Thermistor strings with sensors spaced at 25-centimeter intervals were installed in three boreholes extending from the ground surface to depths of up to 4.25 meters at Barter Island, Alaska. The sites were located near the bluff edge overlooking the open Beaufort Sea coast. Temperature measurements were programmed to be collected hourly from late spring through early fall in 2016 (May 31...

A ground-based magnetic survey was conducted in the southwest corner of Yakima Training Center, Washington, in 2025. Magnetic surveys are passive, non-contact, surface geophysical methods that measure the total ambient magnetic field. The magnetic survey utilized a Geometrics G-864 cesium magnetometer. Survey lines were carried out to better understand the subsurface along a prominent...

During December 2023, the U.S. Geological Survey collected ground-penetrating radar (GPR) data in select small peat bogs near the Quashnet River to map the depth to bedrock for use as inputs to a groundwater flow model. This data release contains the raw GPR data from 22 GPR profiles covering more than 1.8 kilometers.

In September 2025, the U.S. Geological Survey, in cooperation with Idaho Power Company, conducted a pilot geophysical survey along the Snake River between the Boise River confluence and Swan Falls Dam in southwestern Idaho. The purpose of the survey was to evaluate the utility of ground-penetrating radar (GPR) for mapping the spatial distribution and thickness of gravel deposits within...

This data release documents estimates of groundwater recharge for the U.S. portion of the Salish Sea Basin in northwestern Washington. A U.S. Geological Survey Soil-Water-Balance (SWB) model (Westenbroek and others,2018) was developed for Hydrologic Unit Code 17110 to simulate the spatial distribution of net infiltration below the root zone on a daily time step from January 1, 1980...

Aspen stands (Populus tremuloides Michx.) are declining in western U.S. forests due to drought, changing climate, and altered disturbance regimes. Management of aspen has focused on promoting vegetative suckering, which requires viable rootstock. With increasing wildfire frequency and severity in the West, there are opportunities for aspen reforestation post-fire. We tested how deadwood...

Cisco and Bloater growth data from hatchery reared fish were collected in association with a project to repopulate Lake Ontario native prey species. Fish were grown and measured under hatchery conditions for up to nine months before being released into Lake Ontario. Weekly measurements of total length, total weight, and morphometrics were recorded for both species to determine growth...

This data release and metadata contains radio telemetry signal data used to track and describe movement and activity of Brown Treesnakes (Boiga irregularis) and Micronesian Starlings (Aplonis opaca) on Andersen Air Force Base, Guam, 2021-2022. Using a node network radio telemetry tracking system, multiple nodes would make detections of animals and record signal strength that could be...

The datasets were collected as part of a project to model fire refugia and severity from remotely sensed vegetation, topographic, fire weather, and fire growth variables. These data were used to evaluate changes in patterns of fire refugia and severity in relation to drivers. They represent a key deliverable of this research, designed to inform conservation and management across the...

In association with a project to estimate stream habitat use by two fish species; habitat parameters where slimy sculpin and rainbow trout were captured were recorded. Habitat use was observed using a backpack electrofisher in order to determine where fish were residing. Total stream habitat was calculated using equally spaced transects with observational recording of stream water depth...

In the moist, coniferous forests of Oregon and Washington, a dense network of headwater streams supports high levels of amphibian species endemism and diversity, including the torrent salamanders (Rhyacotriton spp.). The Columbia and Cascade torrent salamanders (R. kezeri and R. cascadae, respectively) are species of greatest conservation need, but current information is insufficient for...

This data release contains individual freshwater mussel data used in an augmentation effort within the Clinton River watershed located near Detroit, Michigan in September 2024. Mussels were individually tagged with a unique identification tag, and a subset of mussels received a passive integrated transponder tag to be able to detect their location in June 2024. All mussels were measured...
