Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

New source rock data for the Mowry and Thermopolis Shales in the Wind River Basin, Wyoming New source rock data for the Mowry and Thermopolis Shales in the Wind River Basin, Wyoming
In 2020, the U.S. Geological Survey (USGS) assessed the potential for undiscovered, technically recoverable continuous (unconventional) oil and gas resources in the Mowry Shale in the Wind River Basin Province (Finn and others, 2021). To better characterize the source rock potential of the Mowry Shale and associated strata, 129 samples were collected from 45 wells from the well cuttings...

This data release documents the spatial and temporal variability of nutrients and related water quality parameters at high spatial resolution in the western and central portion of the Sacramento-San Joaquin River Delta of California, USA. The data set includes water residence time, nitrate, ammonium, phosphate, dissolved organic carbon, temperature, conductivity, dissolved oxygen...
30 Year (1990 - 2019) Annual Average Difference between Precipitation Potential Evapotranspiration 30 Year (1990 - 2019) Annual Average Difference between Precipitation Potential Evapotranspiration
This metadata record describes the 30 year (1990-2019) annual average difference between precipitation potential evapotranspiration in millimeters in geotiff format. The source data is based on the ClimGrid netcdf data for precipitation and temperature (Wieczorek and others, 2022). Units are millimeters.
Cold-weather air and subsurface temperature profiles of three different permeable pavements, Madison, Wisconsin, between 2014 and 2021 Cold-weather air and subsurface temperature profiles of three different permeable pavements, Madison, Wisconsin, between 2014 and 2021
Corrected and aggregated temperature data from the subsurface of three permeable pavement types [permeable interlocking concrete pavers (PICP), pervious concrete (PC), and porous asphalt (PA)] collected in Madison, Wisconsin between November 1 and April 30 (cold-weather periods), 2014-2021 are in this data release. Temperature data was corrected through removal of intermittent erroneous...
Sample details and near-real-time ED-XRF, grain size, and grain shape data collected during the November – December 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi Sample details and near-real-time ED-XRF, grain size, and grain shape data collected during the November – December 2022 eruption of Mauna Loa volcano, Island of Hawaiʻi
At 11:21 p.m. (Hawaii Standard Time [HST]) on November 27, 2022, Mauna Loa volcano on the Island of Hawaiʻi started erupting from fissures at its summit caldera, Mokuʻāweoweo. This was followed shortly afterwards by the opening of a segment of fissures in the direction of the Southwest Rift Zone. These were mostly within the structural boundary of the caldera, so their location is...
Regional Water Table (2018) in the Mojave River and Morongo Areas, Southwestern Mojave Desert, California Regional Water Table (2018) in the Mojave River and Morongo Areas, Southwestern Mojave Desert, California
Data for groundwater-levels measured in 707 wells during January-July 2018 by the United States Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water districts were compiled to construct a regional water-table shapefile for 2018. The regional water-table shapefile shows the elevation of the water table in and around the Mojave River and Morongo areas, in San...
Regional Water Table (2020) in the Mojave River and Morongo Areas, Southwestern Mojave Desert, California Regional Water Table (2020) in the Mojave River and Morongo Areas, Southwestern Mojave Desert, California
Data for groundwater-levels measured in 616 wells during water year 2020 (November 2019-June 2020) by the United States Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water districts were compiled to construct a regional water-table shapefile for 2020. The regional water-table shapefile shows the elevation of the water table in and around the Mojave River and...
Western Pond Turtle (Emys [Actinemys] marmorata) Observations at Point Reyes National Seashore and Golden Gate National Recreation Area Western Pond Turtle (Emys [Actinemys] marmorata) Observations at Point Reyes National Seashore and Golden Gate National Recreation Area
These data represent incidental observations of western pond turtles (Emys [Actinemys] marmorata) collected by the U.S. Geological Survey, Western Ecological Research Center, at Point Reyes National Seashore and Golden Gate National Recreation Area between 1993 and 2014. These data do not have associated survey effort, and are intended to represent incidental observations, rather than a...
Assessment of hydrologic alteration at 12-digit hydrologic unit code (HUC12) pour points in the southeastern United States, 1950 - 2009 Assessment of hydrologic alteration at 12-digit hydrologic unit code (HUC12) pour points in the southeastern United States, 1950 - 2009
Two methods of calculating hydrologic alteration were applied to modeled daily streamflow data for 9,201 12-digit hydrologic unit code (HUC12) pour points draining to the Gulf of Mexico (Robinson and others, 2020). The first method is a new modified method of calculating ecosurplus and ecodeficit called hydro change. For this project, ecosurplus and ecodeficit have been combined to...
