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 within the outer continental shelf of the northern California Current System (NCCS). The NCCS supports abundant populations of seabirds and marine mammals, but comprehensive aerial surveys have not been conducted at all during certain months (i.e., winter) or were conducted two to four decades ago.

During 2011 - 2012, the USGS Western Ecological Research Center completed the Pacific Continental Shelf Environmental Assessment (PaCSEA) aerial survey project. PaCSEA included replicated surveys to quantify seabird and marine mammal distributions over the continental shelf and slope domains from shore to the 2000-meter (m) isobath along 32 broad-scale transects and within six focal area surveys from Fort Bragg, California through Grays Harbor, Washington. This is the first comprehensive, large-scale, multiseasonal aerial survey conducted in this region since the early 1980s and 1990s.
