Reflectance data from vitrinite and bituminite in the Kimmeridge Clay Formation supporting the ICCP Identification of Dispersed Organic Matter Working Group round robin exercises from 2016 to 2020 Reflectance data from vitrinite and bituminite in the Kimmeridge Clay Formation supporting the ICCP Identification of Dispersed Organic Matter Working Group round robin exercises from 2016 to 2020
Three round robin exercises (RRE) aimed at characterizing bituminite and testing the reproducibility of random vitrinite (VRo %) and bituminite (BitRo %) reflectance measurements of the Kimmeridge Clay Formation were conducted in 2016, 2018, and 2020. This work was conducted by the Identification of Dispersed Organic Matter Working Group (IDOM WG) of the International Committee for Coal...

Tiltmeter data on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory from July 1, 2025 to present with 60-day latency. These data are collected by the USGS Hawaiian Volcano Observatory. This dataset will be updated as new tiltmeter data are collected and approved with 60-day latency.
Data supporting a study using low-temperature hydrous pyrolysis as a method of determining the quantity and quality of oil retained in thermally mature, Mowry Shale, Powder River Basin, Wyoming Data supporting a study using low-temperature hydrous pyrolysis as a method of determining the quantity and quality of oil retained in thermally mature, Mowry Shale, Powder River Basin, Wyoming
The Cretaceous Mowry Shale is a prolific source rock in numerous Laramide basins and operators have recently increased research activity testing the Mowry as an unconventional source-rock resevoir in the Powder River Basin (PRB). Despite this recent increase in research activity, much work remains on characterizing the quantity and quality of oil retained in thermally mature Mowry Shale...
GIS Data for Geologic Map of the Craig 1 Degree x 2 Degrees Quadrangle, Northwestern Colorado GIS Data for Geologic Map of the Craig 1 Degree x 2 Degrees Quadrangle, Northwestern Colorado
This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the Craig 1 degree x 2 degrees quadrangle, northwestern Colorado (Tweto, 1976). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in the USGS Miscellaneous...
Spawning Whitefish and Invasive Mussels (SWIM) project supporting data collected in the Great Lakes, 2024-2025 overwinter physics and chemistry on spawning reefs Spawning Whitefish and Invasive Mussels (SWIM) project supporting data collected in the Great Lakes, 2024-2025 overwinter physics and chemistry on spawning reefs
This dataset records physical (photosynthetically available radiation, currents, wave action, and temperature) and physicochemical (specific conductivity, turbidity, pH, phycocyanin, chlorophyll, and dissolved oxygen) data from sensors moored during the winter season of 2024-2025 at two lake whitefish spawning reefs – Good Harbor Bay in Lake Michigan and Thunder Bay in Lake Huron. The...
Model and Lidar derived Snow and Canopy information at the sub-watershed scale for Southwestern Colorado Model and Lidar derived Snow and Canopy information at the sub-watershed scale for Southwestern Colorado
Snow and Canopy data for a forest snow web interface. The USGS developed a new snow model that better represents forest-snow interactions and the results are displayed in an interactive web-platform. This platform allows an end user to query the results to better understand how changing forests may impact snow water resources within the model domain. These data are from existing...
Projected proportional change in population density for American pronghorn under future climate scenarios in the U.S. Southwest Projected proportional change in population density for American pronghorn under future climate scenarios in the U.S. Southwest
Projected proportional change in American pronghorn (Antilocapra americana) population density in the U.S. Southwest under future climate scenarios. Projections are available for all combinations of three future time periods (2021-2050 ["2030s"], 2041-2070 ["2050s"], and 2061-2090 ["2070s"]), two emissions scenarios (RCP4.5 and RCP8.5), and two statistical models (means and extremes)...
Data to determine new age constraints on the Ediacaran Salt Range Formation of Pakistan Data to determine new age constraints on the Ediacaran Salt Range Formation of Pakistan
The Neoproterozoic–Early Cambrian Salt Range Formation (SRF) of Pakistan is a sequence of salt, gypsum, marl, dolomite, fine-grained siliciclastic rocks (shale, siltstone and sandstone), oil shale, and hydrothermally altered extrusive volcanics. The formation occurs in the Salt Range physiographic feature, a mountain range rising 750 to 1000 m above alluvial plains of northwestern...
Projected proportional change in wildlife population measures for Scaled Quail, Gambel's Quail, and Gunnison's prairie dog under future climate scenarios in the U.S. Southwest Projected proportional change in wildlife population measures for Scaled Quail, Gambel's Quail, and Gunnison's prairie dog under future climate scenarios in the U.S. Southwest
The dataset includes 36 raster files of predicted proportional change in wildlife population measure for different combinations of species, statistical model, time period, and emissions scenario. This collection includes all 36 possible combinations of three species (Gambel's Quail, Scaled Quail, and Gunnison's prairie dog), three future time periods (2021-2050, 2041-2070, and 2061-2090)...

The monitoring of Lake Saint Clair Metropark beach involved several types of data collection. This data release includes data sets for the counts of avian species (gulls and Canada geese) and data on water fluxes between surface water and groundwater measured during recreational seasons of 2021, 2022, and 2023.
Nearshore substrate, macrophyte, invertebrate, and clam data collected at field sites pre- and post-installation of a clam garden in the Pacific Northwest (2021-2025) Nearshore substrate, macrophyte, invertebrate, and clam data collected at field sites pre- and post-installation of a clam garden in the Pacific Northwest (2021-2025)
The Swinomish Indian Tribal Community (SITC) is reviving an ancient mariculture practice by installing the first known present-day clam garden in the United States. Clam gardens are intertidal features modified by coastal Indigenous people (e.g., creating intertidal terraces to alter beach slope and substrate) to enhance clam habitat for optimal shellfish production. Nearshore substrate
