This dataset supports the Bureau of Ocean Energy Management's (BOEM) Marine Minerals Program (MMP) mission of managing non-energy minerals (primarily sand and gravel) on the OCS. The data and information provided in this dataset helps facilitate these management efforts via the identification of potentially sensitive (e.g. archaeological/cultural) areas, submerged infrastructure, or unidentified objects that should be avoided during dredging operations in their immediate vicinity. |

The Magnetic Survey Contours feature class is a collection of magnetic contours derived from magnetometer surveys conducted as part of geophysical cultural/archaeological resource investigations in the immediate vicinity of offshore borrow areas and dredged material conveyance corridors. These contours help identify objects of cultural/archaeological significance, submerged infrastructure (e.g. pipelines), or unidentified debris that might affect the ability of the Bureau of Ocean Energy Management (BOEM) and its partners and/or contractors to perform non-energy marine mineral acquisition tasks. The attribute table of this feature class contains summary information such as date, project name, and information related to data acquisition (magnetometer type, sensor configuration, amplitude, etc.). The associated survey report can be accessed via the related Link Documents table. This dataset will be updated regularly as new and existing data are incorporated in to the Marine Minerals Information System geodatabase. |
