Name: Study Area Survey Data - Backscatter/Sidescan Sonar

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The Study Area Survey Measurements Mosaic Dataset is a collection of bathymetry and backscatter rasters compiled from numerous site-specific, field-oriented studies in the Outer Continental Shelf (OCS). The studies are fully or partially funded by BOEM, an agency within the U.S. Department of the Interior. They consist of sand resource reconnaissance surveys, sand placement surveys, research on baseline benthic ecological conditions, and environmental impact investigations pertaining to the potential effects of dredging operations on the physical, chemical, and biological environment. These data span several decades of published research and were collected and processed using a variety of instruments and software. Please refer to individual raster attributes and the associated study report(s) for details related to data acquisition and processing. This dataset will be updated regularly as new and existing data are incorporated into the Marine Minerals Information System (MMIS) geodatabase. Area covered: U.S. OCS (primarily 3nm to 12nm offshore). Each raster in this mosaic is stored in its native projection. The rasters are projected into NAD83 on the fly by the MMIS WebViewer. Should a user export a raster from the database, or download it through the viewer, the downloaded file will be in the native projection.
