Synthesized Domestic Well Database for the Conterminous United States Synthesized Domestic Well Database for the Conterminous United States
Self-supplied domestic water sources play a significant role in the United States' water landscape, serving approximately 13 percent of the nation's population as of 2015 (Dieter and others, 2018). However, these sources present unique challenges for water resource management and research due to the lack of monitoring, withdrawal location, and place-of-use data. To address this data gap...
Greenhouse Gas Fluxes along a Tidal Gradient of Low Salinity Freshwater Forested Wetlands Greenhouse Gas Fluxes along a Tidal Gradient of Low Salinity Freshwater Forested Wetlands
A dynamic closed chamber system was used to measure in situ efflux rates of CO2, CH4, and N2O to the atmosphere from wetland soils along the Mattaponi and Pamunkey rivers. These greenhouse gas (GHG) flux measurements were taken quarterly from December 2015 to September 2017, at replicated hummock and hollow microtopography locations (where present) within each site. CO2 flux was measured...
Mississippi Barrier Islands Habitat Classification, National Wetlands Inventory, December 2017: (Cat Island, Ship Island, Horn Island, and Petit Bois Island) Mississippi Barrier Islands Habitat Classification, National Wetlands Inventory, December 2017: (Cat Island, Ship Island, Horn Island, and Petit Bois Island)
This data set consists of digital data describing wetlands and uplands habitats for the Mississippi Coastal Improvements Program (MsCIP) area, consisting of Cat, Ship, Horn and Petit Bois Islands for the year 2021. Wetlands were classified using the Cowardin et al. (1979) wetlands classification scheme to the level of freshwater and tidal salinity modifiers. For this dataset, upland...

This dataset contains data from a trapping effort targeting Razor-backed Musk Turtles (Sternotherus carinatus) across Louisiana.
Per- and Polyfluoroalkyl Substances (PFAS) and Co-occurring Contaminants in the Fraser River, a Headwater Tributary to the Colorado River - September 2021 to August 2023 Per- and Polyfluoroalkyl Substances (PFAS) and Co-occurring Contaminants in the Fraser River, a Headwater Tributary to the Colorado River - September 2021 to August 2023
The Fraser River, located in the Colorado Rocky Mountains, is a headwater tributary to the Upper Colorado River. This investigation by the U.S. Geological Survey (USGS) Water Mission Area, Water Quality Processes Program Proxies Project was conducted from September 2021 through August 2023 and consisted of eight sampling events incorporating 17 sites (15 stream sites and two wastewater...
Concentrations of Inorganic and Organic Substances in Lake Ontario and Surrounding Tributaries, New York, April to October 2023 Concentrations of Inorganic and Organic Substances in Lake Ontario and Surrounding Tributaries, New York, April to October 2023
This data release contains nutrient, metal, hormone, pharmaceutical, dioxin, and furan concentration data and field readings associated with surface water samples collected from 35 locations along the New York shoreline of Lake Ontario and surrounding tributaries. Samples were collected from April 2023 through October 2023 at nearshore, embayment, and tributary sites from Niagara River...
