carbon-carbon link
1.The main carbon modes of occurrence in the nepheloid layer are particulate organic carbon(POC),dissolved organic carbon(DOC), colloidal organic carbon(COC) and inorganic carbon, and the material exchange and transport of different carbon modes between nepheloid layer ambient seawater and sea bottom sediment take place under the actions of the bio-chemico-physico dynamic system, so the nepheloid layers play an important role in ocean carbon cycle and are a nonnegligible link in the entire ocean carbon cycle.
