Describes collection of high resolution bathymetric data in the Olympic Coast National Marine Sanctuary by the NOAA ship Rainier during 2001-2004, using multibeam echosounders. Discusses how video, bathymetry data, sediment samples, and backscatter imagery were integrated to describe the geological and biological habitat, and how the data can be used with a GIS for display, query, and analysis. These survey operations were conducted through a partnership between NOAA's Office of Coast Survey (OCS), NOAA's National Marine Sanctuary Program (NMSP), and NOAA's Office of Marine and Aviation Operations (NMAO).

The Olympic Coast National Marine Sanctuary's "objectives for the survey effort were three-fold: 1) to obtain existing conditions of the nearshore bathymetry and intertidal zone along a select portion of shoreline that is not ascertainable through ship-based acoustic data acquisition techniques due to hazardous surf conditions, 2) to assess the performance of [airborne LIDAR bathymetry] technology along both exposed and unexposed stretches of coastline, and 3) to vertically transform the ALB data and assess agreement with existing shallow water multibeam bathymetry data collected in the same area."

Describes Olympic Coast National Marine Sanctuary's habitat mapping program to characterize seafloor substrates within its jurisdictional boundaries. Side scan sonar images, video, bathymetry data and sedimentary samples were used to describe geological and biological aspects of habitat. Geographic information systems can be used to analyze the data, in support of conservation efforts for the area's groundfish stocks.

"The Olympic Coast National Marine Sanctuary (OCNMS) continues to invest significant resources into seafloor mapping activities along Washington's outer coast (Intelmann and Cochrane 2006; Intelmann et al. 2006; Intelmann 2006). 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."
