Topographic and bathymetric data, structure from motion imagery, and ground control data collected at Head of the Meadow, Truro in February 2021, U.S Geological Survey Field Activity 2021-014-FA Topographic and bathymetric data, structure from motion imagery, and ground control data collected at Head of the Meadow, Truro in February 2021, U.S Geological Survey Field Activity 2021-014-FA
These data map the beach and nearshore environment at Head of the Meadow Beach in Truro, MA, providing updated regional context for the 2019 CoastCam installation. CoastCam CACO-01 are two video cameras aimed at the beach that view the coast shared by beachgoers, shorebirds, seals, and sharks. These data were collected as part of field activity 2021-014-FA and a collaboration with the...
Southwestern Riparian Plant Trait Matrix, Colorado River, Grand Canyon, Arizona (ver. 2.0, 2022) Southwestern Riparian Plant Trait Matrix, Colorado River, Grand Canyon, Arizona (ver. 2.0, 2022)
Trait-based approaches to vegetation analyses are becoming more prevalent in studies of riparian vegetation dynamics, including responses to flow regulation, groundwater pumping, and climate change. These analyses require species trait data compiled from the literature and floras or original field measurements. Gathering such data makes trait-based research time intensive at best and...
Stable Isotopic Data (Delta13C and Delta2H) for Reference Materials HCG-1, HCG-2, and HCG-3 Stable Isotopic Data (Delta13C and Delta2H) for Reference Materials HCG-1, HCG-2, and HCG-3
Stable carbon and hydrogen isotopic data generated by off-line preparation and dual inlet mass spectrometric analysis used the determine the recommended values for the reference materials HCG-1, HCG-2, and HCG-3.
Graphite deposits in the United States Graphite deposits in the United States
This U.S. Geological Survey (USGS) data release provides the descriptions of 10 U.S. sites that include mineral regions, mineral occurrences, and mine features that contain enrichments of graphite. To be included in this data release, sites must have a contained resource and (or) past production of more than 1,000 metric tons of graphite, which is approximately 3 percent of the average...
MMODFLOW-OWHM used to characterize the flow system of the Petaluma River Watershed, Sonoma County, California MMODFLOW-OWHM used to characterize the flow system of the Petaluma River Watershed, Sonoma County, California
The Petaluma Valley integrated hydrologic model (PVIHM) was developed by the U.S. Geological Survey (USGS) in cooperation with the Sonoma County Water Agency and the City of Petaluma. The PVIHM simulates the 99,000-acre Petaluma valley watershed and includes 54,000 acres where groundwater flow is active. The model simulates 56 years of historical hydrology (water years 1960–2015) that...
Exogenous and endogenous factors influence invasive reptile movement at multiple scales, 2018 - 2019 Exogenous and endogenous factors influence invasive reptile movement at multiple scales, 2018 - 2019
These data reflect movement values for brown treesnakes from Guam that were translocated (moved by humans) to new locations or were resident (left in place) on Guam. The data are related to the specimen's treatment group, individual values, locations and other details affiliated with radio telemetry based acquisition and positional changes by the individual snakes across tracking events...
