Copper in Sub-Arctic Waters of the Pacific Northwest

Abstract

Copper concentration data from the north-central continental shelf-slope of the Bering Sea and nearshore regions of the western Gulf of Alaska are summarized. Copper concentrations which increase toward the sediments were found in a frontally confined continental shelf water mass of the Bering Sea, and also in deep waters of restricted circulation of a fjord on the north-western Gulf of Alaska coastline. These data are indicative of a benthic flux of copper to overlying waters. Mass balance estimates suggest that the benthic remineralization and flux to the overlying waters in the shallow shelf of the Bering Sea contributes significantly to the copper input to the deep Bering basin. However, in the fjord basin of the Gulf of Alaska, remineralized copper from inshore surface sediments was estimated at less than 20% of copper added to surface waters. Also, most copper input could be accounted for trapped in accumulating fjord sediments.
