The potential impact of elevated dissolved organic carbon (DOC) and nitrogen (DON) concentrations on the biogeochemical cycling of organic matter in the oceans is profound. Yet we are at an impasse in obtaining accurate measurements of DOC and DON. A Workshop in Seattle (15–19 July 1991) was conceived to bring order to the present uncertainties in these measurements and to make explicit recommendations for future analytical protocols and experimentation.
