The U.S. Geological Survey (USGS), in partnership with several federal agencies, has now developed and released seven National Land Cover Database (NLCD) products: NLCD 1992, 2001, 2006, 2011, 2016, 2019, and 2021. Beginning with the 2016 release, land cover products were created for two-to-three-year intervals between 2001 and the most recent year. These products provide spatially...

The National Petroleum Reserve-Alaska (NPRA) Legacy Data Archive contains geological and geophysical data collected during two extensive exploration programs, operated first by the U.S. Navy (1944-1953) and later by the U.S. Geological Survey (USGS) (1974-1982). This dataset includes records from 36 test wells, 45 core tests, and over 12,000 line miles of seismic data, along with a wide...

National-scale geologic, geophysical, and mineral resource raster and vector data covering the United States, Canada, and Australia are provided in this data release. The data were compiled as part of the tri-national Critical Minerals Mapping Initiative (CMMI). The CMMI, established in 2019, is an international science collaboration between the U.S. Geological Survey (USGS), Geoscience

Lake trophic status is a key water quality property that integrates a lake's physical, chemical, and biological processes. Despite the importance of trophic status as a gauge of lake water quality, standardized and machine readable observations are uncommon. Remote sensing presents an opportunity to detect and analyze lake trophic status with reproducible, robust methods across time and...

Data are fish species occurrences in surveys made by backpack electrofishing and seining in shoal habitats in the Etowah River downstream from Allatoona Dam (n=10 surveys in 2010 and n=5 surveys in 2016; 20 taxa total) and in the Coosawattee River downstream from Carters Dam and re-regulation dam (n=11 surveys in 2010; 32 taxa total), Georgia, USA. Data for the Etowah River include...

This dataset includes the behavioral fish data needed to assess the responses of Upper Mississippi River fishes to an acoustic stimulus (i.e., playback of a 100 hp boat motor). Native ostariophysians (bigmouth buffalo Ictiobus cyprinellus, channel catfish Ictalurus punctatus, and fathead minnow Pimephales promelas), invasive ostariophysians (bighead carp Hypophthalmichthys nobilis...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River and St. Lucie River July 13-15, 2020 and the Caloosahatchee River September 22 and 23 of 2019, south Florida. The St. Lucie portion of the surveys was not able to be completed in September due to boat engine failure. Geo-referenced measurements of near surface water

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River on June 21-22 and July 20, 2021, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and fluorescence of dissolved organic matter...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the Caloosahatchee River, St. Lucie River and Lake Okeechobee July 15-18 and August 19-21 of 2019, south Florida. Geo-referenced measurements of near surface water temperature, specific conductance, dissolved oxygen, pH, turbidity, chlorophyll fluorescence, phycocyanin fluorescence, and...

This U.S. Geological Survey (USGS) Data Release provides spatial water-quality data collected from the St. Lucie and Caloosahatchee Rivers in October 2017, Lake Okeechobee and the Caloosahatchee River in July 2018 and the Caloosahatchee River, St. Lucie River and Lake Okeechobee in August of 2018, south Florida. Geo-referenced measurements of near surface water temperature, specific...

This dataset includes daily nest attendance (proportion of time females spent at the nest), incubation constancy (proportion of time females maintained their nests at nest-specific incubation temperatures), nest temperature variation, and the duration of individual incubation bouts for three species of dabbling ducks (mallard, gadwall, and cinnamon teal) nesting in Suisun Marsh...

In 2021 the United States Geological Survey (USGS) sampled the lower part of the Upper Cretaceous Lewis Shale in the eastern part of the Southwestern Wyoming Province to better characterize its petroleum source rock potential for an upcoming resource assessment. Ninety-five samples from 24 wells were collected from well cuttings of the lower part of the Lewis Shale stored at the U.S...
