New Jersey Department of Environmental Protection, New Jersey Geological SurveyGravity anomalies are produced by density variations within the rocks of the Earth's crust and upper mantle. Mapping of these density variations is the primary use of gravity anomalies. Bouguer Anomalies of New Jersey is a GIS shapefile of bouguer gravity contours (lines) at 1 milligal intervals. The contours are based on gravity data in New Jersey and vicinity. The New Jersey contours were clipped at the state outline.The bouguer anomalies in New Jersey range from a low of -58 milligals to a high of +37milligals.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/342c465e13744d1097caf8b6dece5cd5_10engNew Jersey Department of Environmental Protection's (NJDEP) Bureau of GISPublicGravity Anomalies (1 mgal) in New Jersey [New Jersey]Web servicesNew JerseyLast Modified: 2021-11-08
