Black bear (Ursus Americanus) spatial capture recapture dataset in and near Glacier National Park, Montana, USA, 2004

Tabular and raster data containing spatial capture recapture records for male and female black bears (Ursus americanus) in Glacier National Park and surrounding landscape collected from June - October 2004 and associated tabular data files required for analysis of data with spatial capture connectivity models and raster data describing the ouput from SCR models. Associated tables and rasters inclu

Input and results from a random forest classification (RFC) model that predicts redox conditions in groundwater in the contiguous United States

This data release provides model inputs and outputs for a model that predicts redox conditions in groundwater in the contiguous United States. Input variables describe the hydrology, soils, geology, and hydrologic position of groundwater sample locations. The data release accompanies a journal article that describes model development and applications (Tesoriero_and_others_2023).

Groundwater-quality data in the Gilroy Hollister basin and surrounding areas Domestic-Supply Aquifer Study Unit, 2022: Results from the California GAMA Priority Basin Project

The U.S. Geological Survey collected groundwater samples from 33 wells used for domestic and small system drinking water supplies in Santa Clara and San Benito Counties, California in 2022. The wells were sampled for the Gilroy Hollister basin and surrounding areas Domestic-Supply Aquifer Study Unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Pro

USGS National and Global Oil and Gas Assessment Project—Raton Basin-Sierra Grande Uplift Province, Raton Continuous Resources: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in upper Cretaceous marine shales in the Raton Basin-Sierra Grande Uplift Province, Colorado and New Mexico. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment

Dead Tree Detection Validation Data from Sequoia and Kings Canyon National Parks

Most of these data were collected in order to create a database of tree locations for use in calibrating remote sensing tools and products, particularly dead tree detection tools and canopy species maps. Data include tree locations, species identification, and status (live, dead, and, if dead, sometimes includes information on foliage and twig retention). They are a collection of different samplin

Carbon, Nitrogen, and Sulfur Stable Isotopes from Primary Producers, Invertebrates, and Fish at the Nisqually River Delta, Washington from 2011, 2012, and 2015

This dataset consists of carbon, nitrogen, and sulfur stable isotope data from primary producers, invertebrates, and fish from the Nisqually River Delta, Washington from 2011, 2012, and 2015. Data were collected to determine food web structure in different habitat zones within the entire river delta. Data collection for primary producers and invertebrates were led by U.S. Geological Survey, while

Bayou Bonfouca Marsh Creation (PO-104): 2016 and 2018 land-water classifications

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting

Grain-size analysis data of sediment samples from the beach and nearshore environments at the Pea Island National Wildlife Refuge DUNEX site, North Carolina in 2021

This data release supersedes version 1.0, published in September 2022 at https://doi.org/10.5066/P9XEFRYR. Versioning details are documented in the accompanying revision_history.txt file. These data provide grain-size measurements from sediment samples collected as part of the USGS DUring Nearshore Event eXperiment (DUNEX) site on Pea Island National Wildlife Refuge, NC. DUNEX is a multi-agency,

Alaska Geochemical Database Version 4.0 (AGDB4) including best value data compilations for rock, sediment, soil, mineral, and concentrate sample media

The Alaska Geochemical Database Version 4.0 (AGDB4) contains geochemical data compilations in which each geologic material sample has one best value determination for each analyzed species, greatly improving efficiency of use. The relational database includes historical geochemical data archived in the USGS National Geochemical Database (NGDB), the Atomic Energy Commission National Uranium Resourc

Digital elevation model of Mount St. Helens, Washington and vicinity prior to the 1980 eruption

On May 18, 1980, Mount St. Helens, Washington, exploded in a spectacular and devastating eruption that resulted in previously unimaginable events that drastically altered the mountain and the surrounding area. One unprecedented event was the collapse of the summit and north flank of the volcano forming a huge landslide known as the ‘debris avalanche’ with a total volume of about 2.5 km3 (3.3 billi

Estimated Post-Emergence Period for Denning Polar Bears of the Chukchi and Beaufort Seas

These data are estimates of den emergence date, den site departure dates, and duration at den sites as well as post-emergence observations for female polar bears sampled in the southern Beaufort Sea subpopulation 1985-2016 and the Chukchi Sea subpopulation 2008-2017. The data were used to better understand the importance of time spent at the den site post-emergence. Emergence dates and departure d

Northwestern Pond Turtle Survey Data in Northern California Forest Streams, 2021-2022

These data are from joint visual encounter and environmental DNA (eDNA) surveys conducted for northwestern pond turtles (Actinemys marmorata) in streams on privately-owned timberlands in northern California.
