This data release makes available the data used to test a method for remote sensing of river discharge based on critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, simple measurements of the wavelengths of the standing waves and the width of the channel made using readily available image data can be used to infer river...

This data release includes metadata and tabular data that documents the distribution of yellow crazy ants (Anoplolepis gracilipes) across Wake Atoll. The three islands that comprise the atoll were systematically searched by hand. The dataset describes the outcome of searching 3,675 cells, each 50 x 50 m in size, during 6-21 October 2023. .

This data release contains a point cloud and raster image of a digital surface model (DSM) that covers a portion of the Lost River fault in Idaho that ruptured in the 1983 M6.9 Borah Peak earthquake. The DSM provides a high-resolution, pre-earthquake record of the landscape from 1966. It is constructed using structure-from-motion photogrammetry software and aerial photographs taken in...

This data set describes serological data collected from mammals in Alaska and seropositivity to influenza A, clade 2.3.4.4b H5 highly pathogenic avian influenza (HPAI), North American lineage H5 low pathogenic avian influenza (LPAI), and N1 antigens.

Unprecedented wildfire frequency fueled by invasive annual grasses threatens sagebrush habitats. To suppress fire and conserve sagebrush, land management agencies have installed ~10,000 km of fuel breaks across the sagebrush ecosystem. The ecological risks and benefits of creating fuel breaks for wildfire suppression are unquantified but must be balanced to avoid accelerating sagebrush...

This data release includes metadata and tabular data from a field study of avian diseases (malaria and pox virus) that threatened recovery of the last extant population of ‘Alalā (Corvus hawaiiensis) before it went extinct in the wild in the early part of the 21st century. The study focused on habitat occupied by the last remaining wild ‘Alalā and determined prevalence of avian malaria...

This dataset contains a point cloud (Slumgullion_PointCloud.laz), 1-meter digital surface model (Slumgullion_DSM.tif), and orthoimagery (0.1-meter resolution) (Slumgullion_Ortho.tif) of the active portion of the Slumgullion landslide in Lake City, Colorado. The Slumgullion landslide is a translational slide with a continuously moving, active portion and an inactive portion. 896 photos...

This data release contains 16 variables from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS) modeling application forced with Daymet version 4 (Rosa and others, 2025) from 1980 through 2021 that are summarized to a monthly time step and a twelve-digit hydrologic unit code for the spatial extent of Hawaii. The following fluxes and...

Determining how much methane and carbon dioxide cross the sea-air interface is critical when assessing marine greenhouse gas fluxes. This assessment is particularly important on Arctic Ocean continental margins, where rapid climate change is thawing glacial ice and permafrost; reducing sea ice cover; and changing water temperatures, salinities, nutrient loads, and ocean currents. This...

In November 2021, the U.S. Geological Survey collected high-resolution multibeam sonar data in the vicinity of Eel Pond, in Woods Hole, Massachusetts using a dual-head Teledyne Seabat T20-R multibeam echo sounder (MBES). The main objective of this survey was to evaluate new sonar system features prior to their use in future field activities. In addition to bathymetry and relative...

Small Uncrewed Aircraft Systems (sUAS) were used to collect aerial remote sensing data over Marsh Island, a salt marsh restoration site along New Bedford Harbor, Massachusetts. Remediation of the site will involve direct hydrological and geochemical monitoring of the system alongside the UAS remote sensing data. Baseline conditions were evaluated in October 2023, and future data...

This data release contains coastal wetland synthesis products for the Atlantic-facing New Jersey salt marshes. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, and tidal range, are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health.
