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.

Modeling marsh migration: User needs for decision-making collected in 2021 and 2023 Modeling marsh migration: User needs for decision-making collected in 2021 and 2023
The U.S. Geological Survey (USGS) conducted interviews of professionals who make decisions about marshes during the Salt Marsh Evolution along the South Atlantic Bight project (SAB project) and the Marsh Model Retrospective initiative. During the SAB project, an advisory committee of marsh model users were interviewed in June 2023 about what decisions they make about marshes and how they...
Extreme Flood, Atmospheric River Presence, and Basin Characteristic Data for a Study of Peak Streamflow Special Conditions in Alaska Extreme Flood, Atmospheric River Presence, and Basin Characteristic Data for a Study of Peak Streamflow Special Conditions in Alaska
This data release contains input data and results for an investigation of special conditions for peak streamflow and extreme floods for USGS streamgages in Alaska. Special conditions can include data-collection conditions, basin conditions, flood-generating mechanisms, or other information and can be critical for informing hydrologic analyses such as flood frequency analysis. The dataset...
Aquatic reflectance data from Sentinel-2 satellite imagery paired with continuous water quality measurements across the Delaware, Illinois, Trinity, Upper Colorado, and Willamette River basins in the United States from July 2015 through September 2024 Aquatic reflectance data from Sentinel-2 satellite imagery paired with continuous water quality measurements across the Delaware, Illinois, Trinity, Upper Colorado, and Willamette River basins in the United States from July 2015 through September 2024
Aquatic reflectance data from Sentinel-2 satellite imagery is paired with continuous water quality measurements across the Delaware, Illinois, Trinity, Upper Colorado, and Willamette River basins in the United States from July 2015 through September 2024. The dataset contains a zipped file (Matched_WQ_S2.zip) containing two csvs of matched continuous colored dissolved organic matter...
Small mammal captures in Everglades National Park, Florida (2014 - 2019) Small mammal captures in Everglades National Park, Florida (2014 - 2019)
Species differ in their habitat preferences based on seasonal hydrologic conditions. Species such as the semi-aquatic marsh rice rat (Oryzomys palustris) are adapted to high water conditions, while other species, such as the hispid cotton rat (Sigmodon hispidus) and the cotton mouse (Peromyscus gossypinus) prefer drier hammocks during the wet season. The aim of our study was to...
Stream Health and Habitat Assessments for Mixed Agricultural Streams in Pennsylvania and Maryland (2023) Stream Health and Habitat Assessments for Mixed Agricultural Streams in Pennsylvania and Maryland (2023)
U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 3rd of April to the 23rd of June in 2023, using various methods to record geomorphic and habitat indicators throughout 30 streams in southern Pennsylvania and northern Maryland. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and riparian analyses...
Elk Herd Unit Ecological Data for Northwestern Wyoming and Southwestern Montana in relation to Elk Feedgrounds from 1995-2020 Elk Herd Unit Ecological Data for Northwestern Wyoming and Southwestern Montana in relation to Elk Feedgrounds from 1995-2020
Data blended from a variety of sources to explore the effects of feeding on elk population productivity metrics with the incorporation of climate, predator, and harvest data over a 26-year time frame. Data are for elk herd units in northwestern Wyoming and two herd subunits for southwestern Montana.
