Abstract: The advective regime connecting the northern Gulf of Alaska with Prince William Sound may affect recruitment and nutritional processes in Pacific herring. The Sound Ecosystem Assessment (SEA, Project \320) has shown that herring have significant dependence on Gulf of Alaska carbon. Herring are subject to changes in carbon flow occurring between the Gulf of Alaska and Prince William Sound. The first step in understanding how this fundamental environmental process affects herring recruitment is to isotopically analyze a time series of herring for which energetic data have been collected. This will expand upon the data series available from SEA, providing a total four-year time period.
