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.

Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River, Yolo Bypass, and Cache Slough Region, California, 2024 Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River, Yolo Bypass, and Cache Slough Region, California, 2024
Zooplankton samples were collected in the summer/fall of 2024 at multiple sites in the Sacramento River, Yolo Bypass, and Cache Slough Region of California and analyzed for a suite of 160 current-use pesticides and pesticide degradates by the U.S. Geological Survey Organic Chemistry Research Laboratory. Samples were collected at two sites in the Bypass, at a comparison site on the...
Stable carbon (C13) and nitrogen (N15) isotopic values of American alligators within the Florida Everglades (2013-2020) Stable carbon (C13) and nitrogen (N15) isotopic values of American alligators within the Florida Everglades (2013-2020)
This dataset contains morphometric and isotopic data for American alligators (Alligator mississippiensis) that were sampled from within four freshwater (FW) wetlands and one estuarine (EST) wetland within the Greater Everglades ecosystem. Due to their compartmentalization and varied habitat and water regimes, there were multiple sampling sites within two of the FW wetlands. The five...
Data for the evaluation of the acute toxicity of 4-nitro-3-(trifluoromethyl)phenol (TFM) to Burbot (Lota lota) Data for the evaluation of the acute toxicity of 4-nitro-3-(trifluoromethyl)phenol (TFM) to Burbot (Lota lota)
The dataset provides access to all data used in the interpretation of results for the study including dose response curves from toxicity tests, predicted minimum lethal concentration data, water quality data, and mortality data.
Summary from posterior distributions of multistate movement model for silver carp in the upper Mississippi River from 2014 to 2021 Summary from posterior distributions of multistate movement model for silver carp in the upper Mississippi River from 2014 to 2021
This data contains the mean and standard deviations for movement rates for silver carp in the upper Mississippi River 2014 and 2021. The data are summaries of the posterior distribution from a Bayesian multistate model described in Stanton et al. 2024 (https://doi.org/10.7717/peerj.17834). References: Stanton JC, Brey MK, Coulter AA, Stewart DR, Knights B. 2024. Bayesian multistate...
The influence of fire-fuel feedbacks on boreal forest fire regimes under future climate change The influence of fire-fuel feedbacks on boreal forest fire regimes under future climate change
This data release contains a set of 21st-century burned-area projections to explicitly account for fire-fuel feedbacks in boreal North America for the years 2010 - 2100. Wildfire regimes in the boreal forest biome of North America are vulnerable to shifts in climate, and significant intensifications in area burned are anticipated under many 21st-century global climate model (GCM)...
Microfocus X-ray computed tomography measurements of ostracode Paracyprideis pseudopunctillata from the Beaufort Sea Microfocus X-ray computed tomography measurements of ostracode Paracyprideis pseudopunctillata from the Beaufort Sea
This dataset includes measurements of shell properties (e.g. density, volume, and weight) of the ostracode species Paracyprideis pseudopunctillata (subphylum Crustacea), which inhabits the continental shelves of the Arctic Ocean. Using microfocus X-ray computed tomography (microXCT) scans, we generated detailed morphometric measurements of specimens collected from both surface and down...
Water withdrawals in Louisiana, 2020 Water withdrawals in Louisiana, 2020
Information concerning the availability, use, and quality of water in the 64 parishes of Louisiana is critical for water-supply management. In cooperation with the Louisiana Department of Transportation and Development, the U.S. Geological Survey (USGS) Lower Mississippi-Gulf (LMG) Water Science Center (WSC) has been collecting, compiling, and publishing water-withdrawal and water-use...
Geologic map database of the Bison Range and vicinity, northwestern Montana Geologic map database of the Bison Range and vicinity, northwestern Montana
This data release provides Geologic Map Schema (GeMS)-compliant GIS data for new geologic mapping of the Bison Range and surrounding area on the Flathead Reservation, northwestern Montana. The database represents the geology for the 150 square kilometer, geologically complex map area, at a publication scale of 1:24,000. The map covers parts of Sanders and Lake Counties, Montana. All...
Hawai‘i Volcanoes National Park, Barcoding of Ambrosia Beetles and Wood-boring Lepidoptera Larva, 2021-2023 Hawai‘i Volcanoes National Park, Barcoding of Ambrosia Beetles and Wood-boring Lepidoptera Larva, 2021-2023
Ambrosia beetles (Coleoptera: Curculionidae) have been implicated in the spread of Ceratocystis fungi that cause rapid ‘ōhiʻa death (ROD), a deadly fungal disease threatening the keystone Hawaiian tree ʻōhiʻa lehua (Metrosideros polymorpha). Research has investigated the role that ambrosia beetles play in the spread of the disease, including studies within Hawaiʻi Volcanoes National Park...
Model Archive Summary for Turbidity Derived Suspended-Sediment Concentration at 14179000 Breitenbush River above French Creek near Detroit, Oregon Model Archive Summary for Turbidity Derived Suspended-Sediment Concentration at 14179000 Breitenbush River above French Creek near Detroit, Oregon
This document describes a new equation for estimating suspended-sediment concentration (SSC) at a fixed point from turbidity values at continuous 15-minute intervals and daily suspended sediment load at USGS site Breitenbush River above French Creek near Detroit, Oregon. The methods described follow USGS guidance as referenced in USGS Techniques and Methods, Book 3, Chap. C2 (Edwards and...
Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada Data release for Effects of Total Suspended Solids on Photomineralization of Dissolved Organic Matter in the Peace-Athabasca Delta, Canada
Northern deltas receive chromophoric dissolved organic matter (CDOM) from their watersheds, which can be oxidized to carbon dioxide upon absorption of sunlight (i.e., photomineralized). These deltas also receive total suspended solids (TSS), which may shade sunlight absorption by CDOM, thus limiting photomineralization. To quantify this interaction for the first time, we measured
Forest biomass projections under alternative management and hydrological scenarios in the Reno Bottoms area of the Upper Mississippi River floodplain Forest biomass projections under alternative management and hydrological scenarios in the Reno Bottoms area of the Upper Mississippi River floodplain
Floodplain forests are being transformed by multiple pressures, prompting widespread management and restoration efforts. It is uncertain how disturbances, including hydrologic change, and management actions will interact to influence the ecology of these threatened forests. Here, we present the results of a forest landscape model in support of an ecological study detailed in the...
