USGS National and Global Oil and Gas Assessment Project-Montana Thrust Belt Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project-Montana Thrust Belt Province: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units and input data for the assessment of undiscovered gas resources in the Montana Thrust Belt province in Montana. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level...
Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios Hawaiian Islands downscaled climate projections for baseline (1983-2012), mid- (2040-2059), and late-century (2060-2079) scenarios
Global downscaled projections are now some of the most widely used climate datasets in the world, however, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we apply steps to improve the utility of two such global datasets (CHELSA and WorldClim2) to provide credible climate scenarios for climate change impact studies in...
Cone penetrometer and elevation measurement data of coastal wetland plant states for resilience quantification, Louisiana, USA (2019) Cone penetrometer and elevation measurement data of coastal wetland plant states for resilience quantification, Louisiana, USA (2019)
These datasets provide: 1) field-collected geotechnical data, and 2) Real-Time-Kinematic GPS elevation data for coastal salt marsh in the Port Sulphur area, Louisiana from 2019.
Microanalysis of samples collected from the Sulfur Springs Draw calcrete-type uranium deposit in the Southern High Plains, Texas, USA Microanalysis of samples collected from the Sulfur Springs Draw calcrete-type uranium deposit in the Southern High Plains, Texas, USA
This data release presents the results of microanalysis of 2 samples SSD15_01A (1 thin section and 1 composite chip sample), and SSD15_01B (1 thin section). The samples were collected in 2015 by U.S. Geological Survey geologists Bradley Van Gosen and Susan Hall from surface exposures of uranium mineralization in Sulfur Springs Draw, in Martin County, Texas (Van Gosen and Hall, 2017). The...
Deep (15-second) seismic reflection profiles CC-1 and CC-2 extending from the eastern California Coast Ranges across the Great Valley into the Sierran foothills at about latitude 37.25 Degrees N Deep (15-second) seismic reflection profiles CC-1 and CC-2 extending from the eastern California Coast Ranges across the Great Valley into the Sierran foothills at about latitude 37.25 Degrees N
This data release contains deep seismic reflection profiles CC-1 and CC-2, which extend eastward from within the California Coast Ranges across the Great Valley and into the Sierran foothills, with a combined east-west length of about 140 km at about the latitude of the town of Merced (37.25° north latitude). The records are processed to 15 seconds two-way time and thus extend deep into...
Charcoal data from four sites in Great Dismal Swamp National Wildlife Refuge - August 2022 Charcoal data from four sites in Great Dismal Swamp National Wildlife Refuge - August 2022
Charcoal counts and radiocarbon dates from four sediment cores collected in Great Dismal Swamp in 2017 and 2018 were incorporated into a synthesis of charcoal records from northern hemisphere peatlands (Sims et al., in review). Macroscopic charcoal was counted in three size classes: 125-250 micrometers, and 250-500 micrometers, and >500 micrometers. Uncalibrated radiocarbon dates were...
Array-based Surface-wave Active- or Passive-source Recordings at 10 Seismic Station Sites in California Array-based Surface-wave Active- or Passive-source Recordings at 10 Seismic Station Sites in California
The dataset is consisted of travel-time records (SWM_DATA.zip) in SEG2 format recorded using multi-station MASW and AM arrays near 10 seismographic stations located in California. A table in the spreadsheet (SWM_deployment_record.xlsx) summarizes the data collection, with multiple sheets providing further details about array configurations at each station. Stations included in the...
Decompartmentalization Physical Model (South Florida Water Management District) Periphyton Abundance and Biovolume Data 2017–21 (ver 1.1, April 2024) Decompartmentalization Physical Model (South Florida Water Management District) Periphyton Abundance and Biovolume Data 2017–21 (ver 1.1, April 2024)
Periphyton is a complex community of detritus, bacteria, fungi, and algae that grows attached to submerged substrates. Assemblage structure data for algae and cyanobacteria from periphyton samples were collected on a monthly basis from 2017 to 2021. Compiled data were reported as absolute abundance (cells) and biovolume per volume as well as absolute abundance (cells) and biovolume per...
Vegetation and soil cover data for long-term monitoring plots within Browns Park National Wildlife Refuge, Colorado, USA Vegetation and soil cover data for long-term monitoring plots within Browns Park National Wildlife Refuge, Colorado, USA
Sixty-eight monitoring plots within the Browns Park National Wildlife refuge in Northwest Colorado were surveyed in the Summer of 2007 and 2021 for vegetation-community changes after grazing cessation in 1986. Surveys consisted of line-point intercept measurements at 0.5m intervals along three 15-m transects arranged in a spoke around plot center at each plot location.

A set of comma-separated value tables containing data for streamflow, water quality, surface-water features, and produced waters in the energy development area of the Williston Basin in eastern Montana, western North Dakota, and northwest South Dakota.
Soil, geologic, geomorphic, climate, and vegetation data from long-term monitoring plots (2009 - 2018) in Arches, Canyonlands, and Capitol Reef National Parks, Utah, USA Soil, geologic, geomorphic, climate, and vegetation data from long-term monitoring plots (2009 - 2018) in Arches, Canyonlands, and Capitol Reef National Parks, Utah, USA
These data (all data tables for the data release) represent a suite of biotic and abiotic variables that characterized plant communities and the geologic, geomorphic, edaphic, climatic, and land use history context in which distinct plant communities occur. In 2009, the National Park Service's Inventory and Monitoring program for the Northern Colorado Plateau Network (NCPN) began...
