Modeled transport components of daily chlorophyll-a in the Illinois River, 2018 through 2020 (version 1.1, April 2024) Modeled transport components of daily chlorophyll-a in the Illinois River, 2018 through 2020 (version 1.1, April 2024)
TThis data release contains approximately three years of modeled chlorophyll-a—a proxy for planktonic algal biomass—transport through a 394-km portion of the Illinois River. Defined by four distinct reaches, model estimates include daily water balance, velocities, and algal biomass separated into its components of net growth, net loss, transported from upstream, and input from...
Thermal Infrared Images of Groundwater Seeps in the Upper Shawsheen River Watershed, Massachusetts Thermal Infrared Images of Groundwater Seeps in the Upper Shawsheen River Watershed, Massachusetts
This USGS data release contains datasets and metadata associated with identifying locations of groundwater seepage to streams in the Upper Shawsheen River Watershed in Massachusetts. Data were collected in August 2023 to characterize the spatial distribution of groundwater seeps along streambanks within Elm Brook, Hartwell Brook, and the Shawsheen River. Discharge measurements were made...
Nearshore wave time-series along the coast of Alaska computed with a numerical wave model Nearshore wave time-series along the coast of Alaska computed with a numerical wave model
Alaska's Arctic coast has some of the highest erosion rates in the world. Erosion in the Arctic is primarily driven by permafrost thaw and wave activity. The warming climate decreases sea ice coverage, resulting in an increase in wave energy. To overcome the lack of available observational wave data in the nearshore, waves were downscaled with a numerical wave model (SWAN) utilizing...
Aerial imagery and other remotely-sensed data from a UAS survey of Pepperwood Preserve, Sonoma County, CA Aerial imagery and other remotely-sensed data from a UAS survey of Pepperwood Preserve, Sonoma County, CA
This data release contains Uncrewed Aircraft System (UAS) imagery from three data collection campaigns (flights) over the Pepperwood Preserve in Sonoma County, California. Each child item contains: 1) Orthophoto, 2) Thermal, 3) Normalized Difference Vegetation Index (NDVI), 4) L-band microwave brightness temperature (Tb), 5) Estimated soil moisture, and 6) Digital elevation model from...
Vertical Profiles and Near Surface Water Quality Transects for Dissolved Oxygen Monitoring of the Arthur Kill, New York and New Jersey, September 7th and 8th, 2023 Vertical Profiles and Near Surface Water Quality Transects for Dissolved Oxygen Monitoring of the Arthur Kill, New York and New Jersey, September 7th and 8th, 2023
Transects of near-surface continuous water-quality data and vertical profiles of the same parameters were collected over a 24-hour period from September 7 to September 8, 2023 in the Arthur Kill. The Arthur Kill is a tidal strait located between Staten Island, New York, and Union and Middlesex Counties, New Jersey, and connects Newark Bay to the north and Raritan Bay to the south. It is...
Geospatial Datasets of the Glacial Geology and Hydrogeology of the Owasco Inlet Watershed, Cayuga and Tompkins Counties, New York Geospatial Datasets of the Glacial Geology and Hydrogeology of the Owasco Inlet Watershed, Cayuga and Tompkins Counties, New York
In 2015, the U.S. Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), began an appraisal of the sand and gravel aquifers within the Owasco Inlet watershed, which covers about 117 square miles (mi2) and drains north directly to Owasco Lake, one of New York’s Finger Lakes. About three-quarters of the watershed is within Cayuga...
