Natural Monthly Flow Estimates for the Conterminous United States, 1950-2015

This metadata record describes monthly estimates of natural stream flows for greater than 2.5 million stream reaches, defined by the National Hydrography Dataset (NHD) Version 2.0, in the conterminous United States for the period 1950-2015.  A statistical machine learning technique - random forest modeling - was applied to estimate natural flows using 200 potential predictor variables.  The dataset is organized by level 3 ecoregions, with each ecoregion having its own directory.  Separate .csv files for each stream reach in the NHD network belonging to a given ecoregion are contained within the respective ecoregion directories.  The stream reach .csv files are named as the NHD COMID corresponding to that stream reach.  Methods used to calibrate the random forest models, and references to predictor data sources are detailed in the Journal of the American Water Resources Associate  paper "A database of natural monthly flow estimates from 1950-2015 for the conterminous United States" by Miller and others (2018).  See the discussion paper link in the "Related External Resources" section for access.

Dissolved organic matter data in surface water samples from Minnesota Lakes, 2012 to 2013

The sampling of three hydrologically diverse Minnesota Lakes (Williams Lake, Shingobee Lake, and Lake Manganika) took place during the years of 2012 to 2013. Water samples were collected and filtered in the field using 0.45 micrometer capsule filters (Versapor membrane), silicon tubing, and a peristaltic pump. Water samples were then shipped on ice to the U.S. Geological Survey in Boulder, Colorado and chilled to approximately 4 degrees Celsius until analysis. Dissolved organic matter (DOM) was separated into fractions by an isolation method that passes aqueous sample through Amberlite XAD8 and XAD4 resins using low pressure liquid chromatography. The hydrophobic organic acid (HPOA) fraction is the eluate from the XAD8 fractionation column and the transphilic organic acid (TPIA) fraction is the eluate from the XAD4 fractionation column. Dissolved organic carbon (DOC) was measured on an OI700 Analytical total organic carbon analyzer by wet-oxidation; each sample was measured in replicate and the average was reported. Ultraviolet (UV) absorbance at the wavelength of 254 nm was measured with an Agilent HP8453 UV-Vis spectrophotometer. Specific UV Absorbance (SUVA) at 254 nm is a calculated parameter defined as the UV absorbance at a wavelength of 254 nm in absorbance units per centimeter divided by the DOC concentration in milligrams per liter and then multiplied by 100. SUVA 254 nm is reported in units of liters per milligram carbon per meter and correlates with the percent aromatic carbon of the DOM. Iron(III) absorbs UV light at 254 nm and, if present at appreciable concentration, can influence UV absorbance and calculated SUVA values. Utilizing a Hach spectrophotometer, total iron concentration was measured. The total iron concentrations of filtered whole water samples from each Minnesota Lake site were determined, and were not high enough to significantly influence SUVA 254 nm values. Associated laboratory quality assurance and quality control measures have been taken to produce final data.

Total and aqueous arsenic concentrations, physiochemical characteristics, and ancillary data of groundwater from newly constructed drinking water wells in central, northwest, and northeast Minnesota, 2014 – 2016, version 2.0, July 2018

This data release provides total and aqueous arsenic (As) determinations and associated field readings collected from groundwater sampled from 254 newly constructed private residential wells from 2014-2016. The study focuses on three regions of Minnesota that differ geologically: south-central (herein called central), northwest, and northeast. These study regions were chosen due to their prevalent elevated As concentrations in drinking water. Each of the 254 wells were sampled in three rounds by the Minnesota Department of Health (MDH). The timing of the three sampling rounds was (1) immediately or shortly after well construction (round 1); (2) 3-6 months after initial sample collection (round 2); and (3) 12 months after initial sample collection (round 3). During each round, samples were collected for both total and aqueous As. Physicochemical characteristics, including specific conductance, pH, dissolved oxygen, oxidation reduction potential, and temperature, were also measured to gage the well water stability prior to sample collection. Round 1 sampling was timed to co-occur and mimic well driller regulatory sampling. Drillers collected samples after well development from the drill rig groundwater pump or from the residential plumbing and the MDH sampler replicated the sample location and timing used by the driller. Sampling from the drill rig's groundwater pump occurred after the well was drilled and developed, when the water was visibly clear, with little visible sediment particles. Samples from plumbing were collected after the plumbing was flushed out and physicochemical characteristic readings stabilized. Round 2 and round 3 by MDH staff were collected only from plumbing. Samples collected from plumbing were taken from faucets, hydrants, or pressure tanks prior to filters or treatment systems.

Manatee environmental DNA data, and associated attributes, collected from the United States, Cuba, and Cameroon, from 2013-2015

Environmental DNA (eDNA) detection is a rapidly expanding technique used to non-invasively detect cryptic, low density, or logistically difficult-to-study species, such as imperiled manatees. Genetic material shed into the environment through tissue and body fluids is concentrated from water samples and analyzed for the presence of targeted eDNA. To help delineate manatee habitat ranges, high use areas, and seasonal population changes, a cytochrome-b quantitative PCR and state-of-the-art droplet digital PCR (ddPCR) eDNA assay was developed for the three extant and vulnerable manatee species: both subspecies of the West Indian manatee (Florida and Antillean), the African manatee and Amazonian manatee. Occurrence (ψ) and detection (p) probabilities were estimated to inform management efforts and population monitoring. To validate the assay, water was analyzed from a relatively high-density Florida manatee east coast population and produced an average 31,564 target DNA molecules/liter (ψ=0.84 (0.40-0.99); p=0.99 (0.95-1.00)).  Similar occupancy estimates were produced from investigations of less well-characterized Florida manatee populations in the Florida Panhandle (ψ=0.79 (0.54-0.97)) and Cuba (ψ=0.89 (0.54-1.00)) while occupancy estimates of the African species in Cameroon were lower (ψ=0.49 (0.09-0.95)).  The estimates were higher than those generated using aerial survey data on the west coast of Florida.  Future eDNA studies could assess locations where manatees are difficult to identify visually (e.g., dark or turbid water common in the Amazon River, and Africa), are present in patchy distributions, or where repatriation efforts are proposed (e.g., Brazil, Guadeloupe).  Moreover, this technology could be extended to species on the verge of extinction (e.g., manatees in Jamaica and Haiti, and Asian dugongs), where conventional survey methods are challenging.

Flood Inundation Grids and Shapefiles for the Pawtuxet River in West Warwick, Warwick, and Cranston, Rhode Island

A series of 15 digital flood-inundation shapefiles and grids were developed for a 10.2 mile reach of the Pawtuxet River in West Warwick, Warwick, and Cranston, Rhode Island by the U.S. Geological Survey in cooperation with Rhode Island Emergency Management Agency and U.S. Army Corps of Engineers. The coverage of the maps extends from downstream of Natick Pond Dam near State Route 33/Providence Street bridge in West Warwick, to the river’s mouth at Pawtuxet Cove (Broad Street bridge) on the border between Cranston and Warwick, Rhode Island.    
A hydraulic model was used to compute water surface profiles for 15 flood stages at 1-foot (ft) intervals referenced to the streamgage and ranging from 8.0 feet (ft; 15.2 ft North American Vertical Datum of 1988), which is the National Weather Service Advance Hydrologic Prediction Service’s flood action stage, to 22.0 ft (29.2 ft North American Vertical Datum of 1988), which is the maximum rated stage at the streamgage and exceeds the National Weather Service Advance Hydrologic Prediction Service’s major flood stage of 13.0 ft. The simulated water-surface profiles were combined with a Geographic Information System digital elevation model derived from light detection and ranging (lidar) data with a 1.0-ft vertical accuracy to create flood inundation maps. The flood inundation maps depict estimates of the areal extent and depth of flooding corresponding to selected 15 flood stages at the U.S. Geological Survey Pawtuxet River at Cranston, Rhode Island streamgage (01116500).

Digital elevation model outputs from wetland accreting rate model of ecosystem resilience (WARMER) at ten year intervals from 2010-2110

Digital elevation model outputs from wetland accreting rate model of ecosystem resilience (WARMER) at ten year intervals from 2010-2110. Baseline elevations were collected with RTK GPS units and LiDAR elevations in non-surveyed areas were also corrected using LEAN method. Historical accretion rates were collected at each salt marsh and used to parameterize WARMER, predicting future elevations.

Data release for results of societal exposure to California's volcanic hazards

The U.S. Geological Survey, California Volcano Observatory (CalVO) in collaboration with the State of California Governor’s Office of Emergency Services and the California Geological Survey, are working to understand the State’s exposure to volcanic hazards by integrating volcanic hazard information with geospatial data on at-risk populations, infrastructure, and resources. These data are from the geospatial analysis of the assets against volcano hazard zones (near vent, lava flow, lahar, flood, and ash fall) for California volcanoes ranked as Moderate, High, or Very High Threat in the US Geological Survey's 2005 report entitled “Volcanic Threat and Monitoring Capabilities in the United States” available on-line at http://pubs.usgs.gov/of/2005/1164/. These data, in tabular format, are intended for use in GIS software applications and other standalone spreadsheet applications.
Volcanic threat is defined in the 2005 report as the combination of hazards (the dangerous or destructive natural phenomena produced by a volcano) and exposure (the people, property, and resources at risk from the volcanic phenomena). The U.S. Geological Survey has systematically assessed hazard and exposure factors to calculate an overall threat score for the 169 U.S. volcanoes that are either currently in an eruptive phase, show signs of unrest due to magma at depth, or those young enough to be capable of reawakening (eruptions within the past 10,000 years). Pertinent to this metadata compilation are the volcanic hazard exposure data for Moderate-to-Very High threat volcanoes including Medicine Lake Volcano, Mount Shasta, Lassen Volcanic Center, Long Valley Volcanic Region, Clear Lake Volcanic Field, Ubehebe Craters, and Salton Buttes.

U.S. Geological Survey National Produced Waters Geochemical Database v2.3

During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential sources of drinking or agricultural water. In addition to waters co-produced with hydrocarbons, geothermal development or exploration brings deep formation waters to the surface for possible sampling. This U.S. Geological Survey (USGS) Produced Waters Geochemical Database, which contains geochemical and other information for 114,943 produced water and other deep formation water samples of the United States, is a provisional, updated version of the 2002 USGS Produced Waters Database (Breit and others, 2002). In addition to the major element data presented in the original, the new database contains trace elements, isotopes, and time-series data, as well as nearly 100,000 additional samples that provide greater spatial coverage from both conventional and unconventional reservoir types, including geothermal. The database is a compilation of 40 individual databases, publications, or reports. The database was created in a manner to facilitate addition of new data and correct any compilation errors, and is expected to be updated over time with new data as provided and needed. Table 1, USGSPWDBv2.3 Data Sources.csv, shows the abbreviated ID of each input database (IDDB), the number of samples from each, and its reference. Table 2, USGSPWDBv2.3 Data Dictionary.csv, defines the 190 variables contained in the database and their descriptions. The database variables are organized first with identification and location information, followed by well descriptions, dates, rock properties, physical properties of the water, and then chemistry. The chemistry is organized alphabetically by elemental symbol. Each element is followed by any associated compounds (e.g. H2S is found after S). After Zr, molecules containing carbon, organic 9 compounds and dissolved gases follow. Isotopic data are found at the end of the dataset, just before the culling parameters.

Selected geochemistry and mineralogy of Paleozoic strata in northern and central Appalachian basin, U.S.A., 1994-2012

A U.S. Geological Survey (USGS) provisional geochemical and mineralogical database for hydrocarbon-rich shale in the Appalachian region has been compiled by Catherine Enomoto, Frank Dulong and Robert Milici for online distribution. USGS staff collaborated with geologists in State geological agencies to obtain samples that were analyzed for organic properties, including Rock Eval analyses, total organic carbon (TOC), thermal maturity, and semi-quantitative mineralogy. However, the database also contains previously published data, with appropriate citations included. Previously unpublished data are from samples collected and analyzed between 2007 and 2012 from wells drilled between 1931 and 2009, and from exposures in the northern and central Appalachian basin.
