The Mississippi River Valley alluvial aquifer (MRVA) in eastern Arkansas is a major source of groundwater for public, industrial, agricultural, and aquaculture uses. Estimated withdrawals from the MRVA increased from 1,063 million gallons per day in 1965 (Halberg and Stephens, 1966) to 7,252 million gallons per day in 2005 (Holland, 2007). Potentiometric-surface maps, which represent the...

This database contains published strontium isotopic ratios (87Sr/86Sr) and associated sample collection data for strontium dissolved in environmental waters for the United States (conterminous, Hawaii, Alaska, and coastal seawater). Samples included in this version were collected and analyzed between 1963 to 2022.

As part of the Breton Island Post Construction Monitoring project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a nearshore geophysical survey in August 2024 to map the borrow site created during the Breton Island, Louisiana (LA) restoration effort that began in December 2020. The restoration effort was part of the Deepwater...

The Salinity and Temperature Data for South Florida Estuarine Mollusks (1994-present) database contains salinity and temperature readings from modern monitoring sites where live mollusks were observed during fieldwork performed from 1994 to present, salinity and temperature summary statistical data for each species, and location information about the sites where the monitoring data were...

The Willwood Working Group Two of Wyoming conducted an experimental sediment release from Willwood Dam from April 11-13, 2023. The experiment involved opening sluice gates at the base of Willwood Dam to draw down the dam pool which created energy to mobilize sediment deposits behind the dam. The U.S. Bureau of Reclamation released up to 4,000 cubic feet per second from Buffalo Bill Dam...

This U.S. Geological Survey (USGS) data release includes whole-rock major, trace, and rare earth element geochemical data, whole-rock and mineral Nd-Pb-Sr isotopic data collected by thermal ionization mass spectrometry (TIMS), and uranium-lead isotopic data collected by Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods that characterize the Mountain Pass Rare...

The bedrock geologic map database of the Woodstock quadrangle consists of highly deformed metasedimentary rocks of the Central Maine trough, including the Silurian Rangeley and Perry Mountain Formations and the Devonian Littleton Formation. The central, northern, and eastern parts of the quadrangle are underlain by the oldest rocks in the area, the Rangeley Formation. In the southwest...

The database for the Buckner 7.5-minute quadrangle straddles three terrane boundaries in the Piedmont Physiographic Province in central Virginia: the Chopawamsic terrane, the Elk Hill Complex, and the Goochland terrane. In much of the map area, the Elk Hill Complex separates the Chopawamsic and Goochland terranes. Rocks of the Chopawamsic terrane include Ordovician metavolcanic and...

Given the rapid expansion in the demand for mineral commodities that underpin worldwide economic growth and technological advancement, information regarding expected country-level mine production and production capacity is becoming increasingly important. In particular, production capacity can limit future supply, depending on how rapidly that capacity is able to expand. This World...

On August 24, 2021, the U.S. Geological Survey conducted a high-resolution seismic survey between two strong-motion recording stations located at the Veterans Affairs Medical Center (VAMC) in the City of Menlo Park, San Mateo County, California. The stations are National Strong Motion Project Station (NSMP) 1849 in VAMC building 332 and NSMP Station 1870 in VAMC building 334. The primary...

This dataset consists of tabular data of observed streamflow, URL links to timelapse images, and deep learning model predictions for 11 sites in western Massachusetts. The dataset also includes a record of annotation data used to train the deep learning models. This data release is supporting information for an associated journal article describing the data collection, development of the...

A modified marine radar was deployed on the National Oceanic and Atmospheric Administration research vessel, Gordon Gunter, during the fall of 2023 and 2024 as it transected the Gulf of America conducting benthic surveys. The radar collected data on avifauna (and flying animals generally) within a couple kilometers of the vessel during a portion of the fall migration. Data collected can...
