Little Rock Reservoir, California, 2022 bathymetric survey and stage-storage computations Little Rock Reservoir, California, 2022 bathymetric survey and stage-storage computations
This bathymetric dataset provides an update to the stage-storage relation for Little Rock Reservoir located in the Angeles National Forest, California. Bathymetric data was collected using a multibeam echo sounder to provide near-complete coverage and was merged with U.S. Geological Survey 3D Elevation Project lidar to compute a digital elevation model (DEM) of the reservoir and...
Cyanotoxin, chlorophyll-a, and cyanobacterial toxin genetic data for samples collected at twelve large river sites throughout the United States, June through October 2019 Cyanotoxin, chlorophyll-a, and cyanobacterial toxin genetic data for samples collected at twelve large river sites throughout the United States, June through October 2019
This U.S. Geological Survey (USGS) data release provides discretely measured cyanotoxin, chlorophyll-a, and cyanobacterial toxin genetic data for samples collected from twelve large river sites throughout the United States, from June through October 2019. Discrete water-quality samples were analyzed for cyanotoxins (anatoxin, cylindrospermopsin, microcystin, and saxitoxin), chlorophyll-a...
Physicochemical measurements of the coastal aquifer and coastal groundwater discharge on Kalaupapa, Moloka'i, Hawaii Physicochemical measurements of the coastal aquifer and coastal groundwater discharge on Kalaupapa, Moloka'i, Hawaii
This data table includes in-situ near-shore seawater measurements of excess radon (Rn-222), tide and crater lake water levels and salinity collected in Kalaupapa, Moloka'i, Hawaii.
County-level maps of cropland surface water inundation measured from Landsat and MODIS County-level maps of cropland surface water inundation measured from Landsat and MODIS
This dataset represents a summary of potential cropland inundation for the state of California applying high-frequency surface water map composites derived from two satellite remote sensing platforms (Landsat and Moderate Resolution Imaging Spectroradiometer [MODIS]) with high-quality cropland maps generated by the California Department of Water Resources (DWR). Using Google Earth Engine...
Borehole data for pre-Cretaceous basement rocks beneath the Atlantic Coastal Plain, Georgia and South Carolina Borehole data for pre-Cretaceous basement rocks beneath the Atlantic Coastal Plain, Georgia and South Carolina
Data from 391 boreholes (including coreholes) that penetrated buried pre-Cretaceous basement rocks that lie beneath Atlantic Coastal Plain sedimentary deposits in Georgia and South Carolina were compiled from non-proprietary, mostly published sources in order to support subsurface geologic mapping, geologic interpretation of geophysical data (aeromagnetic, gravity, seismic), topical...
Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, Taxodium distichum growth Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, Taxodium distichum growth
In 2013 five Taxodium distichum trees along a 125 m long transect of Hickory Point State Forest outside Pocomoke City, Maryland were outfitted with dendrobands. Each year the growth of the T. distichum trees was measured in terms of the ratio of that year's circumference to the previous year's circumference. Tree growth was measured until the year the tree died or the conclusion of the...
