This dataset includes 2055 digital images of tree ring samples from avalanche paths in southeast Alaska, northwest Montana and western Colorado, USA. There is also a .csv file with metadata for each scan located at the bottom of the zipped folder list in the attached file section.
An Expert Elicitation to Inform Coastal Management Decision-Making for Mitigating Future Hazards: Elicited Values An Expert Elicitation to Inform Coastal Management Decision-Making for Mitigating Future Hazards: Elicited Values
A scientific expert elicitation was conducted by the U.S. Geological Survey in March 2022 to address the feasibility of restoring coastal environments in response to future hazards to best meet management objectives. Subject matter experts produced probabilistic estimates of coastal change metrics used to evaluate decision objectives and alternatives informed by a stakeholder advisory...
Substrate classifications of three rivers in eastern Oklahoma Substrate classifications of three rivers in eastern Oklahoma
Suitable spawning substrates, such as bedrock, boulder/cobble, and gravel, for Paddlefish (Polyodon spathula) that were were mapped in tributaries of Lake Eufaula (Deep Fork River and Brushy Creek) and Hugo Lake (Kiamichi River) via Humminbird Helix 10 sidescan sonar. These datasets show the mosaicked image files and locations of four different substrate types (bedrock, boulder/cobble...
Whole-rock geochemical data for volcanic rocks sampled in northwestern Utah and adjacent states Whole-rock geochemical data for volcanic rocks sampled in northwestern Utah and adjacent states
This release of whole-rock geochemical data for northwestern Utah and adjacent states is for volcanic rocks sampled and analyzed from 1977 to present. The rocks range from Eocene to Quaternary in age and represent lava flows, tuffs, and subvolcanic intrusions. The data release includes new, previously unpublished data as well as results for USGS-processed samples that are publicly...
Biological soil crust and vegetation cover from two previously grazed grasslands within Canyonlands National Park, Utah Biological soil crust and vegetation cover from two previously grazed grasslands within Canyonlands National Park, Utah
These tabular data were compiled to monitor vegetation and biocrust cover two previously grazed grassland located in the Needles District of Canyonlands National Park. Objectives of this study are to document potential changes in biological soil crust (biocrust) and vegetation cover and species composition over time and with ongoing U.S. National Park Service (NPS) management. These data...
Dataset describing riparian vegetation trends of selected areas in Baja California Sur, Mexico from 2016-2024 Dataset describing riparian vegetation trends of selected areas in Baja California Sur, Mexico from 2016-2024
This dataset includes raster images of trends in normalized difference vegetation index (NDVI) derived from Sentinel-2 imagery for riparian vegetation within the Los Planes watershed of Baja California Sur, Mexico. A model was first trained to identify riparian vegetation using cloud-masked Sentinel-2 imagery from 2016-2024 and stream delineations derived from a 10m Japanese Aerospace...
Aquatic reflectance data from Sentinel-2 satellite imagery paired with discrete chlorophyll-a measurements in Oregon, Ohio, and Florida in the United States from January 2016 through September 2023 Aquatic reflectance data from Sentinel-2 satellite imagery paired with discrete chlorophyll-a measurements in Oregon, Ohio, and Florida in the United States from January 2016 through September 2023
Aquatic reflectance data from Sentinel-2 satellite imagery is paired with discrete chlorophyll measurements across Oregon, Ohio, and Florida in the United States. The dataset contains a csv data file (CyAN_S2_Matched_WQ_S2.csv), a csv data dictionary file (CyAN_S2_Matched_WQ_S2_data_dictionary.csv) that describes each of the columns in the data file, and a zip file of python scripts...
SHRIMP U-Pb geochronologic data for Elkhorn Mountains Volcanics and Boulder batholith satellite plutons, western Montana, U.S.A. SHRIMP U-Pb geochronologic data for Elkhorn Mountains Volcanics and Boulder batholith satellite plutons, western Montana, U.S.A.
These data are for a geochronologic study of Cretaceous Elkhorn Mountains Volcanics and several discrete satellite plutons adjacent to the Cretaceous Boulder batholith of western Montana. Zircon from the two volcanic units of the Elkhorn Mountains Volcanics and four samples of satellite plutons of the Boulder batholith were dated by sensitive high resolution ion microprobe (SHRIMP). When...
Calibration data from Mount Hamilton, California, for USGS Volcano Science Center gravimeters Calibration data from Mount Hamilton, California, for USGS Volcano Science Center gravimeters
Temporal changes in gravity, also called microgravity in volcano geodesy and exploration geophysics applications, provide a means of measuring mass change beneath the surface—for example, due to the accumulation or withdrawal of water, magma, or other fluids. Relative spring-based gravimeters, however, require calibration to establish consistency between instruments, and to assess...
Water Quality of Terminal Lakes Across the Great Basin of the Western United States, 2023 – 2026 Water Quality of Terminal Lakes Across the Great Basin of the Western United States, 2023 – 2026
The Great Basin of the Western United States hosts dozens of terminal lake systems that provide critical, abundant, and diverse ecosystems that support migratory bird species, local wildlife, and nearby communities. Water quality varies across terminal lakes in the region depending on basin geology, anthropogenic water use, climate, hydrology, and water quantity. Seasonal and long-term...
Modeled riparian plant community habitat suitability along the Colorado River in Grand Canyon in support of resource impact analysis for Post-2026 reservoir operational alternatives Modeled riparian plant community habitat suitability along the Colorado River in Grand Canyon 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 used to illustrate how six operational strategies (one baseline and 5 alternatives) for Glen Canyon Dam could affect riparian plant communities along the Colorado River between Glen Canyon Dam and Lake...
