Particulate inorganic carbon

Particulate inorganic carbon can be contrasted with dissolved inorganic carbon, the other form of inorganic carbon found in the ocean. These distinctions are important in chemical oceanography. Partic

Particulate organic matter

Particulate organic matter is a fraction of total organic matter operationally defined as that which does not pass through a filter pore size that typically ranges in size from 0.053 millimeters to 2
Marine particulate organic carbon (POC) POC includes components of living cells as well as dead material (detritus), and originates from both allochthonous and autochthonous sources. The POC pool can also exchange material with the dissolved OC (DOC) pool through aggregation and disaggregation of particles. This process and others may be involved in the formation of the molecularly uncharacterized component (MUC), which may incorporate both autochthonous and allochthonous OC.
