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.

Model Archive Summary for acoustic derived suspended-sediment concentration at 14211720 Willamette River at Portland, OR (ver. 2.0, May 2025) Model Archive Summary for acoustic derived suspended-sediment concentration at 14211720 Willamette River at Portland, OR (ver. 2.0, May 2025)
This model archive summary describes techniques and methods used to derive and compute a second version of a suspended-sediment model at USGS site14211720, Willamette River at Portland. The created suspended-sediment concentration equations will be used to create real-time estimates of concentration and load which are available through the National Water Information System. The time...
Model Archive Summary for acoustic derived suspended-sand concentration at 14211720 Willamette River at Portland, OR Model Archive Summary for acoustic derived suspended-sand concentration at 14211720 Willamette River at Portland, OR
This model archive summary describes the development and methods used to derive and compute a suspended-sand (> 0.0625 mm particle size) model at USGS site ID# 14211720, Willamette River at Portland. The suspended-sand equations will be used to create real-time estimates of concentration and load that will help science entities, managers, and others, monitor sediment transport in the...
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...
