
faster. This leads to the Carbonate Compensation Depth or CCD.
Chemical oceanographers also work with water masses to determine
their unique chemical composition. This is then used by physical
oceanographers to chart their movements.
