Cooperative National Geologic Map: Pre-Quaternary geology Cooperative National Geologic Map: Pre-Quaternary geology
The USGS National Cooperative Geologic Mapping Program (NCGMP) was directed by Congress to create a new geologic map of the United States” by “bring[ing] together detailed national and continental-resolution 2D and 3D information produced throughout the Survey and by federal and state partners” (House Report 116-100). To fulfill this goal, the NCGMP created a map synthesis engine...

Airborne magnetic and radiometric data acquired over parts of Cochise, Graham, Greenlee, Pima, Pinal, and Santa Cruz Counties, Arizona Airborne magnetic and radiometric data acquired over parts of Cochise, Graham, Greenlee, Pima, Pinal, and Santa Cruz Counties, Arizona
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey of the Arizona Porphyry Copper Belt in southeastern Arizona. The airborne survey was funded by the Earth Mapping Resources Initiative. NV5 Geospatial, in collaboration with EDCON-PRJ, Inc., acquired high-precision airborne magnetic and radiometric data from November 15, 2023...
Relationships Among Agricultural Data Sources of Conservation Practice Implemented in the Chesapeake Bay Watershed Relationships Among Agricultural Data Sources of Conservation Practice Implemented in the Chesapeake Bay Watershed
Through data sharing agreements with Federal and State agencies, the U.S. Geological Survey (USGS) collects time-series of environmental management practice data to inform studies that guide resource management decisions. These data include agricultural conservation practices, best management practices (BMPs), and pollution control strategies in the Chesapeake Bay watershed. This data...
Sediment grain-size data from the Klamath River estuary, California Sediment grain-size data from the Klamath River estuary, California
This data release includes grain-size measurements on sediment samples collected from the substrate surface and uppermost 10 cm of sediment deposits in the Klamath River estuary, northern California. Samples were collected using a BMH-60 bed-material sampler deployed from a boat, or by hand trowel from subaerial or shallow-water (less than 0.5 m water depth) regions along the estuary...
In situ Geochemical Data for Detrital and Porphyry-Related Magnetite from the Taurus Porphyry Cu Deposit and Environs, Alaska, United States In situ Geochemical Data for Detrital and Porphyry-Related Magnetite from the Taurus Porphyry Cu Deposit and Environs, Alaska, United States
This data release comprises geochemical point analyses of magnetite by electron probe microanalyzer (EPMA) and sample imagery acquired by a combination of scanning electron, reflected light, and transmitted light microscopy. Analyzed elements include Fe, Ti, Al, Mn, Mg, V, Si, Ni, Cr, and Ca. Samples are from the Taurus porphyry Cu-Mo(-Au) deposit in the Yukon-Tanana upland of eastern...
(U-Th)/He Dates of Detrital Magnetite from Streams Draining the Taurus Porphyry Cu Deposit, Alaska, United States (U-Th)/He Dates of Detrital Magnetite from Streams Draining the Taurus Porphyry Cu Deposit, Alaska, United States
This data release contains 54 (U-Th)/He dates acquired from detrital magnetite in stream sediments adjacent to the Taurus Porphyry Cu-Mo(-Au) deposit in eastern interior Alaska's Yukon-Tanana Upland. Measured parameters include Helium-4, Uranium-238, Thorium-232, measured grain geometry factors, and all associated analytical uncertainties. Final (U-Th)/He dates along with uncertainties...
Length and mass measurements for a clutch of Burmese python hatchlings from southern Florida including observations of multi-embryo eggs Length and mass measurements for a clutch of Burmese python hatchlings from southern Florida including observations of multi-embryo eggs
Demographic and morphological data from an adult female Burmese python and a clutch of hatchlings produced July 2024 in Big Cypress National Preserve in southern Florida.
Seagrass map, Cat Island, Mississippi, 2023 Seagrass map, Cat Island, Mississippi, 2023
This product depicts the spatial coverage of seagrass beds from 0.5-m color-infrared orthoimagery for Cat Island, Mississippi from early fall of 2023. Specifically, the map includes presence and absence of seagrass beds within a potential seagrass extent that was based on topobathymetric data. A minimum mapping unit of 4 square meters was used for this mapping effort. We did not have...
