Data

This data release is tree-ring data near Columbine Lake and surrounding region, Grand County, Colorado (Latitude 40.27˚ N, Longitude -105.83˚ E NAD83). Re-collection of four existing tree-ring sites (Hot Sulphur Springs Psuedotsuga menziessii (HSU), Lexan Creek Picea engelmannii (LCU), Monarch Lake Pinus ponderosa (MLU), and Vasquez Mountain Psuedotsuga menziessii (VMU)) was conducted to update da

The primary habitats for insular mole skinks in Florida are sand beaches, beach berms, and dunes, making them particularly vulnerable to sea level rise (SLR) and storm surge. We used the most recent SLR projections, high resolution lidar-based digital elevation models, a combination of a comprehensive land cover and hand-digitized aerial imagery, and the latest storm surge simulations to predict t

This dataset includes surveys for the Eastern red-spotted newt (Notophrhalamus viridescens viridescen). The survey data includes 264 survey sites, landscape level covariates including human interference index, and landcover type, and survey level covariates including survey date and detection method.

Dissolved noble gas data were collected using a portable mass spectrometer mounted on inflatable rafts on the Colorado River near Glenwood Springs, Colorado and the Virgin River near La Verkin, Utah. Data were collected approximately every 3 to 10 minutes for a suite of noble gases including helium (He), neon (Ne), argon (Ar), krypton (Kr), and xenon (Xe). Patterns in observed dissolved He concent

Habitat restoration efforts to conserve wildlife species are often conducted along a range of local site conditions, with limited information available to gauge relative outcomes for habitat suitability among sites and identify those that may lead to the greatest returns on restoration investment. We leveraged existing resource selection function models to generate heatmaps of spatially varying ha

This data release consists of a two-dimensional (laterally averaged) hydrodynamic water-quality model (CE-QUAL-W2; Wells, 2019) of Green Peter and Foster Lakes for the 2023 calendar year, and three theoretical deep drawdown operational scenarios that apply the 2023 model to calendar year 2024. The model and scenarios were used to gain insights into the thermal processes in Green Peter and Foster L

Two spectroradiometers, a Malvern Panalytical Analytical Spectral Devices FieldSpec® 4 Hi-Res (hereafter referred to as ASD spectrometer) and a high sensitivity spectrometer, OCEAN-HDX-VIS-NIR®, from Ocean Optics (hereafter referred to as HDX) were used to collect reflectance measurements of materials in a controlled indoor setting at the USGS Spectroscopy Lab in Denver, Colorado on July 8, 2022 t

This U.S. Geological Survey (USGS) data release represents data for the creation of a spatially explicit Bayesian network model that predicts Brown Pelican nests on islands across the U.S. portion of the Gulf of Mexico. Well-targeted management plans are needed to achieve Brown Pelican population objectives (number of breeding pairs) because conservation and restoration opportunities are limited a

This metadata record describes a series of tabular datasets containing metrics used to characterize periods of anomalously low storage for select large reservoirs across the Conterminous United States for the climate years (April 1 – March 31) from 1981 to 2020. These data support the associated Simeone and others (2024) publication. The reservoirs in this dataset are those included in the ResOpsU

In 2024, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BOT), carried out comprehensive hydrographic and water-quality surveys, and activity and disturbance assessments of 44 total water bodies encompassing lakes and rivers within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality conditions, and on-site field

This study examined effects of the brominated flame retardant hexabromocyclododecane (HBCD) on the avian endocrine system. Japanese quail (Coturnix japonica) were exposed to multiple doses of HBCD over multiple generations through feed and by maternal deposition into the egg. Liver transcriptomes were examined to identify genes and pathways directly affected by HBCD to better understand the mechan
