Digital database for the Geologic map of the Mohave Mountains area, Mohave County, western Arizona Digital database for the Geologic map of the Mohave Mountains area, Mohave County, western Arizona
This geologic database is a digitized version of the original 1:48,000-scale analog geologic map titled "Geologic map of the Mohave Mountains area, Mohave County, western Arizona", published by the U.S. Geological Survey (USGS) in 1999. The Mohave Mountains area surrounds Lake Havasu City, Arizona, in the Basin and Range physiographic province. The Mohave Mountains and the Aubrey Hills...
Modeled smallmouth bass entrainment and population growth rates in the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled smallmouth bass entrainment and population growth rates in the Colorado River in Glen and Grand Canyons in support of resource impact analysis for Post-2026 reservoir operational alternatives
These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). These data were outputs from models that estimate annual smallmouth bass entrainment through Glen Canyon Dam and annual smallmouth bass population growth rate (lambda) in the Colorado River below Glen Canyon Dam. The...
Argon geochronologic data from New Zealand's Ruapehu and Tongariro Volcanoes used to illustrate geochronology systematics Argon geochronologic data from New Zealand's Ruapehu and Tongariro Volcanoes used to illustrate geochronology systematics
Understanding the eruptive histories and petrogenetic models that underpin hazard assessments at active volcanoes typically requires high-precision ages for late Pleistocene to Holocene lava flows. These data vary in quality, typically related to textural and chemical variations in lava flow samples. These samples were part of an existing 40Ar/39Ar dataset for andesitic-dacitic rocks...
qPCR data from eDNA autosampler surveys for salmon migrating through the Lake Washington Ship Canal, June - September 2022 qPCR data from eDNA autosampler surveys for salmon migrating through the Lake Washington Ship Canal, June - September 2022
The content contains metadata from an eDNA survey that assessed the efficacy of an autonomous eDNA sampler for tracking Chinook, sockeye, and coho salmon migrating through the Lake Washington Ship Canal between June and September 2022.
Sediment temperature data, sediment redox data, and vertical specific discharge calculations from a salt marsh along the Herring River in Wellfleet, MA, September to December 2023 and June to July 2025 Sediment temperature data, sediment redox data, and vertical specific discharge calculations from a salt marsh along the Herring River in Wellfleet, MA, September to December 2023 and June to July 2025
Groundwater – surface water (GW-SW) exchange plays a fundamental role in the transport of energy and solutes in coastal salt marshes, which may be influenced by flow of terrestrial groundwater and tidal fluctuations. Sediment heat tracing and redox tracking experiments were conducted at a hillslope-adjacent fringing salt marsh on the Herring River in Wellfleet, MA to test new monitoring...
Ecosystem carbon stocks and fluxes on 62 Department of Defense installations within the contiguous United States from 2001-2021 Ecosystem carbon stocks and fluxes on 62 Department of Defense installations within the contiguous United States from 2001-2021
This data set contains tabular simulation model output from the Land Use and Carbon Simulator (LUCAS) summarizing annual changes in land use and land cover (LULC), ecosystem carbon stocks and ecosystem carbon fluxes within 62 U.S. Department of Defense (DOD) installations covering a total land area of approximately 106 hectares across the contiguous United States (CONUS) from 2001 to...
