Topographic and bathymetric data, structure from motion imagery, and ground control data collected at Head of the Meadow Beach, Truro, Massachusetts in March and April 2023, U.S. Geological Survey Field Activity 2023-011-FA Topographic and bathymetric data, structure from motion imagery, and ground control data collected at Head of the Meadow Beach, Truro, Massachusetts in March and April 2023, U.S. Geological Survey Field Activity 2023-011-FA
The data in this release re-map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA and provide updated environmental context for the 2020 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. This is related to the field activity 2022-015-FA and a collaboration with the National Park Service at Cape Cod National...
Groundwater elevation data and models in and around select California oil fields (ver. 4.0, March 2026) Groundwater elevation data and models in and around select California oil fields (ver. 4.0, March 2026)
This data release contains groundwater elevation data and the associated model/code used to create groundwater elevation surfaces in and around select oil fields in California. The data and model provided here are intended to supplement interpretative manuscripts. Specific study areas will be added as Child Items found in this data release. Groundwater elevations are usually collected...
PHREEQC files for geochemical simulations in Horn Creek, Grand Canyon, AZ PHREEQC files for geochemical simulations in Horn Creek, Grand Canyon, AZ
PHREEQC files included in this ScienceBase product include the input (.pqi) and output (.pqo) files formatted for use in PHREEQC and as basic text files, and the information regarding samples used in the simulations. The files were used to interpret changes in water quality between 2018 and 2022 within the Horn Creek watershed of Grand Canyon for the associated publication (add citation...
Study attributes and summary results of fish responses to restoration extracted from systematic review of studies published between 2010 and 2020 Study attributes and summary results of fish responses to restoration extracted from systematic review of studies published between 2010 and 2020
Study attributes and summary results of fish responses to restoration extracted from systematic review of studies published between 2010 and 2020. Data were used in meta-analysis as part of the publication "Are river restoration projects designed and evaluated to effectively address current stressors to inland fish and fisheries?" by Rogosch et al. Each row is data extracted from a study...
Larval headwater stream amphibian captures from the Trask River Watershed Experimental Study of forest harvest impacts, 2008-2016 Larval headwater stream amphibian captures from the Trask River Watershed Experimental Study of forest harvest impacts, 2008-2016
Forest harvest is one of the primary landscape-scale management actions affecting riparian forests of the Pacific Northwest, U.S, yet the effect of harvest on headwater steam amphibians is largely understudied. Existing information is often limited because of the difficulty separating movement and emigration processes from occupancy and abundance estimates. We designed a before-after...
Geochemistry of fine sediment from San Francisco Bay shoals (2012) and tributaries (2010, 2012, 2013) Geochemistry of fine sediment from San Francisco Bay shoals (2012) and tributaries (2010, 2012, 2013)
Elemental chemistry and weight percent of the less than 0.063 mm fine sediment fraction are reported for surface sediments from shoals, the ebb tide delta, local tributaries, and inland rivers that carry sediment to San Francisco Bay, California.
