Through a partnership between the National Oceanic and Atmospheric Administration's (NOAA) Office of Coast Survey (OCS), NOAA's National Marine Sanctuary Program (NMSP), and NOAA's Office of Marine and Aviation Operations (OMAO), high resolution bathymetry (HRB) was collected on various opportunistic occasions during the months of October from 2001-2004 in the Olympic Coast National Marine Sanctuary (OCNMS).

The Olympic Coast National Marine Sanctuary (OCNMS) continues to invest significant resources into seafloor mapping activities along Washington's outer coast. Results from these annual mapping efforts offer a snapshot of current ground conditions, help to guide research and management activities, and provide a baseline for assessing the impacts of various threats to important habitat. This report provides a description of the mapping efforts and the results of the image classification procedure for each of the areas surveyed in 2004 and 2005.
