All Data

This U.S. Geological Survey (USGS) data release provides phytoplankton data collected from the Kansas River and tributaries, during July 2012 through June 2023. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources in the West Greenland-East Canada Province. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas...

USGS Evapotranspiration estimates provide useful information for a range of land use applications, from calculating a basin’s water budget to assessment of water consumption for crop yield and drought monitoring. This USGS data release is a result of using the OpenET Google Earth Engine (GEE) implementation of the USGS EROS Operational Simplified Surface Energy Balance (SSEBop)...

This data release contains concentration and isotope-dilution standard (IDS) recovery data from individual samples that are summarized and interpreted in the U.S. Geological Survey (USGS) Techniques and Methods (T&M) Report "Determination of Per- and Polyfluoroalkyl Substances in Water by Direct Injection of Matrix-Modified Centrifuge Supernatant and Liquid Chromatography-Tandem Mass...

This dataset consists of one table containing whole-rock geochemistry data for 251 igneous, metamorphic, and mineralized (metasomatic) rocks from various locations across Alaska in support of mineral assessments of critical minerals and transboundary watersheds. The samples were collected mainly between 2019 and 2023, and all materials were analyzed by ALS Global, between 2019 and 2023...

This dataset contains results from three stratigraphic sections of the Hue Shale located in and adjacent to the Arctic National Wildlife Refuge in northeastern Alaska. Sample heights were measured with a tape measure in continuous successions. Zircon grains from volcanic ashes were analyzed via laser ablation at the University of California, Santa Barbara (UCSB) using a Photon Machines...

Roads and bridges are vulnerable to a range of stressors, such as flooding, heat waves, and other extreme events. The probability of these stressors impacting roads and bridges cannot be exactly calculated due to various uncertainties related to the scientific understanding of future environmental conditions. Resilient design methods find ways to account for the uncertainty in various...

Streamflow in a river can be used to calculate loads of constituents of concern in rivers but obtaining streamflow data using traditional streamgaging techniques in ephemeral channels can be cost prohibitive. Because of the remote location and infrequent flow occurrences, collecting paired stage-streamflow measurements for sufficient flow events during a 2-year study to develop a rating...

This data release presents data and calculations for morphometric parameters, median and maximum unfiltered concentrations used in statistical analyses, and stream lengths through geologic units that contain elevated concentrations of constituents of concern used for the publication, "Morphometric and geologic characterization with statistical correlations for 33 tributary drainage...

This data release contains nearshore bathymetry measurements collected at Point Barrow, Alaska in July 2022. These data were collected as part of an effort to monitor and forecast coastal flooding and erosion. They are also intended for reuse by scientists, managers, and the general public.

Bulk organic geochemical, major and trace element, and mineralogical data have been collected for core and cuttings samples of the Eocene Green River Formation from thirty-four wells in the Uinta Basin of Utah. The samples were collected from the U.S. Geological Survey Core Research Center in Denver, CO and the Utah Core Research Center in Salt Lake City, UT and represent multiple...

Variability in river discharge, particularly very high flow and low flow conditions, has far-reaching environmental and economic consequences. The retention of water in surface storage, concentrated in lakes, ponds, wetlands, floodplains, and temporary water in flood prone areas, can potentially contribute to flow generation and flood regulation. However, the impact of surface water...
