Organic carbon, or carbon contained in organisms, both past and present, is stored in a
variety forms in the ocean.
Form of Organic Matter
Relative Abundance (%) in the
Dissolved Organic Matter
Particulate Organic Matter
Amazing, only 1/10,000th of the organic carbon in the sea is
locked up in fish.
Most organic matter in the ocean is dead,
occurring in dissolved compounds or small particles floating in the water
(we will learn more about this in
expedition 16 where we join a dive in the Monterey submarine canyon)!
