Associated data for the Triangle Area Water Supply Monitoring Project, North Carolina, October 2017 - September 2019 Associated data for the Triangle Area Water Supply Monitoring Project, North Carolina, October 2017 - September 2019
These datasets contain information used to compile the report (USGS OFR 2020-xxxx). It contains water-quality data, analytical results of field blanks, and analytical results for environmental and replicate sample sets for surface-water samples collected during water years 2018 and 2019 for the Triangle Area Water Supply Monitoring Program (TAWSMP).
Ecological Potential Fractional Component Cover Based on Long-Term Satellite Observations Across the Western United States Ecological Potential Fractional Component Cover Based on Long-Term Satellite Observations Across the Western United States
Rangelands have immense inherent spatial and temporal variability, yet assessments of land condition and trends are often assessed relative to the condition of a limited number of representative points. Ecological Potential (EP) data are spatially comprehensive, quantitative, and needed as a baseline for comparison of current rangeland vegetation conditions, trends, and management...
Beach topography and near-shore bathymetry of Lake Superior at Minnesota Point and the Duluth Entry, Duluth, MN, 2020 (ver. 2.0, September 2024) Beach topography and near-shore bathymetry of Lake Superior at Minnesota Point and the Duluth Entry, Duluth, MN, 2020 (ver. 2.0, September 2024)
This dataset represents elevation data of the beach topography and near-shore bathymetry of Lake Superior at two locations along Minnesota Point, Duluth, Minnesota. LiDAR data were collected using a Velodyne VLP-16 unit representing the beach topography, and multibeam sonar data were collected using a Norbit integrated Wide Band Multibeam System compact (iWBMSc) sonar for bathymetry. The...
Bathymetric and water quality data on the Sandusky River between Tiffin and Fremont, Ohio, November 4-7, 2019 Bathymetric and water quality data on the Sandusky River between Tiffin and Fremont, Ohio, November 4-7, 2019
On November 4-7, 2019, bathymetric data were collected on the Sandusky River between Tiffin and Fremont, Ohio. Wading measurements were made at cross-sections shallower than about 1 foot using a survey pole with a Trimble R10 Global Navigation Satellite System (GNSS) receiver connected to the Ohio Department of Transportation (ODOT) real-time virtual reference station (VRS) network...
Spatial and bathymetric data for Lago Patillas, Puerto Rico, August 2019 Spatial and bathymetric data for Lago Patillas, Puerto Rico, August 2019
Metadata for this geodatabase describe datasets included in the bathymetric study completed for Lago Patillas in August 2019. The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, carried out a bathymetric survey to update stage-volume table for Lago Patillas and to generate a bathymetric map. Water-depth data were collected using a bathymetric data...
Fish community and substrate data from tributaries to the Mohawk River (ver. 2.0, January 2024) Fish community and substrate data from tributaries to the Mohawk River (ver. 2.0, January 2024)
The dataset is composed of three data tables containing information from electrofishing and pebble count surveys conducted in tributaries to the Mohawk River in central and eastern New York during 2019 and 2023. 20 sites were surveyed in 2019, and 19 of those same sites were resurveyed in 2023. The first table contains information on the sampled reaches, the second table contains fish...
