Abstract

Total (unfiltered) silver concentrations in higher latitudes of the North Atlantic (52-68 degrees N) are reported for the second Intergovernmental Oceanographic Commission (IOC) Global Investigation of Pollutants in the Marine Environment (GIPME) baseline survey of 1993. These silver concentrations(0.69-7.2 pM) are oceanographically consistent with those (0.24-9.6 pM) previously reported for lower latitudes in the eastern North and South Atlantic (Flegal et al,, 1995). However, surface ( less than or equal to 200 m) water concentrations of silver (0.69-4.6 pM) in the northern North Atlantic waters are, on average, ten-fold larger than those (0.25 pM) considered natural background concentrations in surface waters of the central Atlantic. In contrast, variations in deep far North Atlantic silver concentrations areassociated with discrete water masses. Consequently, the cycling of silverin the far North Atlantic appears to be predominantly controlled by external inputs and the advection of distinct water masses, in contrast to the nutrient-like biogeochemical cycling of silver observed in the central Atlantic and Pacific oceans.
