This document provides an assessment of the status of ecological condition in coastal-ocean waters along the U.S. continental shelf, from the Strait of Juan de Fuca, WA to the Mexican border, based on sampling conducted in June 2003. The project was a large collaborative effort by the U.S. Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), and West Coast States. The western National Coastal Assessment (NCA-West) program of EPA, in conjunction with the NOAA National Ocean Service (NOS), conducted an assessment of the status of ecological condition of soft sediment habitats and overlying waters along the western U.S. continental shelf, between the target depths of 30 and 120 m, during June 2003. This study showed no major evidence of extensive biological impacts linked to measured stressors.
