The Study Area Tracklines layer is a compilation of tracklines of vessels conducting geophysical surveys or other data acquisition efforts (e.g. trawling surveys, observational video transect, etc.) 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 trackline include, but are not limited to, cruise/project ID, line ID, date, time, type(s) of data collected, and links to related content or imagery. The attributes also indicate whether or not the raw data are available for request from the BOEM's Marine Minerals Program. Additional information related to each trackline 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 along each trackline. The tracklines layer and its related tables will be updated periodically as new and existing data are incorporated in to the MMIS geodatabase. |
