THE PUGET SOUND AMBIENT MONITORING PROGRAM: RECENT TRENDS IN BIOTIC AND HABITAT PARAMETERS
image
The Puget Sound Ambient Monitoring Program (PSAMP) is a coordinated monitoring effort implemented by a team of investigators from five state agencies, three federal agencies, and the largest county government in the Puget Sound basin. Through PSAMP, data on marine and fresh waters, fish, sediments, and shellfish in Puget Sound have been collected since 1989; surveys of nearshore habitat have been conducted since 1991; and studies of the populations of and contamination in marine birds and mammals have been conducted since 1992. The purpose of PSAMP is to document natural and anthropogenic change in the physical and biotic components of ecosystems within the Puget Sound basin. A survey of status and recent trends in several PSAMP datasets will be presented: distribution in submerged aquatic vegetation, including invasive Spartina; fecal coliform, nutrient and dissolved oxygen patterns in fresh and marine waters; population data for nine marine bird species; contaminant loadings in Dungeness Crab and six fish species; metal and organic sediment contamination. Future directions for monitoring within Puget Sound will also be addressed.
