Notes on the JGOFS North Atlantic Bloom Experiment—dissolved organic carbon intercomparison

Abstract

Using high temperature catalytic oxidation (HTCO), personnel from four laboratories analyzed water samples collected during the JGOFS North Atlantic Bloom study for their dissolved organic carbon (DOC) content. In general, good agreement was obtained. Values obtained on samples filtered and frozen compared well with those analyzed immediately after collection. DON analyses of the same frozen samples did not co-vary with DOC; thus far, DON results have only been reported by Moss Landing Marine Laboratories.
