Summary

Recent interest has increased related to developing alternative sources of renewable energy to reduce dependence on oil. Some of those sources will include power generation infrastructure and support activities located within continental shelf waters, and potentially within deeper waters off the U.S. Pacific coast and beyond state waters (i.e., outside three nautical miles). Currently, the Bureau of Ocean Energy Management (BOEM) is considering renewable energy proposals off the coast of Oregon. The 2011-2012 Pacific Continental Shelf Environmental Assessment (PaCSEA) project is intended to provide new information on species composition, distribution, abundance, seasonal variation, and habitat utilization among marine mammals and seabirds [...]

Purpose

Our three primary objectives were to (1) conduct aerial at-sea surveys of seabirds and marine mammals in shelf and slope waters off northern California, Oregon, and Washington and summarize species and seasonal at-sea densities (seabirds) and occurrance (marine mammals), (2) conduct a comparison with existing similar survey datasets off northern California, Oregon, and Washington, and (3) use telemetry information to validate and enhance aerial survey data for numerically abundant indicator species and certain resident breeding and non-resident migratory seabird species.
