Data Releases

Data on carbon and nutrient processing in key locations and over seasonal time scales can provide critical information about the concentrations and potential utilization rates of bioavailable constituents that are known to have a role in cyanobacteria harmful algal blooms (cyanoHABs). Laboratory experiments were performed to measure seasonal nutrient processing rates of carbon, nitrogen...

Microplastics, per- and polyfluoroalkyl substances (PFAS), antibiotic resistance genes (ARGs), pharmaceuticals and personal care products (PPCPs), and pesticides cause unintentional environmental contamination through many pathways in multiple matrices. This statewide, multi-matrix study examined multiple contaminants of global concern (CGCs) in water, bed sediment, and fish to...

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the bedrock geologic map of the Beans Cove and Hyndman quadrangles and part of the Fairhope quadrangle (de Witt, 1974). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in the...

Non-native Phragmites australis is one of the most aggressive plant species invading North America and is managed using a suite of conventional approaches (e.g., herbicide, cutting/crushing, flooding, burning). These management actions are resource intensive and differ in effectiveness, largely because there are uncertainties about how the plant responds to treatment given site-specific...

This dataset represents the locations of experimental plots that were used during the Phragmites bioherbicide 2024 field experiment, where a novel bio-based formula for herbicide was applied to Phragmites australis to test the efficacy of Phragmites bioherbicide as a tool to control invasive Phragmites. To meet the criteria for selection, a site must have relatively dry soil with no...

Laser ablation inductively coupled mass spectrometry was used to quantify Strontium:Calcium of the core of each otolith and classified each fish to a natal origin (i.e., tributary or potential resident). Predator fishes of focus were Bowfin and Largemouth Bass from the Upper Mississippi River (Pools 4, 8, and 13). Any use of trade, firm, or product names is for descriptive purposes only...

This data release contains modeled estimates of chlorophyll a concentration and cyanoHAB occurrence for a subset of lakes in New York State. Estimates of chlorophyll a concentration were generated using a random forest model. Estimates of cyanoHAB occurrence were generated based on thresholds derived from bootstrapped logistic regression. All analysis was done in R 4.4.1 (R Core Team...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional and continuous oil and gas resources in the Los Angeles Basin Province, California. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within...

The U.S. Geological Survey collected groundwater samples from 44 wells used for domestic and small system drinking water supplies in the western Central Valley, California in 2023. The wells were sampled for the Western Central Valley domestic-supply aquifer study unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin...

This dataset includes fish population and habitat data collected in 2024 to support development of the upper Santa Ana River Habitat Conservation Plan for the Santa Ana Sucker (Catostomus santaanae) and the Arroyo Chub (Gila orcuttii) in the Santa Ana River, California.

This GIS shapefile, "density_contours," describes 1) a bison study area at Tallgrass Prairie National Preserve, Kansas, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2021-2023. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the

This GIS shapefile, "density_contours," describes 1) a bison study area at Wind Cave National Park, South Dakota, and 2) 25%, 50%, 75%, and 99% kernel density contours for locations of bison marked with GPS collars during 2019-2024. Percentages associated with contours describe nominal coverage, i.e., proportions of observations they are expected to encompass, and approximate the...
