Data

Using a bioenergetic model, demographic data for the Rainbow Trout (Oncorhynchus mykiss) population were compiled and used to estimate total prey consumption in the Colorado River, Glen Canyon , AZ. Additionally, other data including invertebrate diet, drift, and benthic measurements were used to make generalized estimates of daily production rates for the most common benthic...

Plant roots have the best-understood mutualisms with microbes, but leaf and bract cell endosymbiosis have not been previously reported. Leaf and bract cells of more than 30 species in 18 families of seed plants were surveyed for the presence of intracellular bacteria and several experiments were designed to find and analyze nutrient exchanges between bacteria and plant cells. This...

These data describe the area of different habitat covered in water as determined via three approaches: manual surveys, digitized aerial imagery, and categorization of the newly available dynamic surface water extent dataset derived from satellite imagery. These data support a scientific publication.

These datasets describe channel adjustments over a 60-year period to dams in the Missouri National Recreational River (MNRR), South Dakota and Nebraska. Datasets include a channel geometry analysis from cross-sections, banklines digitized and interpreted to predict future bank erosion sites from aerial photography, and models of floodplain inundation over a range of discharges. There are...

Within the U.S. Geological Survey (USGS), three-dimensional (3D) geologic models are created as part of geologic framework studies, to support energy, minerals, or water resource assessments, and to inform geologic hazard assessments. Such models are often used within the organization as digital input into process and predictive models. 3D geological modeling typically supports research...

This data release is the update of the U.S. Geological Survey - ScienceBase data release by Bera (2021), with the processed data through September 30, 2021. The primary data for water year 2021 (a water year is the 12-month period, October 1 through September 30, in which it ends) is downloaded from the Argonne National Laboratory (ANL) (Argonne National Laboratory, 2022) and is...

This dataset is derived from images from a variety of Earth observing satellite imagery sources collected at known walrus coastal haulouts in Alaska and Chukotka, Russia. Earth observing imagery sources used in this data release include (but are not limited to) optical imagery collections by: (1) the European Space Agency's Sentinel-2 mission, (2) the Plant Labs Planet Scope...

We have archived the derived data files and R/JAGS code for our analysis as a U.S. Geological Survey data release (link ). The code is divided into three R scripts: 1) pbdens_landdens_JWM.r contains R code for fitting hierarchical Bayesian models of polar bear maternal den abundance and distribution for the Southern Beaufort Sea (SBS) subpopulation, 1982-2015. This script requires the...

This digital data release contains previously published geologic data compiled for the North Platte 250k quadrangle, a region in west-central Nebraska largely covered by Quaternary deposits, with exposures of Tertiary Ogallala and Brule formations in the southern portion of the study area. Geologic map data were compiled for the purposes of digitizing the geologic data as part of the...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered gas resources in the Montana Thrust Belt province in Montana. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level...

Global downscaled projections are now some of the most widely used climate datasets in the world, however, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we apply steps to improve the utility of two such global datasets (CHELSA and WorldClim2) to provide credible climate scenarios for climate change impact studies in...

These datasets provide: 1) field-collected geotechnical data, and 2) Real-Time-Kinematic GPS elevation data for coastal salt marsh in the Port Sulphur area, Louisiana from 2019.
