Global Distribution of Dissolved Organic Carbon in the Ocean
Topic outline

-
Now that organic carbon in seawater can be accurately measured, we finally have a complete picture of its global distribution. DOC concentrations in surface water vary widely from 60 - 80 μmol L-1 and decrease with depth. What do the changes in DOC concentrations in deep water mean?

Details of the oceanic DOC distribution were reported by Dennis A. Hansell & Craig A. Carlson, Nature, (1998) and Hansell et al. Their color contour map is shown below.
