Chemistry of groundwater, pore water, and surface water near wetland P1 in the Cottonwood Lake Study Area, Sutsman County, ND - August 2013 Chemistry of groundwater, pore water, and surface water near wetland P1 in the Cottonwood Lake Study Area, Sutsman County, ND - August 2013
Groundwater, soil pore water, and surface water were collected in and near wetland P1 in the Cottonwood Lake Study Area, Stutsman County, North Dakota in August 2013. Groundwater was collected from established wells (17, 18, and 22) via peristaltic pump. Surface water was collected from P1 ponded water via grab sample. Soil pore water was collected using drive point samplers and one...
Method development data – Stabilization of volatile silicon species in hydrofluoric acid (HF) digests of biological samples for HF-free silicon analysis by ICP-MS Method development data – Stabilization of volatile silicon species in hydrofluoric acid (HF) digests of biological samples for HF-free silicon analysis by ICP-MS
Experiments were conducted in the U.S. Geological Survey (USGS) Aqueous Trace Element Analysis Laboratory (ATEAL) in Denver, CO to support development and validation of a method for preparing biological materials for silicon analysis by solution phase inductively coupled plasma mass spectrometry (ICP-MS). The objective was to stabilize volatile silicon species resulting from a digestion...

Geospatial database of the geologic map of the Emmons Lake volcanic center, Alaska Geospatial database of the geologic map of the Emmons Lake volcanic center, Alaska
The Emmons Lake volcanic center is a spatially clustered group of stratovolcanoes and calderas on the Alaska Peninsula near Cold Bay, Alaska. The volcanic center is characterized by several ice- and snow-clad stratovolcanoes located within and along the margins of a nested-caldera complex that includes Emmons Lake. A shieldlike ancestral edifice (ancestral Mount Emmons) is truncated by...
Hydrostratigraphic Groupings of the Craton within CONUS-Extents and Outcrops Hydrostratigraphic Groupings of the Craton within CONUS-Extents and Outcrops
The U.S. Geological Survey (USGS) is developing a National Extent Hydrogeologic Framework (NEHF) for the conterminous United States (CONUS). This digital data set is one of several conceptually linked data releases that provide the underlying spatial data that underpin the development of the NEHF. Three of the datasets describe the thickness and spatial extent of lower Paleozoic rocks...
Water-quality results for municipal effluents, surface water, and urban stormwater: Use of constructed wetlands to support indirect potable reuse in Lake Thunderbird, Oklahoma, 2022-2024 Water-quality results for municipal effluents, surface water, and urban stormwater: Use of constructed wetlands to support indirect potable reuse in Lake Thunderbird, Oklahoma, 2022-2024
The water-quality data contained in this data release was collected in support of a project conducted by the U.S. Bureau of Reclamation (BOR), U.S. Geological Survey (USGS), U.S. Environmental Protection Agency (USEPA), University of Oklahoma, and City of Norman. This multiagency study was conducted to provide information on the use of constructed wetlands to support indirect potable...
