Beginning in 1999, EPA Region 10, ORD and the States have conducted probability surveys of coastal waters. These surveys apply EMAP’s probability design and ecological indicators to an integrated and comprehensive coastal monitoring program. Water column measurements are combined with information about sediment characteristics and chemistry, benthic organisms, and data from fish trawls to describe the current estuarine condition.

The first year’s effort (1999) constituted an assessment of the condition of the small estuarine systems (< 250 km2) in the States of Oregon and Washington. In 2000, Coastal EMAP completed its estuarine assessment with surveys of the large estuarine systems - Puget Sound and Columbia River. In 2001 Oregon collected additional data from the small estuaries outside of the Columbia system. South Central Alaska, including Cook Inlet and Prince William Sound, and the intertidal areas of the Oregon, and Washington were surveyed in 2002. In 2003, Coastal EMAP sampled the offshore areas of the Oregon, and Washington. The 2004 sampling effort revisited the estuarine systems surveyed in 1999 and 2000, and will sampled Southeast Alaska. The estuary and open coastal areas of the Aleutian Islands in Alaska were sampled in 2005-2007. The next survey planned is for 2010 and it will once again revisit the estuarine systems surveyed in 1999/2000 and 2004.
