Riverine silicon (Si) plays a vital role in governing primary production, water quality, and carbon sequestration. The Global Aggregation of Stream Silica (GlASS) database was constructed to assess changes in riverine Si concentrations and fluxes, their relationship to available nutrients, and to evaluate mechanisms driving these patterns. GlASS includes dissolved Si (DSi), dissolved...

These are the northern long-eared bat (Myotis septentrionalis) summer month occupancy values derived from acoustic sampling and associated collection site environmental and weather covariates for the New England region, United States, 2015-2022.

The dataset is a 3 m spatial resolution Digital Elevation Model (DEM) representing terrain heights in northern Vicksburg, MS and Vicksburg National Military Park in 1962. The DEM was created using structure from motion-aided (SfM-aided) photogrammetry techniques in Agisoft Metashape (v 2.1.1). The aerial images were acquired on February 10, 1962 by the U.S. Department of Agriculture at

The dataset is a 0.5 m spatial resolution panchromatic (black and white - B&W) orthomosaic of northern Vicksburg, MS and Vicksburg National Military Park in 1938.The orthomosaic was created from aerial images acquired on June 14, 1938 by Pan American Aerial Surveys for the U.S. Department of Agriculture at approximately 1:20,000 scale by a Fairchild K-10 or similar aerial camera with 5in...

Marsh migration potential in the Chesapeake Bay (CB) salt marshes is calculated in terms of available migration area for each marsh unit defined by Ackerman and others (2022). The space available for landward migration is based on the NOAA marsh migration predictions under 2.0 feet of local sea-level rise (SLR). The migration space is further divided by National Hydrography Dataset (NHD)...

This data release presents cyanotoxin and multiparameter water-quality sonde data collected from July-October 2020, at eleven sites in the Salem River, New Jersey. Data-collection sites included seven flowing and four impounded reaches of the main stem Salem River. Solid Phase Adsorption Toxin Tracking (SPATT) samplers were deployed at 11 sampling locations during the study period and...

Efforts to improve water quality by changing the amount of nutrients in the water can affect fish habitats and fisheries. This makes it important to coordinate fishery management and water quality efforts, taking into account how fish behave in response to changes in their habitat. This data set combines information from acoustic telemetry, which tracks the movements of native lake...

Scientists and engineers from the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center (EROS) Cal/Val Center of Excellence (ECCOE) collected in situ measurements using field spectrometers to support the validation of surface reflectance products derived from Earth observing remote sensing imagery. Data provided in this data release were collected during select...

Post-fire vegetation structure and fuel data are needed to understand how an area recovers over time. To address this need, data were collected within the perimeter of the 2000 Jasper Fire near Custer, SD, on 73 plots co-located with plots previously established by scientists to assess burn severity. Vegetation structure data were collected at these plots during two periods: July 11–17...

This data release contains 22 horizontal-to-vertical spectral ratio (HVSR) seismic measurements at 21 sites in Franklin County, New York. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective technique for estimating the thickness of unconsolidated sediments over bedrock. This technique uses a single broadband three...

This data release contains 43 horizontal-to-vertical spectral ratio (HVSR) seismic measurements in Erie, Cattaraugus, and Wyoming Counties, New York collected between 2019 and 2023, in cooperation with the New York State Department of Environmental Conservation. The HVSR passive seismic method (Lane and others, 2008; Fairchild and others, 2013) is a non-invasive and cost-effective...

Underwater passive acoustic monitoring was conducted at multiple sites on rivers in the Willamette River Basin, Oregon. Hydrophones were used to record the sound associated with coarse river-bed sediment (bedload) movement. Bedload supply and transport are key factors determining channel morphology in gravel-bed rivers and can affect reach-scale conditions such as aggradation and...
