Dissolved oxygen, temperature, and light measured along the water-depth profile of wetlands in North Dakota, USA, 2019 Dissolved oxygen, temperature, and light measured along the water-depth profile of wetlands in North Dakota, USA, 2019
This data release presents data that were collected as part of a larger effort to assess factors that regulate ecosystem metabolism in small ponds. This work was part of an international collaborative effort with the Global Lake Ecological Observatory Network (GLEON). From May to October 2019, dissolved oxygen, temperature, and light were measured throughout the water-depth profile of...

This data release presents data that were collected as part of a larger effort (Global Lake Ecological Observatory Network [GLEON] IceBlitz) to enhance understanding of the spatial and temporal variation in global lake ice properties. During January and February of 2021 ice cores were extracted from Hobart Lake, North Dakota, USA and characterized following standard procedures...
Carbon dioxide flux, vegetation, and soils data from artificial ponds in North Dakota, USA, 2021 Carbon dioxide flux, vegetation, and soils data from artificial ponds in North Dakota, USA, 2021
This data release presents data that were collected as part of a larger effort to assess the carbon balance of recently exposed (i.e., no vegetation cover) wetland sediments. This work was part of an international collaborative effort associated with the Dryflux II project. During June and July 2021, data were collected from three artificial ponds located near Jamestown, North Dakota, to...
Hydrologic and Geochemical Data and Models Supporting Integrated Evaluation of the Captain Jack Superfund Site, Boulder County, Colorado Hydrologic and Geochemical Data and Models Supporting Integrated Evaluation of the Captain Jack Superfund Site, Boulder County, Colorado
The Captain Jack Superfund site near Ward, Colorado hosts extensive interconnected underground mine workings, which drain via the Big Five Adit. Drainage from the adit has historically been acidic with elevated concentrations of metals. In 2018 the U.S. Environmental Protection Agency (EPA) utilized a subsurface remediation strategy consisting of the installation of a hydraulic bulkhead...
Concentrations of pesticides in multiple matrices to measure exposure of wild bees visiting pollinator hedgerows in northern California Concentrations of pesticides in multiple matrices to measure exposure of wild bees visiting pollinator hedgerows in northern California
To better understand the exposure of wild bees to pesticides in an agricultural landscape, samples were collected from fields in northern California. Hedgerows are known to provide habitat for wild bees, but these bees may also be exposed to pesticides from nearby agricultural fields. The study included eight hedgerow sites located in an intensively managed agricultural landscape that...
Pesticides and pesticide transformation product data from passive samplers deployed in 15 Great Lakes tributaries, 2016 Pesticides and pesticide transformation product data from passive samplers deployed in 15 Great Lakes tributaries, 2016
This dataset includes pesticides and pesticide transformation products in 15 tributaries of the Great Lakes. Pesticides were monitored using polar organic chemical integrative samplers (POCIS) to estimate concentrations in water following standard protocols (Alvarez, 2010) in June and July 2016. POCIS extracts were analyzed for 225 chemicals (USGS National Water Quality Laboratory...
Concentrations of inorganic, organic, and microbial analytes from a national reconnaissance of wastewater from food, beverage, and feedstock facilities across the United States Concentrations of inorganic, organic, and microbial analytes from a national reconnaissance of wastewater from food, beverage, and feedstock facilities across the United States
This dataset contains results for treated wastewater samples collected at food processing facilities across the United States to characterize the potential contaminant profile of this type of wastewater. The associated report (Hubbard and others, 2021) can be found at https://doi.org/10.1021/acs.est.1c06821. Samples were analyzed by USGS laboratories using 10 target organic (576 unique...
Data acquired in laboratory experiments conducted with the stonefly Zapada sp. and the ephemerellid mayflies Drunella sp. and Ephemerella tibialis to characterize uptake and surface adsorption after short aqueous exposures to uranium, 2017-2019 Data acquired in laboratory experiments conducted with the stonefly Zapada sp. and the ephemerellid mayflies Drunella sp. and Ephemerella tibialis to characterize uptake and surface adsorption after short aqueous exposures to uranium, 2017-2019
Little is known about the underlying mechanisms governing uranium (U) bioaccumulation in aquatic insects, especially the influence of surface adsorption on the measured U concentrations (Henry et al. 2020). U.S. Geological Survey scientists are conducting experiments to parameterize conditional rate constants for aqueous U uptake and to quantify desorption of weakly bound U from insect's
Data on barium, strontium, cobalt, and nickel plumes formed during microbial iron-reduction on sediments and in water from a crude-oil-contaminated aquifer, Bemidji, Minnesota (2009-2019) Data on barium, strontium, cobalt, and nickel plumes formed during microbial iron-reduction on sediments and in water from a crude-oil-contaminated aquifer, Bemidji, Minnesota (2009-2019)
This U.S. Geological Survey (USGS) Data Release provides concentrations from groundwater and soil extracts for iron (Fe), barium (Ba), strontium (Sr), cobalt (Co), and nickel (Ni). Groundwater analyses for pH and alkalinity are also included. Samples were collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site, near Bemidji MN (USA) between 2009-2019. The...
Impacts of extreme environmental disturbances on survival of piping plovers breeding in the Great Plains, and wintering along the Gulf of Mexico and Atlantic Coasts, 2012-2019 Impacts of extreme environmental disturbances on survival of piping plovers breeding in the Great Plains, and wintering along the Gulf of Mexico and Atlantic Coasts, 2012-2019
We present one tabular data file to evaluate piping plover (Charadrius melodus) seasonal (breeding and nonbreeding) adult survival. These data were part of a study to examine adult (n = 3474) survival during 2012-2019 at breeding regions within the Northern Great Plains and nonbreeding regions in the Gulf and southern Atlantic Coasts of North America. This file includes USGS-funded data...
Piping plover hatch-year survival and natal dispersal probabilities in the Northern Great Plains, USA 2014-2019 Piping plover hatch-year survival and natal dispersal probabilities in the Northern Great Plains, USA 2014-2019
We present a tabular data set representing values to estimate apparent hatch-year survival to adulthood and natal dispersal probabilities between two breeding groups of the Northern Great Plains piping plover (Charadrius melodus) used in a multievent capture-mark-resight model from 2014-2019. Focusing on the Northern Missouri River and U.S. Alkali Wetlands breeding groups. In addition...
Stream discharge, sodium, bromide, and specific conductance data for stream and hyporheic zone samples affected by injection of sodium bromide tracer, Leavenworth Creek, Clear Creek County, Colorado, August 2012 Stream discharge, sodium, bromide, and specific conductance data for stream and hyporheic zone samples affected by injection of sodium bromide tracer, Leavenworth Creek, Clear Creek County, Colorado, August 2012
Leavenworth Creek, a tributary of South Clear Creek and Clear Creek near Georgetown, Colorado contains copper, lead, and zinc concentrations that are near to or exceed aquatic life standards. The creek drains the Argentine mining district where mining was active primarily in the early 1900s. In the summer of 2012, the U.S. Geological Survey (USGS) conducted a metal-loading study using...
