Shallow Subtidal Survey of the Washington Outer Coast and Olympic National Park to Determine the Distribution, Fate, and Effects of Spilled Bunker C Fuel Oil

摘要

The report provides an evaluation of the impacts of the bunker C fuel oil spill on the shallow subtidal benthic communities of the Washington coast. The study is designed to provide a subtidal extension of the intertidal investigation performed by Battelle Laboratories. As such, the study sites and many of the methodologies are the same. There are four objectives of the study. They are: (1) to identify and define from existing data, the probable distribution of subtidal deposits along the Washington coast, (2) to document petroleum hydrocarbon contamination in shallow subtidal sediments in the Olympic National Park and along the Washington outer coast, (3) to characterize petroleum hydrocarbon contamination in molluscan and other species' tissues of opportunity in subtidal habitats along the Washington outer coast, and (4) to collect the initial faunal and sediment samples required for possible future analyses should oil-spill related hydrocarbons be detected from initial sediment and tissue analyses.
