Parent Layer: Seabed Features

Name: Magnetic Anomaly Pnt

Display Field: ProjectName

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: The Magnetic Anomaly Point feature class is a collection of points representing the location of man-made ferrous objects on or below the seabed that were identified during magnetometer surveys conducted as part of geophysical cultural/archaeological resource investigations in the immediate vicinity of offshore borrow areas and dredged material conveyance corridors. The points may represent 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 pertaining to each anomaly, including (but not limited to) anomaly ID, date, x/y coordinates, project name, and information related to data acquisition (magnetometer type, sensor configuration, amplitude, duration, signal type, 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.
