Airborne magnetic data are provided here as part of the data release, "Airborne magnetic and radiometric survey, Munsungun Region, northern Maine, 2021." This website includes the processed aeromagnetic data provided in an ascii .csv file and a geoTIFF image showing the anomalous magnetic field. The contractor report is available on the parent page. Data for this survey were collected and processed by Sander Geophysics under contract with the USGS as part of the Earth Mapping Resources Initiative (Earth MRI) using a fixed wing aircraft with a magnetometer mounted in a tail stinger and a fully calibrated gamma ray spectrometer, data were collected along northwest-southeast flight lines spaced 250 meters (m) apart...

Airborne radiometric data are provided here as part of the data release "Airborne magnetic and radiometric survey, Munsungun Region, northern Maine, 2021." This website includes the processed aeroradiometric digital flight line data (gamma spectrometry for K, U and Th) provided in an ascii .csv file and geoTIFF images showing a ternary image of relative K, U and Th and individual K, U, and Th values. Radiometric spectra are provided in ascii and binary formats within the contractor package on the parent page. The contractor report is also available on the parent page. Data for this survey were collected and processed by Sander Geophysics under contract with the USGS as part of the Earth Mapping Resources Initiative...

This topobathymetric digital elevation model (TBDEM) represents the topography and bathymetry for the Eastern Shore peninsula of Virginia, including Accomack and Northampton counties, and extending into Worcester and Somerset counties in Maryland. The TBDEM has a horizontal grid spacing of 1 meter and vertical units of 1 (integer) centimeter. This dataset combines U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center Coastal National Elevation Database topobathymetric DEM (CoNED TBDEM) data with data from the USGS Northern Atlantic Coastal Plain DEM, the latter of which were used to extend the bathymetric surface further offshore. In some areas, National Map 3D Elevation Program (3DEP)...
