Abstract: Prince William Sound is the wintering area for over 125,000 sea ducks, primarily Barrow's goldeneyes, three species of scoters, harlequins, and oldsquaws. More than 160,000 sea ducks, consisting mainly of these same species, winter in the nearshore waters of Kodiak and neighboring islands. In the spring, the Sound is a major migration area for sea ducks. In the summer in both areas, the numbers of some species are low, while remaining high to moderate for others. Sea ducks are heavily dependent on intertidal and subtidal marine invertebrates. Oldsquaws take a wide variety of foods and use invertebrates in the water column as well as bottom-dwelling animals. Scoters and goldeneyes utilize blue mussels and, like harlequins, consume a wide variety of clams, snails, and limpets. Bivalves, particularly blue mussels, are well-known for their ability to concentrate pollutants at high levels. The crude oil spilled from the Exxon Valdez may cause severe damage to marine invertebrates that support sea ducks year round, and bioaccumulation of pollutants in this food chain may result in uptake of hydrocarbons by sea ducks over a long period of time. Through integration with other studies, this study will determine the levels of hydrocarbons taken in by sea ducks, and will predict resultant physiological and life-history effects.
