This paper reports the results of a field study which took place around an exploratory well located in the Santa Barbara Channel. This study was designed to test for significant temporal and spatial differences in the concentrations of a number of drilling fluid-associated metals in both the sediments and biota. Temporal changes in the distribution of Ba, Cd, Cr, Cu, Hg, Ni, Pb, and Zn were examined in the sediments, and the bioaccumulation and subcellular distribution of these metals were examined in three benthic invertebrate species before and after drilling. Statistically significant increases in the accumulation of several of the metals were found in the surface sediments down current from the site after drilling with Ba showing the most pronounced increase. Statistically significant increases in the bioaccumulation of Ba were also observed in two of the three species examined, Cyclocardia ventricosa and Pactinaria californiensis. Within these organisms the majority of the Ba was localized in the granular pellets (>97%) and less than 0.1% accumulated in the cytosol. These data indicate that although bioaccumulation of Ba occurs in some species immediately down current from the well, most of it remains in an insoluble for, presumably as BaSO{sub 4}.
