This model archive summary documents the suspended sand (grain sizes > 0.0625mm) concentration model developed to compute 5-minute suspended sand concentration data of the Columbia River at Port Westward, near Quincy, OR, U.S. Geological Survey (USGS) site number 14246900. The methods used follow USGS guidance as referenced in USGS Techniques and Methods, Book 3, Chap. C2 (Edwards and...

This model archive summary documents the suspended sediment concentration (SSC) model (version 2.0) developed to compute 5-minute SSC data of the Columbia River at Port Westward, near Quincy, OR, U.S. Geological Survey (USGS) site number 14246900. The methods used follow USGS guidance as referenced in USGS Techniques and Methods, Book 3, Chap. C2 (Edwards and others, 1999); Office of...

These data support a study modeling the growth, capture, and survival of giant gartersnakes (Thamnophis gigas). We captured giant gartersnakes inhabiting rice irrigation canals in the Sacramento Valley, California, USA from 2018 to 2023. We analyzed capture-mark-recapture data from 19 populations of giant gartersnakes sampled with an integrated growth-survival model. We tested how growth...

The dataset includes the coordinates, collection year, age, band number, studbook number, and 54 microsatellite genetic markers for 186 individual light-footed Ridgway's rails, Rallus obsoletus levipes.

The datasets presented here include the Climate Priming Index, degree-day, and seasonal precipitation data used as inputs to the index for the state of Alaska. The data is presented for two time periods: a historic period from 1901-2020, and a projected period from 2000-2100 using 3 climate scenarios. The climate priming index was developed to identify years where the climatic conditions...

This data release provides concentration results for per- and polyfluoroalkyl substances (PFAS) collected by volunteer community members, in tapwater samples from 83 private residences, in select areas within the United States. Samples were collected July 1, 2023, through November 10, 2023. Samples were analyzed at the U.S. Geological Survey National Water Quality Laboratory (NWQL) in...

This dataset consists of repeat vegetation cover maps of multiple Willamette River restoration sites where restoration activities were implemented to increase the area of floodplain forests. Beginning in the early 21st century, large-scale restoration programs have been implemented along the Willamette River, Oregon, to address historical losses of floodplain habitats for native fish...

A three-dimensional groundwater flow model of the Central Valley in California was developed to aid water managers in understanding how water moves through the aquifer system, to predict water-supply scenarios, and to address issues related to subsidence. The USGS California Water Science Center made a detailed assessment of groundwater availability of the Central Valley aquifer system...

The dataset is composed of two data tables containing information from boat electrofishing surveys conducted during 2021, 2023, and 2024 in sections of the Mohawk River where it runs separately from the New York State Canal System (i.e., is not canalized). The first table contains fish collection data and the second table contains information on the sampled reaches.

This metadata record contains one table and one shapefile with results from field sampling at locations of groundwater discharge (seeps) identified by autonomous boat survey at the Lower Darby Creek Area (LDCA) Superfund Site, near Folcroft, Pennsylvania, in 2024. Included in the dataset are (1) PFAS concentrations, volatile organic compound (VOC) concentrations, cations/trace metals...

This dataset, collected and prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS - SPCMSC), includes sea turtle nesting decision point locations and cross-shore beach profiles at those locations. The data were collected by a person walking with a survey backpack equipped with a Global Positioning System (GPS) receiver and GPS antenna. The surveys...

In Louisiana, the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) identifies, prepares, and funds coastal wetland restoration projects. In the Evaluation Report to Congress to be submitted in 2024, geospatially driven visualizations are required to provide conceptual understanding of funded project sizes and locations as they pertain to the geographical region in...
