Ocean chemistry and deep-sea sediments

Global fluxes in the ocean constitute dissolved and particulate matter.We start with particulate matters. There are mainly two types ofsediment, biogenic and terrigenous (incl. volcanic) sediments. There is aminor amount of extraterrestrial sediments.• Biogenic sediment production of planktonic marine organism dependsupon both nutrients and sunlight and can be devided up in siliceousand calcareous oozes, made up by zooplankton and phytoplankton.Remember ocean circulation causes upwelling where highbiogenic sedimentation rates occur.
