Sediment Thickness Data in the Deep-Sea Basins of the Bering Sea
A raster grid of sediment thickness in GeoTIFF format (BeringSeaBasins-SedimentThicknessGrid.tif) of the Aleutian, Bowers, and Komandorsky Basins was created by merging GeoTIFF grids of the Aleutian and Bowers Basins and of the Komandorsky Basin, provided in other sections of this data release. The raster grid file, along with a corresponding CSDGM FGDC-compliant metadata file, is provided in a zi
Marine Magnetic Anomalies of the Bering Sea and Pacific Ocean North of 35°N
The text file in CSV (comma-separated values) format contains marine magnetic data from 291 cruises in the Northern Pacific Ocean and Bering Sea. These data originate from two sources: 266 cruises from the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental Information (NCEI) Marine Trackline Geophysical Database (GEODAS) -- https://www.ncei.noaa.gov/access/me
Marine magnetic data from twelve cruises of Pioneer and Rehoboth in 1955 and 1956 off British Columbia, Washington, Oregon, and California
This shapefile contains total‐field marine magnetic data from eleven cruises of the USCGS ship Pioneer (OSS‐31) and one cruise from the USS Rehoboth (AGS‐50) in deep water off the west coast of the United States and southern British Columbia in 1955 and 1956. Magnetic anomalies are calculated with the latest definitive geomagnetic reference field (DGRF) included in the 12th Generation of the Inter
Detrital zircon geochronology and geochemistry data from the seafloor of the Bering Sea and adjacent river systems
This dataset archives geochronology and geochemistry measurements from detrital zircons collected from samples taken from the Bering Sea and its major feeder rivers.
Airborne Geophysical Survey Inventory of the Conterminous United States, Alaska, Hawaii, and Puerto Rico (ver. 5.0, April 2024)
This data release is a compilation of the locations of airborne geophysical surveys in the United States. The inventory documents public airborne geophysical surveys primarily flown by or contracted by the USGS from 1943 to present. In addition, surveys from the State of Alaska, Department of Natural Resources, Division of Geological and Geophysical Surveys (DGGS): Airborne GeophysWeb, the Bureau
Continental shelves as detrital mixers: U-Pb and Lu-Hf detrital zircon provenance of the Pleistocene–Holocene Bering Sea and its margins
Continental shelves serve as critical transfer zones in sediment-routing systems, linking the terrestrial erosional and deep-water depositional domains. The degree to which clastic sediment is mixed and homogenized during transfer across broad shelves has important implications for understanding deep-sea detrital records. Wide continental shelves are thought to act as capacitors characterized by t

Gravity surveys using a mobile atom interferometer
Mobile gravimetry is important in metrology, navigation, geodesy, and geophysics. Atomic gravimeters could be among the most accurate mobile gravimeters, but are currently constrained by being complex and fragile. Here, we demonstrate a mobile atomic gravimeter, measuring tidal gravity variations in the laboratory as well as surveying gravity in the field. The tidal gravity measurements achieve a

Three-dimensional basin and fault structure from a detailed seismic velocity model of Coachella Valley, Southern California
The Coachella Valley in the northern Salton Trough is known to produce destructive earthquakes, making it a high seismic hazard area. Knowledge of the seismic velocity structure and geometry of the sedimentary basins and fault zones is required to improve earthquake hazard estimates in this region. We simultaneously inverted first P wave travel times from the Southern California Seismic Network (3

gravmagsubs: Gravitational and magnetic attraction of 3-D vertical rectangular prisms
gravmagsubs is a software package for the R language that provides tools for forward modeling gravity and magnetic anomalies from 3-D right rectangular prisms. The gravity anomaly is defined as the vertical component of gravitational acceleration, while the magnetic anomaly includes the effects of both induced and remanent magnetization. The package can model the total anomaly from a collection
