Data Releases

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Biofouling and mussel growth from mussels deployed in Great Lakes embayments (2013-2016)

Many taxa of North American unionid mussels are imperiled due to biofouling by invasive dreissenid mussels. Here, we report on biofouling rates of unionid mussels suspended in cages during the growing season in nearshore embayments in Lake Erie (2013-2016), Lake Michigan (Green Bay 2016, Grand Traverse Bay 2015) and Lake Huron (Saginaw Bay 2015). Mussels were deployed in early summer (late May or

Water chemistry and biological data of Rainbow Trout following aquatic exposure to weathered wildland fire retardants after application to substrate

We investigated whether the length of time fire chemical weathers on a terrestrial substrate before mixing into aquatic environments alters the chemical’s toxicity when encountered by juvenile rainbow trout. We also looked at whether the type of substrate where the chemical is applied affects its toxicity to juvenile rainbow trout after mixing into water. Two fire chemicals (Phos Chek LC95A-R and

Permethrin concentrations on sawgrass collected from National Key Deer Refuge in 2015

Sawgrass (Cladium jamaicense) samples were collected from marshes on five different keys (Big Pine, Torch, Ramrod, Cudjoe, and Sugarloaf Keys) within National Key Deer Refuge in January and June of 2015 and analyzed for contamination by the mosquito control insecticide permethrin. Permethrin was detected on 17 of 57 samples collected in January while it was detected on 40 of 56 samples collected i

Data and model archive used to model and map lithium concentrations in groundwater sources of drinking water in the conterminous United States

This data release contains data used to develop models and maps that estimate the occurrence of lithium in groundwater used as drinking water throughout the conterminous United States. An extreme gradient boosting model was developed to estimate the most probable lithium concentration category (≤4, >4 to ≤10, >10 to ≤30, or >30 µg/L). The model uses lithium concentration data from wells located th

U.S. Geological Survey National Produced Waters Geochemical Database (ver. 3.0, December 2023)

During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential

Bathymetry of Buckhorn Lake, Kentucky, May 2023

These data are bathymetry (lake bottom elevation) in XYZ format (Easting, Northing, Elevation), generated from the May 30–June 1, 2023, bathymetric survey of Buckhorn Lake, Kentucky, from the dam to CR-1475 (19.5 miles total reach length). Hydrographic data were collected using a RESON 210 kHz NaviSound single-beam echosounder (SBES) with a Hemisphere A222 integrated global navigation satellite sy

Movement Data for Migrating Geese Over the Northeast Pacific Ocean, 2018-2021

This dataset consists of one table with a record (row) for each goose location and columns containing location information and covariates. The dataset was used in an analysis of altitude selection and flight propensity in an accompanying paper (Weiser et al. 2024) and is being provided here to allow replication of that analysis. Goose locations (latitude, longitude, and altitude) were collected wi

DNA sequences used to analyze evolutionary rates of genes in bats

The dataset consists of sets of orthologous gene sequences obtained from the National Center for Biotechnology Information (NCBI, www.ncbi.nlm.nih.gov) and from Cornman and Cryan (2022). Sequences derive from twelve bat species that are representative of bat diversity and for which high-quality gene models have been annotated. Each gene set was codon aligned and subsequently trimmed as needed for

Target-Chemical Concentrations for Assessment of Mixed-Organic/Inorganic Chemical and Biological Exposures in Private-Well Tapwater at Campbell, Wisconsin, 2021

Tapwater samples were obtained from groundwater sources on French Island, in the town of Campbell, Wisconsin. Samples from three locations were collected multiple times over a period of three days to assess temporal variations in water quality. Samples from an additional eight locations, were collected one time, spatially distributed around Campbell. Due to privacy concerns, the exact location of

Video acquired from an Uncrewed Aerial System, UAS, and hydroacoustic measurements of flow velocity obtained along the North Santiam River, Oregon, in July 2022

A reach of the North Santiam River, Oregon, was used as a case study in an ongoing effort to develop and test image velocimetry algorithms for estimating surface flow velocities in river channels from remotely sensed data. Video was acquired from an unoccupied aircraft system, UAS, and used as input to the image velocimetry algorithms. Direct measurements of flow velocity were obtained using an ac

Geospatial representations of salinity monitoring site and bay and estuary group boundaries in the Gulf of Mexico

The polygon datasets were created to assist in visualizing the results of salinity modeling in Gulf of Mexico estuaries and bays. Statistical algorithms (Asquith and others, 2023) were developed to predict daily salinities for 91 salinity monitoring sites (Rodgers and Swarzenski, 2019) operated by 7 agencies in near coastal United States waters of the Gulf of Mexico. These monitoring sites are ass

Microsatellite genotypes of Bombus occidentalis specimens (including Bombus mckayi) from 1960 to 2020

This dataset consists of the microsatellite genotypes, collection data, and ownership data for 1461 specimens of Bombus occidentalis. The dataset includes both recognized subspecies, Bombus occidentalis occidentalis and Bombus occidentals mckayi. The subspecies have since been elevated to species status and are currently described as Bombus occidentalis and Bombus mckayi. The specimens were collec
