Dataset of Helium Concentrations in United States Wells Dataset of Helium Concentrations in United States Wells
This dataset provides national scale location information for known, publicly available, data on helium gas concentrations, reported in mol%. The dataset was created as part of the effort by the United States Geological Survey (USGS) to conduct an assessment of helium resources in accordance with the Helium Stewardship Act of 2013, Public Law 113-40. The data were collected from the USGS...
Dataset: Acute oral toxicity and tissue residues of saxitoxin in the mallard (Anas platyrhynchos) Dataset: Acute oral toxicity and tissue residues of saxitoxin in the mallard (Anas platyrhynchos)
This data set is composed of data collected from an experimental study inoculating mallard ducks (Anas platyrhynchos) with Saxitoxin and associated control ducks. Data includes the specific of inoculation, observational behavioral data, daily weights, dosing, results of inoculation, testing of samples collected throughout the study, and necropsy results.
Datasets for assessing the impact of drought on arsenic exposure from private domestic wells in the conterminous United States Datasets for assessing the impact of drought on arsenic exposure from private domestic wells in the conterminous United States
Documented in this data release are data used to model and map the probability of arsenic being greater than 10 micrograms per liter in private domestic wells throughout the conterminous United States during drought conditions (Lombard and others, 2020). The model used to predict the probability of arsenic exceeding 10 micrograms per liter in private domestic wells was previously...
Datasets for estimating invertebrate response to changes in total nitrogen, total phosphorus, and specific conductance at sites where invertebrate data are unavailable Datasets for estimating invertebrate response to changes in total nitrogen, total phosphorus, and specific conductance at sites where invertebrate data are unavailable
These data were used to describe a possible approach to estimate changes in invertebrate taxa richness at sites across the United States with known water-quality trends but no invertebrate data. This data release consists of invertebrate, water-quality, and covariate data from 1,322 sites and water-quality, covariate, and trend result data from an additional 259 sites with reported water...
Datasets from the focus group series of stakeholder engagement efforts to inform integrated water availability assessment data delivery Datasets from the focus group series of stakeholder engagement efforts to inform integrated water availability assessment data delivery
The U. S. Geological Survey- Water Resources Mission Area is currently developing Integrated Water Availability Assessments (IWAAs) - multi-extent (regional and national), stakeholder driven, near real-time water availability census and prediction for human and ecological uses. To provide appropriate user accessibility to data delivery systems developed for IWAAs, a user-centered design...
Datasets of the hydrogeologic framework of the Red River alluvial aquifer and Carrizo-Wilcox aquifer in northwestern Louisiana Datasets of the hydrogeologic framework of the Red River alluvial aquifer and Carrizo-Wilcox aquifer in northwestern Louisiana
Datasets include hydrogeologic cross section wells within the Red River alluvial aquifer surficial extent, Red River alluvial aquifer base contours and wells, isopach map showing combined thickness of the Red River alluvial aquifer sand and gravel units, wells used to construct the isopach map of the Red River alluvial aquifer, wells used to construct 25-foot contours showing altitude of...
Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020 Datasets used to map the potentiometric surface, Mississippi River Valley alluvial aquifer, spring 2020
A potentiometric-surface map for spring 2020 was created for the Mississippi River Valley alluvial aquifer (MRVA), which was referenced to the North American Vertical Datum of 1988 (NAVD 88), using most of the available groundwater-altitude data from wells and surface-water-altitude data from streamgages. The location and water-level altitude in feet for these wells and streamgages in...
Date for Methane gas ebullition dynamics from different wetland vegetation communities in Big Cypress National Preserve (Florida) are revealed using a multi-method, multi-scale approach Date for Methane gas ebullition dynamics from different wetland vegetation communities in Big Cypress National Preserve (Florida) are revealed using a multi-method, multi-scale approach
Methane emissions from peat soils are highly variable both in space and time and are influenced by changes in certain biogeochemical controls (i.e. organic matter availability; redox potential) and/or other environmental factors (i.e. soil temperature; water level). Consequently, hot spots (areas with disproportionally high emissions) in wetlands may develop where biogeochemical and...
Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2015 Debris-flow and Flood Video Files, Chalk Cliffs, Colorado, USA, 2015
Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km2 study area. These stations are equipped with rain gauges, laser distance meters, and data loggers to record rainfall and stage...

Debris-flow video files, Chalk Cliffs, Colorado, USA, 2017 Debris-flow video files, Chalk Cliffs, Colorado, USA, 2017
Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km^2 study area. This data release includes videos of debris-flows and floods captured by high-definition cameras placed at four...
December 2018 National Wetlands Inventory Mississippi Barrier Islands habitat classification: (Cat Island, Ship Island, Petit Bois Island and Horn Island) December 2018 National Wetlands Inventory Mississippi Barrier Islands habitat classification: (Cat Island, Ship Island, Petit Bois Island and Horn Island)
The Mississippi Coastal Improvements Program (MsCIP) has developed a Comprehensive Barrier Island Restoration Plan containing options to ensure the integrity of the Mississippi barrier islands through restoration efforts. Any restoration activities implemented must have minimal adverse impacts to critical habitat for various marine, terrestrial and avian resources. Documenting the...
