This product consists of one tabular dataset and associated metadata of water quality information related to rivers, streams, and reservoirs in the Upper Mississippi River watershed between 2012 and 2016. This data release is a part of a national assessment of freshwater aquatic carbon fluxes. Data consist of organic and inorganic carbon related species, carbon dioxide and methane gas fluxes calculated from manual chamber measurements, nitrogen species, carbon isotopes, oxygen isotopes, cations, anions, trace metals, and various in situ measurements including: pH, water temperature, air temperature, barometric pressure, dissolved oxygen, turbidity, fluorescent dissolved organic matter, and specific conductance....

These metadata sets present the comprehensive geochemical composition of solid and water samples from the site of a 11.4ML (million liters) wastewater spill discovered in January, 2015. Analyses of a pipeline sample (analyses of select analytes), supplied by the North Dakota Department of Health are also included. The spill was near Blacktail Creek, north of Williston, ND. The leak was from a pipeline located approximately 70m from Blacktail Creek. The creek flows 17km before entering the Little Muddy River, a tributary to the Missouri River. The study included samples collected in waters upstream and downstream from Blacktail Creek in February and June 2015, June 2016, and June 2017. These data sets include field...

This product consists of multiple tabular datasets and associated metadata of water quality information related to rivers, streams, and lakes in the Yukon River watershed between 2014 and 2018. This data release is apart of the National Aeronautics and Space Administration (NASA) funded Arctic-Boreal Vulnerability Experiment (ABoVE) and is an assessment of water quality and greenhouse gas fluxes within the interior of Alaska. Sampling frequency varied across locations, with some sites sampled twice a year or more. Data consist of: organic and inorganic carbon related species, carbon dioxide and methane gas fluxes calculated from manual chamber measurements, nitrogen species, carbon isotopes, oxygen and deuterium...

This data release provides estimates of monthly wet atmospheric deposition of total inorganic nitrogen (TIN)--the summation of nitrate (NO3) and ammonium (NH4) ions--for the conterminous United States from 1999 through 2020 in units of kilograms nitrogen per square kilometer per month with spatial reference ESPG 4326. The spatial resolution of the gridded data provided in this release is approximately 5 km. The source data used to provide wet deposition estimates include monthly atmospheric concentration data interpolated between National Atmospheric Deposition Program (NADP, 2022) observation stations and monthly precipitation estimates from the National Oceanic and Atmospheric Administration's ClimGrid data (NOAA,...

This data release provides quantitative whole rock geochemical results from The Geysers vapor-dominated geothermal field in California. The concentrations of major elements are reported in oxide weight percent by wavelength dispersive x-ray fluorescence (WDXRF), the concentrations for sixty elements are reported in elemental weight percent (pct) or parts per million (ppm) from inductively coupled plasma-optical emission spectrometry-mass spectrometry ICP-OES-MS analysis, mercury is reported in ppm by cold vapor atomic absorption spectrometry (CVAAS), and ammonium in ppm from automated colorimetry analysis. The analyses show significant enrichment of volatile elements and elements such as sulfur, boron, arsenic,...

Two sets of PHREEQC input and output files are provided that illustrate the distribution of aqueous ammonium and ammonia as a function of physical (temperature) and chemical (pH and solution composition) conditions. One set of simulations calculates the distribution of aqueous ammonia and aqueous ammonium over a range of temperatures and pH values in different solution compositions. The other set of simulations illustrates how aqueous ammonia concentrations in a water body change over time owing to changes in pH and temperature, how ammonia concentrations potentially toxic to salmonids (trout and salmon) can occur owing to changes in pH and temperature, and how these changes in ammonia concentration can be calculated...

This data product contains soil chemistry data from 4 locations. Two of the locations were located in the Neversink River watershed near Claryville, NY (01435000) in the Catskill Mountains of New York (Fall Brook and Winnisook Creek), 1 of the locations was the Young Woman’s Creek watershed near Renovo, PA (01545600) and the last site was the Wild River watershed at Gilead, Maine (01054200). Soil chemistry was collected at 2 times at each location: in 2001 and 2011 in Fall Brook, Young Woman’s Creek and Wild River and in 1993 and 2012 in Winnisook. This data product also contains water-quality data from 5 water-quality stations: West Branch Neversink River at Winnisook Lake [01434021], East Branch Neversink River...
