Organic carbon fluxes

Fig. 10-15 Organic carbon fluxes with depth in the water column normalized to mean annual primary production rates at the sites of sediment trap deployment. The undulating line indicates the base of the euphotic zone the horizontal error bars reflect variations in mean annual productivity as well as replicate flux measurements during the same season or over several seasons vertical error bars are depth ranges of several sediment trap deployments and uncertainities in the exact depth location.

Where D is in cm yr and Depth in m. Although these two relationships explain some of the variability in D, it is clear that other environmental factors are also important, including sediment grain-size (Wheatcroft 1992) and the organic carbon flux (Trauth et al. 1997).

Roughly 90% of the organic matter that exits the euphotic zone of the ocean is degraded in the water column. Of the 10% of the organic carbon flux that reaches the seafloor, only about one-tenth escapes oxidation and is buried. Degradation of the organic matter that reaches the ocean sediments drives the reactions that control sediment diagenesis and benthic flux.
