Principal facts of regional gravity data in the central Upper Peninsula, Michigan, 2022-2023 Principal facts of regional gravity data in the central Upper Peninsula, Michigan, 2022-2023
Gravity data were collected in 2022 and 2023 to assist in mapping surface and subsurface geology in the central Upper Peninsula of Michigan. This data release provides principal facts for 666 new gravity stations that were acquired to supplement existing public gravity data coverage.
PRMS model inputs and outputs for the Upper Pipestem Creek basin (2017) PRMS model inputs and outputs for the Upper Pipestem Creek basin (2017)
This data release contains input for and outputs from hydrologic simulations of the upper Pipestem creek basin located in the Prairie Pothole region of North Dakota using the Precipitation Runoff Modeling System (PRMS).These simulations were developed to provide example applications of model calibration using alternative calibration targets. These PRMS model input and output data are...
Produced water chemistry data collected from the Oxnard Oil Field, Ventura County, and the Placerita Oil Field, Los Angeles County, 2018, California Produced water chemistry data collected from the Oxnard Oil Field, Ventura County, and the Placerita Oil Field, Los Angeles County, 2018, California
The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water and gas samples in the Oxnard Oil Field in Ventura County in August 2018 and the Placerita Oil Field in Los Angeles County in December 2018. Sampled sites included oil wells; injectate from tanks, pipelines, and injection wells where produced water from many...
Produced water chemistry data collected from the Poso Creek, Midway-Sunset, and Buena Vista Oil Fields, 2020-21, Kern County, California Produced water chemistry data collected from the Poso Creek, Midway-Sunset, and Buena Vista Oil Fields, 2020-21, Kern County, California
The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water and gas samples in the Midway-Sunset, Poso Creek, and Buena Vista Oil Fields in Kern County in 2020 and 2021. Sampled sites included oil wells; injectate from tanks, pipelines, and injection wells where produced water from many wells, after removal of oil, is...
Produced water major ion geochemistry, water isotopes, radium content, and field parameters and gas compositions from Niobrara Formation petroleum wells in the Denver-Julesburg Basin Produced water major ion geochemistry, water isotopes, radium content, and field parameters and gas compositions from Niobrara Formation petroleum wells in the Denver-Julesburg Basin
This data release includes field parameters (pH and specific conductance), major ion geochemistry (B, Ba, Br, Cl, Ca, Fe, K, Li, Mg, Mn, Na, Si, SO4, Sr), total dissolved solids, specific gravity, water isotopes (delta-2H and delta-18O), and radium isotopes (226Ra and 228Ra) from produced water samples taken from petroleum wells producing from the Niobrara Formation in the Denver...
Projected coastal flooding extents and depths for 1-, 20-, and 100-year return interval storms and 0.00, +0.25, +0.50, +1.00, +1.50, +2.00, and +3.00 meter sea-level rise scenarios in the Hawaiian, Mariana, and American Samoan Islands (ver. 2.0, September Projected coastal flooding extents and depths for 1-, 20-, and 100-year return interval storms and 0.00, +0.25, +0.50, +1.00, +1.50, +2.00, and +3.00 meter sea-level rise scenarios in the Hawaiian, Mariana, and American Samoan Islands (ver. 2.0, September
This data release provides flooding extent polygons and flood depth rasters (geotiffs) based on sea-level rise and wave-driven total water levels for the coast of the most populated Hawaiian, Mariana, and American Samoan Islands. Oceanographic, coastal engineering, ecologic, and geospatial data and tools were combined to evaluate the increased risks of storm-induced coastal flooding due...
Projected future groundwater balance for California Central Coast under different scenarios of land-use and climate change Projected future groundwater balance for California Central Coast under different scenarios of land-use and climate change
Tabular data output from a series of groundwater modeling simulations for five counties along the Central Coast of California, USA. We used a spatially explicit state-and-transition simulation model with stocks and flows that integrates climate, land-use change, human water use, and groundwater gain-loss to examine the impact of future climate and land use change on groundwater balance...
Projected mangrove distribution and ecosystem properties in the southeastern United States under climate change Projected mangrove distribution and ecosystem properties in the southeastern United States under climate change
We evaluated changes in mangrove distribution and ecosystem properties in the southeastern United States under climate change using known climate-ecological relationships, recent climate data for the period 1981-2010, and future projected climate data for the period 2071-2100 under two Shared Socio-economic Pathways (SSPs): the SSP2-4.5 and SSP5-8.5 scenarios, which correspond to...
Projections of post-fire cover of non-native short-lived grasses and forbs under current and future climate conditions Projections of post-fire cover of non-native short-lived grasses and forbs under current and future climate conditions
These data provide current and future projected post-fire invasion risk by non-native short-lived grasses and forbs based on vegetation cover data from 26,729 plots in the western United States that burned prior to being sampled. Projected post-fire invasion risk was calculated using random forests with gridded climate, soil, and topographic predictor variables following Prevéy et al....
Projections of Rangeland Fractional Component Cover Across Western Northern American Rangelands for Representative Concentration Pathways (RCP) 4.5 and 8.5 Scenarios for the 2020s, 2050s, and 2080s Time-Periods Projections of Rangeland Fractional Component Cover Across Western Northern American Rangelands for Representative Concentration Pathways (RCP) 4.5 and 8.5 Scenarios for the 2020s, 2050s, and 2080s Time-Periods
Climate change over the past century has altered vegetation community composition and species distributions across rangelands in the western United States. The scale and magnitude of climatic influences are largely unknown. We used fractional component cover data for rangeland functional groups and weather data from the 1985 to 2023 reference period in conjunction with soils and...
Prospective regions for marine minerals on the Alaska Outer Continental Shelf Prospective regions for marine minerals on the Alaska Outer Continental Shelf
This shapefile is of prospective regional outlines of where marine minerals may occur on the Alaska Outer Continental Shelf (OCS). Polygons were hand digitized based on a U.S. Geological Survey (USGS) data review that considers the state of knowledge regarding marine mineral occurrences within the Alaska OCS. This data release is a companion to the USGS Professional Paper, Gartman and...
