Abstract

Dissolved organic carbon (DOC) is by far the largest of the organic carbon reservoirs in the oceans with a carbon load that for many years was accepted to be approximately zoo Gt C (Hedges 1987) It is made up of a very complex mixture of chemicals, which are generally known collectively as ‘dissolved organic matter’ or DOM,and which derive either directly from biological processes or from the enzymatic or bacterial degradation of defunct organisms. The heterogeneous nature of the composition of DOM is also reflected in its molecular size distribution which ranges from that of the simplest organic molecules up to complex macromolecules whose properties lie at an indistinct boundary between truly dissolved and colloidal or particulate matter (Gough and Mantoura 1991).
