Abstract: This project is a component of the integrated Long-term Monitoring of Marine Conditions and Injured Resources and Services submitted by McCammon et al. This project fills three needs: understanding exposure levels (past and present) for species such as mussels, intertidal invertebrates, sea otters, and harlequin ducks, (2) understanding the natural degradation of quantity and composition of PAH over a long time course, and 3) definitive long-term source identification by measurement of geochemical biomarkers (triterpanes, hopanes, and steranes). The objectives are 1) to determine oil quantity and weathering in 12 PWS beaches 25 years post spill (with repeats every 5 years thereafter), 2) provide supplementary support analyses for other long-term monitoring collaborators, 3) maintain and expand the hydrocarbon database, and 4) produce annual, final, and published reports. The subset of PWS beaches to be monitored are those where sequestered oil is expected to linger for decades. At least three predictive data sets will be considered in determining which beaches are monitored: (1) mussel bed time series started in the early 1990s, (2) beach surveys that were continued up to 2004, and spatial modeling analysis that was initiated in 2008.
