U-Pb Isotopic Data and Ages of Detrital Zircon and Volcanic Zircon Grains from the Torok and Nanushuk Formations, Arctic Alaska, 2021 U-Pb Isotopic Data and Ages of Detrital Zircon and Volcanic Zircon Grains from the Torok and Nanushuk Formations, Arctic Alaska, 2021
This dataset contains U-Pb isotopic data and associated ages of zircon grains from 27 sedimentary samples and one volcanic ash sample from the Cretaceous Torok and Nanushuk Formations. Seven samples were collected from outcrop and 21 samples were collected from archived core material from oil exploration wells on the North Slope of Arctic Alaska. Zircon grains were analyzed at the...

Underwater temperature on off-shore coral reefs of the Florida Keys, U.S.A. Underwater temperature on off-shore coral reefs of the Florida Keys, U.S.A.
The U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies project provides science that helps resource managers tasked with the stewardship of coral reef resources. Coral reef organisms are very sensitive to high and low water-temperature extremes. Therefore, it is critical to precisely know water temperatures experienced by corals and associated plants and animals that live in the...
Dataset for mineral resource inventory of North Dakota Dataset for mineral resource inventory of North Dakota
This data release contains the geospatial resources that were used by the USGS to compile the mineral resource inventory for the state of North Dakota, developed by the Mineral Resource Program (MRP) staff of the U.S. Geological Survey (USGS) at the request of the Bureau of Land Management (BLM). The mineral resources inventory was published as a USGS open-file report and can be accessed...
Attribution of Chessie BIBI and fish sampling data to NHDPlusV2 Catchments within the Chesapeake Bay Watershed Attribution of Chessie BIBI and fish sampling data to NHDPlusV2 Catchments within the Chesapeake Bay Watershed
This data release links fish survey data from a suite of programs in the Chesapeake Bay watershed as well the benthic macroinvertebrate sites included in the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) developed by the Interstate Commission on the Potomac River Basin (ICPRB) and available from the Chesapeake Bay Program. The data set contains site name, survey...
