The diffuse field of marine analytical organic chemistry is systematically analyzed to select schemes for measuring the trace amounts of dissolved organic compounds which can be adopted as standard, rapid, routine tools to advance the oceanographic understanding of this important aspect of the ocean. The many methods considered for measuring dissolved organic compounds in seawater have been systematically reduced to three systems that are potentially routine and rapid for shipboard work. These include quantitative gas chromatographic analysis of all amino acids and qualitative results for histidine, cystine, tryptophan, and arginine; gas chromatographic analysis of lipids including light hydrocarbons, fatty acids, and sterols, and; autoanalysis with tetrazoleum blue after charcoal adsorption for soluble sugar compounds like glucose, sucrose, and fructose. Pumping systems or glass samplers on a chemically inert hydrographic wire followed by pre-centrifugation and inverse multiple filtration in combination with a selected analytical scheme will provide a system for routine analysis of seawater. Synoptic data of these compounds can be compared with total organic carbon which is currently the only routine analysis for organics in seawater.
