NOAA Office for Coastal Management Benthic Habitat Data, Willapa Bay, Washington, 1995 (NCEI Accession 0089466)
These data are benthic study GIS shapefiles (.shp, .shx, .prj) with associated .dbf attribute tables and specific Federal Geographic Data Committee metadata. A generalized browse graphic was generated at the NODC and included with these data.
In June 1995, the Columbia River Estuary Study Taskforce (CREST) acquired 295 true color aerial photographs (1:12,000) of Willapa Bay, Washington, from the State of Washington Department of Transportation (WDOT), suitable for the interpretation of submerged rooted aquatic vascular plant populations. In August 1995, field surveys were conducted by a team composed of staff from Oregon State University, CREST, and the Washington Department of Natural Resources, for spectral signature development and verification as well as habitat observation. The submerged plant populations were interpreted and mapped from the photographs and transferred onto State of Washington 1:12,000 Orthophoto maps (USGS 7.5 foot quadrangle).
The interpretations were digitized into a geographic information system (GIS) for the creation of a habitat polygon map. All interpretation, digitization and photography acquisition were according to stringent parameters detailed in the Coastal Change Analysis Program (C-CAP) Protocol (NMFS Technical Document 123). Two datasets were used as ancillary information to complement the interpreted habitat polygons. In 1996, color aerial videography was obtained from WDOT for post mapping verification and accuracy assessments. Marine Resources Consultants, Inc. and the University of Washington collected videography from 29 underwater transects to verify the deep-water edge of selected seagrass beds in the southern portion of the bay. The date, time, geographic coordinates and depth were updated every 2 to 4 seconds and recorded directly on the videotape images. Latitude and longitude were provided by a differentially corrected global positioning system (GPS).
The initial presence/absence map of SAV produced by CREST was later segmented by depth to discriminate between two very different seagrass communities and support field accuracy assessment. Final field verification of the data by personnel from CREST and the NOAA Coastal Services Center (now the NOAA Office for Coastal Management) was conducted in the Summer of 1997. The benthic data is classified according to the System for Classification of Habitats in Estuarine and Marine Environments (SCHEME). This system is fully described in Development of a System for Classification of Habitats in Estuarine and Marine Environments (SCHEME) for Florida, Report to U.S. EPA - Gulf of Mexico Program, Florida Fish and Wildlife Conservation Commission, Florida Marine Research Institute.

Supplemental Information | These data were formerly titled at the NCEI as NOAA Coastal Services Center Coastal Remote Sensing Program C-CAP (NOAA Coastal Change Analysis Program) Benthic Habitat Data, Willapa Bay, Washington, 1995 (NODC Accession 0089466). The dataset title was changed in October 2015 to reflect correctness and currency. Browse graphics for these data produced by the NODC were designed to provide a rapid overview of the data and facilitate user searches. They do not contain all data attributes of the data sets. GIS software is suggested when viewing or working with these data for maximum usability and performing data analyses. A land mask is not provided for these data. Suggested shorelines are NOAA's Medium Resolution Shoreline downloadable at //coastalgeospatial.noaa.gov/data_gis.html and the GSHHS - A Global Self-consistent, Hierarchical, High-resolution Shoreline Database downloadable at http://www.ngdc.noaa.gov/mgg/shorelines/gshhs.html. |
