Abstract: The proposed study is to develop and implement a statistically rigorous field study and spatial modeling analysis to produce maps showing the probability of lingering oil in areas of Prince William Sound and the Gulf of Alaska that were affected by the Exxon Valdez oil spill. We will also estimate the area and volume of oiled sediments in these areas as of 2007. Sediment samples will be analyzed to fingerprint the source of the oil residues, characterize them as to the degree of weathering and risk to exposed biota, and determine treatability using bioremediation. The results will provide key data for use in developing more detailed remediation plans and priority areas for remediation. The probability maps will allow researchers to identify locations where oil persists with much greater precision, leading to more sensitive studies of the long-term effects of the lingering oil on biota in the spill-impact regions.
