Neutron activation analysis techniques were used to determine the total concentration of copper, manganese and zinc in 84 samples obtained from 28 stations in the Gulf of Mexico. All samples were oxidized with peroxydisulfuric acid and extracted with diethyldithiocarbamate before activation to remove most of the interferences from the major elements. Wide ranges in concentration were found for all three elements both vertically and horizontally. Coastal values for manganese (0.18-19.0 g/l.) were found to be about a magnitude higher than those in the open sea (0.05-0.88 g/l.). Copper and zinc were found often to have higher concentrations in the open sea than in coastal regions. Highest values in the open Gulf were usually found at the surface and at intermediate depths. The higher metal concentrations in the intermediate water appear to have their origin outside the Gulf of Mexico and it is suggested that this enrichment results from release of trace metals by decomposing organisms. Deeper waters were found to be uniformly low in all three elements.
