Damage Assessment Closeout-Injury Assessment of Hydrocarbon Uptake by Sea Ducks

The goal of this project was to determine whether the Exxon Valdez oil spill had measurable sublethal effects on six species of migratory and resident seaducks in Prince William Sound and the Kodiak Archipelago. The six seaduck species were harlequin ducks, Barrow's and common goldeneyes, and surf, black, and white-winged scoters. The harlequin ducks are both resident in and winter migrants to the oil spill area. The other species do not breed in the oil spill area but are winter migrants.

Recovery Status of Barrow's Goldeneyes

Data available at the onset of this project (population trends and indices of contaminant exposure) raised concern that Barrow's goldeneye populations may have been injured by the oil spill, may not be fully recovered, and may continue to suffer deleterious effects of the spill. This project is designed to critically assess the recovery status of Barrow's goldeneye populations through assemblage and analysis of all existent, relevant data.

Effects of temperature and mussel size on intertidal mussel bed infaunal communities: implications for climate change and biodiversity.

While mussel beds can withstand the changing tides, global climate change may cause damage to these diverse ecosystems. As the amount of carbon dioxide in the air increases, so does the amount of carbon dioxide dissolved in seawater. The resulting acidification changes the basic chemistry of the oceans and decreases the growth rate of organisms which rely on dissolved calcium carbonate to build their shells.

Sea Duck Joint Venture Strategic Plan 2008-2012

The fifteen species of sea ducks (Tribe Mergini) are the most poorly understood group of waterfowl in North America. The most basic biological information is unknown for some species. Few species have reliable population indices or estimates of annual productivity, and much of our knowledge is based on a very few, localized studies. Also, current survey design is unable to accurately estimate sea duck harvest.
