Abstract: The results of previous EVOS-funded work on modeling of the lingering subsurface oil in PWS on adjacent shorelines were correlated with reduced probability of suitable habitat use by sea otters in 1998 and 2008. This work will repeat the spatial modeling of the distribution of sea otters in 2013 to determine if this effect persists through 2013, the most recent year for which population data for sea otters in PWS are available. In addition, a desk-top exercise will be conducted to determine likely treatment methods and estimated costs for restoration of sites selected based on existing site field data, statistical modeling studies, and the field bioremediation study of four beaches. Modeling results for the locations of lingering subsurface oil will be used to produce a database of sites contaminated with moderate oil residue (MOR) and heavy oil residue (HOR). Sites with the same level of contamination will be added to the database. For each site in the database, the Principal Investigators will evaluate approaches for accelerating the removal of the lingering oil. The evaluation will include assessment of the technical (engineering) feasibility and cost. The appropriate approaches will be ranked and presented.
