Data

We captured Mohave ground squirrels from four study sites in the Coso Range, California, between 1988 and 2021. This dataset includes capture and recapture records of squirrels at each site and individual and environmental variables associated with those records. We used these data in a mark-recapture analysis to estimate six demographic parameters of Mohave ground squirrels: survival...

This is accompanying data produced for the study "Implications of Model Selection: Inter-Comparison of Publicly-Available, CONUS-Extent Hydrologic Component Estimates". These datasets were converted from their primary structures (rasters and shapefiles) to EPA Ecoregions Level I. Conversion was performed by averaging timestep layers via mean area weight to produce a single vector of...

This dataset includes model projections of seasonal temperature (T), precipitation (P), and runoff (R) from 214 climate simulations from coupled model intercomparison project (CMIP) 3 and CMIP5 scenarios for 19-year periods centered on 2030, 2060, and 2090. The summaries of the climate model projections are presented as percentiles (5th, 25th, 50th, 75th, and 95th) of seasonal (October...

Agricultural activities can impact water quality and the health of aquatic ecosystems. A conceptual framework was developed that combined generalized concepts on the movement of water, the environmental behavior of chemicals and eroded soil, and the designed functions of various agricultural activities. The framework addresses the impacts on water quality of a broad range of agricultural...

This model archive provides all data, code, and model outputs used in the corresponding manuscript (Barclay and others, 2026) to test machine learning (ML) methods for downscaling and multi-scale modeling of stream temperature to combine an ML model and/or input data at coarse spatial resolution with an ML model and/or input data at fine spatial resolution to predict stream temperatures...

Groundwater recharge potential was mapped using airborne electromagnetic (AEM) survey data collected over the glaciated part of eastern Nebraska. Groundwater recharge potential was mapped by calculating the Vertically integrated connectivity (VIC) for each AEM sounding along 18,000 line-miles of survey data. VIC values were interpolated to produce two versions of groundwater recharge...

Data set consists of scanned seismic drum records recorded at Mount Pinatubo between April 30 and June 17, 1991. The archive contains 145 drum records that recorded seismicity associated with the 1991 eruptions. These drum records are the only continuous seismic records produced from a local network of seismic stations. The images of the drum records are in JPG format.

Broad-area, high-resolution, boat-based water quality mapping surveys of the San Francisco Bay, the Sacramento-San Joaquin Delta (Delta), Lake Oroville, and San Luis Reservoir were conducted at various times between April 2015 and April 2022. Each survey was conducted over the course of a single day. The region covered included the east-west axis of the San Francisco Bay Delta from the...

This metadata record contains 5 tables of sediment concentration data used to assess correlations of land use with detections and concentrations of polychlorinated biphenyls, per-and- poly-fluoroalkyl substances, elemental metal composition, percent organic carbon and fines. Microbial communities were measured in each sample to identify the presence of dechlorinating microorganisms in...

This data release contains 40Ar/39Ar isotopic data for manganese oxides collected in the southern and central Appalachian Mountains of Tennessee, Virginia, and West Virginia. Furnace- and laser-heated analyses of cryptomelane separates from 84 samples are included, along with sample site location data.

In support of the U.S. Army Corps of Engineers Long Term Resource Monitoring Mississippi River program, water quality data were collected in 2024 and 2025 in the Upper Mississippi River Basin. Data were collected in 2024 to document spatial heterogeneity in water quality across seasons and hydrologic conditions with a focus on understanding patterns in chlorophyll. Additional data were...

Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) led six sampling events between November 2022 and March 2024 in support of a collaborative research project investigating coastal boundary fluxes of dissolved analyte loads to the West Florida Shelf (National Science Foundation Grant Award OCE-2148989, Project 880516). During each...
