Data

In 2024, the U.S. Geological Survey, in cooperation with Riverside Energy Michigan, LLC, conducted an injection experiment to assess the potential for stimulating biogenic methane in the Mortensen A4-24 well which was completed in the Antrim Shale and located in Antrim County, Michigan, United States of America. Approximately 20 barrels (bbl) of produced water was pumped from the well...

The data set contains geochemical data for 1,524,014 rock, sediment, soil, and mineral samples collected by the U.S. Geological Survey within US state, territory or Economic Exclusive Zone (EEZ) boundaries, and analyzed from 1962 through 2023 either in the analytical laboratories of the Geologic Discipline of the USGS or by contract with commercial analytical laboratories. These data...

Geochemical data were generated and compiled for sedimentary rocks and bentonites deposited in the Cretaceous Western Interior Seaway from 15 drill cores and 1 outcrop spanning present-day Texas to Alaska. These data were collected to better understand Cretaceous source rocks and petroleum systems of the United States. These data accompany a manuscript that will be submitted to a journal...

This data release comprises major and trace element geochemical data from ninety (90) selected bedrock samples in support of the identification, discrimination, and correlation of map units in the Deep River and Essex quadrangles, Middlesex County, Connecticut. In data tables, the attributes “map_unit_symbol” and "map_unit_name" correlate the sample to the map unit in a planned bedrock...

This U.S. Geological Survey (USGS) data release contains data from stream water and groundwater samples collected in July through October 2024 at the Perigo Mine site in Gilpin County, northern Colorado. Data were collected as part of a study aimed at characterizing the local groundwater flow system in the hillslope hosting the mine’s draining crosscut tunnel, and identifying sources of...

Hydrothermal manganese oxide rocks were collected via dredge from the Tulaga Seamount, the flank of Ofu Island, and from Soso seamount in the Samoa hotspot region offshore American Samoa during the KM0506 cruise aboard the R/V Kilo Moana in April of 2005. Rocks were subsampled at USGS and analyzed for mineralogy by x-ray diffraction as well as sent to SGS laboratories, Canada for major...

Rocks were collected from the Escanaba Trough hydrothermal vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 on expedition TN403 aboard the R/V Thomas G. Thompson. Rocks were subsampled into Bulk and Rind samples at USGS and then sent to Activation Laboratories and Intertek for major and trace element geochemistry analysis.

Glacial and proglacial landscapes provide critical sources of water and solutes to downstream riverine and marine ecosystems. This dataset contains samples from the dominant landscape types in the Nellie Juan River basin, collected from surface streams, groundwater, rain, and snow. Water samples were also collected from streams near the Exit, Gulkana, and Kennicott Glaciers. Snow samples...

We present isotopic and geochemical data for several Archean and Paleoproterozoic metamorphic rocks in the Penokean orogen, USA. These data include new U-Pb and trace element analyses of apatite, titanite, and monazite; bulk rock major and trace element compositions; and whole rock and garnet Lu-Hf and Sm-Nd isotope compositions.

This data release contains the geodatabases and raster datasets used to construct the 2017 potentiometric‑surface maps and depth-to-water surfaces for the Nacatoch and Tokio aquifers. The datasets include: (1) groundwater‑level measurements and groundwater-altitude (GWA) from wells measured in 2017; (2) surface-water-altitude (SWA) from streamgages, if available, located within outcrop...

This is the primary repository for Geodetic Centroid (gCent) Catalog earthquake information, interferograms, and pixel tracking maps. This repository will be updated with new events as time permits and may not reflect the most up to date composition of the gCent catalog. Results included in this catalog, such as ShakeMap polygons, may differ from the operational products used and...

Saturn’s moon Titan is a focus of scientific investigation and future exploration by NASA’s Dragonfly mission. Its surface is covered by lakes of liquid ethane and methane, vast dune seas, and abundant organics sourced from photochemical reactions in its dense atmosphere. Over the course of its 13-year mission, NASA’s Cassini spacecraft’s Imaging Science Subsystem (ISS) acquired near...
