This model archive documents the Soil-Water-Balance (SWB) model used to simulate potential recharge for portions of Pennsylvania and Maryland from 2000 to 2021. The Pennsylvania and Maryland SWB model was used to create output at a 250 meter grid scale. Model parameters were adjusted using baseflow estimates from 36 reference watersheds varying in area from 0.37 to 817 square miles. The simulation

The Kalamazoo River Area of Concern (AOC) in Michigan has multiple dams in various stages of removal. Following dam removal, river restoration activities will occur in impacted reaches. Hydrogeomorphic data from relatively undisturbed and hydraulically stable river reaches are commonly used to inform the design parameters of river restoration projects. Reference reaches should be selected that ope

Viral hemorrhagic septicemia virus (VHSV) is an aquatic rhabdovirus causing severe disease in numerous freshwater and saltwater fish species. Initially the virus was been found to cause disease in European fish populations starting around 1938 and was first detected in North America in the late 1980s. Of the four VHSV genotypes (I, II, III, and IV), the North American subtype IVb isolates have a b

An ecological study on mercury contamination in the wetland of West Dongting Lake in China. This study measured the total mercury concentration in the soil and compared it to the measured total concentration of mercury in the above and below ground tissue of different plant species on the floodplain of West Dongting Lake. Bioconcentration, bioaccumulation, and translocation factors were determined

High-frequency observations of surface water at fine spatial scales are critical to effectively manage aquatic habitat, flood risk and water quality. We developed inundation algorithms for Sentinel-1 and Sentinel-2 across 12 sites within the conterminous United States (CONUS) covering greater than 536,000 km2 and representing diverse hydrologic and vegetation landscapes. These algorithms were trai

Bathymetric data were collected with a single-beam echosounder in 2022 for 18 selected shallow (0-3 meters) areas to improve a digital elevation model (DEM) for Rainy Lake and Namakan Reservoir created by Environment and Climate Change Canada. Bathymetric data were collected in transects spaced approximately 20 meters apart. In addition to the bathymetric data, the locations and elevations of obse

This data release supports the paper titled, "Insights into the metamorphic history and origin of flake graphite mineralization at the Graphite Creek graphite deposit, Seward Peninsula, Alaska, USA", published in the journal Mineralium Deposita. The data release includes zircon and titanite U-Pb-Thisotope and age data, monazite U-Pb-Th isotope, trace element and age data, carbon and sulfur stablei

This data release presents results of chemical analyses of groundwater sampled during summer and autumn of 2019 and spring of 2020 from 23 wells in the Great Miami buried-valley aquifer (GM-BVA) of southwestern Ohio. Groundwater and quality-control samples were analyzed to determine concentrations of selected per- and polyfluoroalkyl substances (PFAS). Groundwater and related quality-control sampl

Bathymetry and acoustic-backscatter data were collected during a January 2022 SWATHPlus survey of the Santa Cruz harbor, California (field activity number 2022-609-FA). The data are provided as 1-meter resolution GeoTIFF files.

This database contains demographic and movement variables for 158 adult Agassiz's desert tortoises (Gopherus agassizii) translocated from the National Training Center (NTC), Fort Irwin, in the central Mojave Desert, California, in spring of 2008 and monitored through fall of 2018. The tortoises, fitted with radio transmitters, were translocated to plots south of Fort Irwin and followed monthly unt

WildCast (WILDlife Potential Habitat ForeCASTing Project) is a completed project led by USGS, in collaboration with the National Park Service, the U.S. Fish and Wildlife Service, and the U.S. Forest Service. This aerial photographic transect project of northwest Alaska, acquired photographs, videos, and associated data, during July 16, 17, and 18, 2013. The images depict land cover types as a base

This data release contains reflectance measurements for eight samples submitted to the USGS Organic Petrology Laboratory in Reston. Samples include two artificial rock samples made from cement with organic matter added (samples 001-002), a coal and shale sample (samples 003-004, respectively), and hydrous pyrolysis residues for samples 001-004. The hydrous pyrolysis experiments were conducted at 3
