Contours
The Study Area Contours feature class contains a compilation of bathymetric contours, or isobaths, from studies relevant to outer continental shelf (OCS) non-energy mineral resource (e.g. sand, gravel, shell) management. Many of these efforts were funded at least partially by the Bureau of Ocean Energy Management (BOEM) (formerly known as the Minerals Management Service). Attributes for each isobath include, but are not limited to, contour identifier, elevation (ft), vertical datum, and OCS Study Area ID. Additional information related to each isobath or group of isobaths is provided in the related tables within the MMIS geodatabase: Link Documents table - links tracklines to associated study report(s), Equipment table - list of specific equipment types used for data acquisition. The Study Area Contours layer and its related tables will be updated periodically as new and existing data are incorporated in to the MMIS geodatabase. NOTE: Bathymetric contours are a representation of the seafloor and their shape and respective values are dependent on the resolution of source data and the methods and datums used for acquisition, processing, and analysis. Please refer to the associated study area report for details related to data acquisition and processing.
