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.

Storm-Induced Coastal Change Forecasts: Louisiana Hurricanes Laura and Delta 2020 Storm-Induced Coastal Change Forecasts: Louisiana Hurricanes Laura and Delta 2020
These datasets contain information on the probabilities of storm-induced erosion (collision, overwash and inundation) on sandy beaches along the U.S. Gulf coast of Texas, Louisiana, Mississippi, and Alabama during hurricane impact conditions of Hurricanes Laura and Delta in 2020. The analysis is based on a storm-impact scaling model that uses observations of dune morphology combined with
Data acquired in laboratory experiments conducted to characterize Ag bioaccumulation kinetics in Daphnia magna after exposures to polystyrene microplastics and Ag nanoparticles Data acquired in laboratory experiments conducted to characterize Ag bioaccumulation kinetics in Daphnia magna after exposures to polystyrene microplastics and Ag nanoparticles
Microplastics (MPs) are an environmental concern. They can interact with other contaminants and pose new threats to organisms. We assessed the effect MPs on silver (Ag) bioaccumulation in the filter-feeding zooplankton Daphnia magna exposed to Ag nanoparticles at environmentally relevant concentrations.
Concentration results for per- and polyfluoroalkyl substances (PFAS) analyzed in fish tissue, bed sediment, and biofilm samples, Montana, 2023 Concentration results for per- and polyfluoroalkyl substances (PFAS) analyzed in fish tissue, bed sediment, and biofilm samples, Montana, 2023
This data release contains the concentration results of per- and polyfluoroalkyl substances (PFAS) collected in fish tissue and whole blood, bed sediment and biofilm samples from water bodies in and surrounding the Little Bighorn River (LBHR) in Montana in July 2023. A total of 29 filets and whole blood samples were collected from 10 brown trout, 10 catfish, 6 rock bass, and 3 goldeye...
LANDFIRE 2024 Update (ver. 2.0, March 2026) LANDFIRE 2024 Update (ver. 2.0, March 2026)
This product suite maintains LANDFIRE's ongoing goal to release annual updates every year that are current to the previous year. This means LF 2024 accounts for disturbances up through Fiscal Year 2024 and is being released in 2025. The releases are intended to provide critical, up-to-date information ahead of the fire season for areas of the United States prone to large devastating...
Observed reproductive status and estimated den entrance and emergence data for radio-marked females and estimated birth dates of offspring for four grizzly bear populations in North America, 2011-2021 Observed reproductive status and estimated den entrance and emergence data for radio-marked females and estimated birth dates of offspring for four grizzly bear populations in North America, 2011-2021
This data release contains the observed reproductive status and estimated den entrance and emergence data for 114 radio-marked female grizzly bears and the estimated birth dates of offspring for four populations in North America collected from 2011-2021. The studied populations inhabited the Greater Yellowstone Ecosystem, Northern Continental Divide Ecosystem, Selkirk and Cabinet-Yaak...
Model Archive Summary for Suspended-Sediment Concentration at station 06329500, Yellowstone River near Sidney, Montana, April 2022 through October 2024 Model Archive Summary for Suspended-Sediment Concentration at station 06329500, Yellowstone River near Sidney, Montana, April 2022 through October 2024
This model archive summary (MAS) and associated model calibration dataset documents the suspended-sediment concentration (SSC) model developed to compute 15-minute, near-real-time SSC at U.S. Geological Survey (USGS) streamgage station 06329500, Yellowstone River near Sidney, Montana (MT) for calendar years 2022-2024 and is the model currently in use. This model is specific to USGS site...
