All Data

Flood-frequency analyses were conducted for three streamgages operated by the U.S. Geological Survey (USGS) in the Black River basin of southeastern Missouri (MO) and northeastern Arkansas (AR): 07064000, Black River near Corning, AR; 07068000, Current River at Doniphan, MO; and 07069000, Black River at Pocahontas, AR. Results from the analyses will be used for design purposes by the...

These data describe the demographic composition of Common Terns at a newly identified staging area on the Patuxent River Naval Air Station and evaluates the importance of this location to the local breeding population. Specifically, we sought to identify the number of individuals using this potential staging area, the origins of those individuals, and the relative importance of this...

Each year from 2021-2024, teams from the US Geological Survey and Virginia Tech studied 30 streams with a targeted gradient of land use and conservation practices across the Chesapeake Bay Watershed. The four years of the study cover the following geographic areas and land use characteristics: -Shenandoah Valley and Ridge pasture -Delmarva row crop -Pennsylvania and Maryland Piedmont...

This data release contains a dataset of geospatial and tabular data used in support of a flood-frequency study of urban streams in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina (Wagner and Ladd, 2026). The dataset includes data used in the development of generalized least-squares (GLS) regression equations for predicting streamflows at ungaged...

These data were collected to assess the occurrence of foothill yellow-legged frogs (Rana boylii) in 2022, one year after the 2021 Dixie Fire in northeastern California, USA. The data included herein are those required to replicate the occupancy analysis presented in the manuscript, cited in the larger work. Additional site data are included in the manuscript itself.

This dataset includes eighteen years of emissions and sequestration estimates (2005-2022) in two separate tables. Table 1 includes the greenhouse gas emissions from the combustion and extraction of fossil fuels on Federal mineral lands. Table 2 is the emissions and sequestration from ecosystem processes on Federal surface lands. The fossil fuel related estimates include the greenhouse...

The water balance equivalence (WABE) method for reducing biases from remote sensing-derived evapotranspiration (RSET) products for large area applications is proposed and implemented across eight-digit hydrologic unit code (HUC8) basins in the conterminous United States (CONUS). These data support the findings of the WABE method that includes climatology (2002-2015 average) observed...

This metadata record describes a series of data sets of climate and land-use/land-cover features (provided in parquet file format) linked to NHDPlus Version 2.1’s (NHDPlusV2) stream segments, their associated catchments and their upstream watersheds within selected regions in the conterminous United States. All data can be linked to NHDPlusV2 using the COMID field in these tables and the...

Quaternary ammonium compounds (QAC) are used in many commercial and household disinfection products. A method was developed to measure QAC occurrence in water discharged from three wastewater treatment plants during 2020 and 2021. Water samples (20 mL) were processed via solid phase extraction using weak cation exchange (WCX) cartridges (3 cc, 60 mg) and analyzed via liquid...

A collection of analysis-ready Multilevel Monitoring System (MLMS) datasets for wells in the U.S. Geological Survey (USGS) aquifer-monitoring network, Idaho National Laboratory (INL), Idaho. Administered by the USGS INL Project Office in cooperation with the U.S. Department of Energy.

These datasets provide weekly differences of early estimates of 2024 fractional cover for exotic annual grass (EAG) that were released from April to late June. The EAG estimates were publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contained five fractional cover maps along with their corresponding confidence maps for: 1) a...

In support of a groundwater-flow model of the Virginia Eastern Shore, altitudes were determined for the tops of hydrogeologic surfaces, including incised paleochannel surfaces, that compose the framework within the model area. Rasters were generated from the altitude data for the tops of the surficial aquifer, upper confining unit, upper aquifer, middle confining unit, middle aquifer...
