Data

This data release from the U.S. Geological Survey (USGS) presents the results of radiometric analyses conducted on sediment samples collected in 2016 and 2019 from Pahranagat Wash, behind Arrow Canyon Dam in northern Clark County, Nevada. In 2016, core samples were collected from two well sites: USGS 364453114483401 (ACWEST) and USGS 364448114481001 (ACEAST). Additionally, a shallow...

Radiometric data were collected at the Grand Junction Regional Airport radiometric calibration facility in March 2023 and August 2024. The facility consists of five ~9 by ~12 m (30 x 40 feet) concrete pads, each 18 in thick. Each pad provides sources of radioelements that are spatially homogeneous (see Ward, 1978). Three pads are dedicated K, Th, and U pads, each of which contains high...

Radiometric data (gamma ray spectrometry) were collected via a small uncrewed airborne system (sUAS) in June 2024 to characterize four distinct mine waste features in Southwestern New Mexico. Walking surveys with a handheld meter were also conducted over parts of the survey areas to provide ground truth checks for the airborne data. Survey sites and their respective areas covered include...

The Illinois River receives nutrients from point and non-point runoff from upstream urban and agricultural areas. These excess nutrients could be contributing to harmful algal blooms in the Illinois River and its tributaries. The Upper Mississippi River Restoration Program has been monitoring water quality on the La Grange Pool in the Illinois River since 1993. The data collected from...

U.S. Fish and Wildlife Service (USFWS) has designated Pyrgus wyandot (W. H. Edwards) (Appalachian Grizzled Skipper, AGS) as a Species of Concern based on its declining populations and the paucity of information on its current status. Our objective was to conduct range-wide surveys to locate extant AGS colonies and to quantify the number of AGS observed at each location. From 2021 – 2024...

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2025. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub...

The East River is an agricultural tributary to the Lower Fox River and the Environmental Protection Agency (EPA) Green Bay Area of Concern (AOC) in northeast Wisconsin. This tributary has known excessive phosphorus (P) and suspended sediment loads that contribute to habitat related impairments and downstream algal blooms. As part of the Great Lakes Restoration Initiative (GLRI), the U.S

These spatial layers were created to provide estimates of relative risk of a mule deer (Odocoileus hemionus) contracting chronic wasting disease (CWD) based on environmental properties of habitat visited by the deer. We modeled relative risk of disease transmission using location data from GPS-collared mule deer in Wyoming that were CWD-tested annually, and used generalized linear models...

This data release provides the full analytical dataset for fourteen new argon‑argon (⁴⁰Ar/³⁹Ar) radiometric ages from olivine tholeiite basalt flows at the Idaho National Laboratory (INL) on the eastern Snake River Plain, Idaho. Samples were collected from basalt flows in eight subsurface coreholes (43–450 ft below land surface) and five surface sites. The release includes machine...

This dataset contains six csv files representing timeseries survivorship, before and after stress testing results, and metabolomics data from a reciprocal transplant experiment using two species of coral, Montipora capitata and Porites compressa. Data were collected from 2023 to 2025 on the Windward side of Oʻahu, Hawaii with coral being transplanted to and from two bays, Kailua Bay and...

This data release presents concentration results obtained using an enzyme-linked immunosorbent assay (ELISA) method for imidacloprid and other neonicotinoid insecticides from samples collected in 30 urban streams across Virginia between August 2024 and July 2025. ELISA analyses were conducted at the U.S. Geological Survey Strategic Laboratory Science Branch in Boulder, Colorado. The...

The Restoration, Coordination, and Verification (RECOVER) program is a collaboration among federal and state agencies, Tribes, and other institutions that conduct and guide scientific research for Everglades restoration in southern Florida. RECOVER members evaluate restoration plans and designs and assess real-world environmental conditions. One of the tools used by the RECOVER program...
