Data

Here, we present data supporting temporal variability and sources of PFAS in the Rio Grande through an arid urban area using high-frequency sampling and novel samplers. Data are compiled into two tables: 1) full fluorescence spectra in vectorized format, and 2) summary file of concentrations of total dissolved nitrogen and commonly extracted field-based sensor arrays. Data are reported...

This data is comprised of representative chloride values Seneca and Cayuga Lakes and their tributaries from many sources.

This tabular data set contains information about the diets of angler-caught Lake Trout (Salvelinus namaycush), Walleye (Sander vitreus), Chinook Salmon (Oncorhynchus tshawytscha), Coho Salmon (O. kisutch), Atlantic Salmon (Salmo salar), Steelhead (O. mykiss), Pink Salmon (O. gorbuscha), and Brown Trout (Salmo trutta) captured between April and October of 2017 and 2018 from U.S. waters of...

These data consist of juvenile lake trout biological and diet information collected from USGS bottom trawl, beam trawl, and gillnet surveys in Lake Michigan from 2015-2017 and 2019-2022. All prey were identified, enumerated and weighed. Only fish prey and Mysis had lengths measured.

This data release includes Lake Ontario prey fish data including species captured, relative abundance, spatial distribution, size structure, and age data from the April or spring prey fish bottom trawl survey, 1978 through 2022. Data from 1978 - 2015 are from U.S. waters of Lake Ontario while data from 2016 - 2022 include both U.S. and Canadian waters of Lake Ontario. Details about the...

Acoustic seabed classification (ASC) is an important method for understanding landscape-level physical and biological patterns in the aquatic environment. Bottom habitats in the Laurentian Great Lakes are poorly mapped to date, and will require a variety of contributors and data sources to complete. We repurposed a long-term split-beam echosounder dataset gathered for purposes of...

This data release contains lakebed groundwater and surface-water temperatures collected during a survey on September 18, 2020, by using a handheld thermocouple probe at Shubael Pond, a groundwater flow-through kettle-hole pond, located in Marstons Mills, Massachusetts. The dataset includes a comma separated values (.csv) file, a geospatial dataset (shapefile), and FGDC-compliant metadata...

A validation assessment of Land Cover Monitoring, Assessment, and Projection Collection 1.3 annual land cover products (1985–2021) for the Conterminous United States was conducted with an independently collected reference dataset. Reference data land cover attributes were assigned by trained interpreters for each year of the time series (1984–2021) to a reference sample of 26,971 Landsat

In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey calculated four land cover basin characteristics rasters from the National Land Cover Database (NLCD) 2019 as part of updating the South Carolina StreamStats application. These datasets are raster representations of impervious surface, developed, forested, and storage land cover attributes...

These data were compiled to provide satellite remote sensing observations of landcover in the vicinity of wetlands fed by geothermal springs in Dixie Meadows, Nevada, USA. Objectives of the study were to map landcover of water, vegetation, and soil between October 5, 2015, and January 21, 2022, using available imagery from the Sentinel-2 mission. The U.S. Geological Survey's Southwest...

This update includes: responses to vegetation successional change in...

The LANDFIRE (LF) 2022 Update represents another step in moving towards an annual update. This update is the first time in LANDFIRE history in which disturbances from the year before are represented in current year products. LF 2022 includes adjustments to vegetation and fuels in disturbed areas for disturbances recorded in 2021 and 2022.
