Abstract: The goals of project Subtidal Study #8 are (1) to evaluate the internal consistency of sediment and mussel tissue hydrocarbon data, and (2) to objectively identify the presence of Exxon Valdez petroleum hydrocarbons in these samples. The first goal is necessary to minimize the effects of errors in sample collection, documentation and analysis that are inevitable with a large number of samples collected for several different projects, and that are chemically analyzed using a complex procedure. The more of these errors that can be objectively identified, the greater will be the power of subsequent statistical tests. The second goal is necessary to provide an objective evaluation of the persistence and geographic extent of petroleum hydrocarbon contamination of these samples. This evaluation will provide a common reference for the participating projects, will minimize duplication of expensive analytical effort, and will provide the most comprehensive view of contamination possible with these data.

Once Exxon Valdez petroleum hydrocarbons have been objectively and reliably identified in samples, the results can be mapped to yield a picture of the overall extent of contamination. By including results from all the projects that collected sediment or mussel tissue samples, the most complete and detailed maps of oil contamination will be prepared, providing a common reference for the participating projects. This, in turn, will provide scientific investigators and the general public with the most accurate indication of the persistence and geographic extent of oil contaminated sediments and mussels.
