NHM input and output

This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all U.S. Geological Survey (USGS) Watershed Boundary Dataset of Subwatersheds (Hydrologic Unit Code 12 [HUC12]) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic Model (NHM; Regan and others, 2019) to estimate consumptive use and effective precipitation on irrigated lands. Irrigated lands for the CONUS were provided by the Landsat-based Irrigation Dataset (LANID; Xie and others, 2019) for each year of the reanalysis period. Consumptive use estimates provided by the NHM were disaggregated to HUC12s using area weighted intersections with HRUs and the relative proportion of irrigated lands in each intersected area.
These datasets are generated during the irrigation reanalysis workflow (irrigation_reanalysis.7zip). The files actet_openet.cbh, potet_openet.cbh, and dyn_ag_frac.param are created in step one of the workflow, which involves converting daily OpenET/SSEBop results into inputs for the NHM. All other files are produced by the NHM and are utilized for calculating irrigation consumptive use and effective precipitation.

Biogeochemical and source characteristics of preferential groundwater discharge in the Farmington River watershed (Connecticut and Massachusetts, 2017 - 2021)

We used spatial data from previously mapped preferential groundwater discharges throughout the Farmington River watershed in Connecticut and Massachusetts (https://doi.org/10.5066/P915E8JY) to guide water sample collection at known locations of groundwater discharging to surface water. In 2017 and 2019 - 2021, samples were collected during general river baseflow conditions (July – November, &lt;30.9 cms mean daily discharge (USGS gage 01189995, statistics 2010-2022) when the riverbank discharge points were exposed. We collected a suite of dissolved constituents and stable isotopes of water directly in the shallow saturated sediments of active points of discharge, and coincident stream chemical samples were also collected adjacent to locations of groundwater discharge. Data collected includes nutrients (NO3, NH4, Cl, SO4, PO4, dissolved organic carbon (DOC), and total nitrogen (TN)), greenhouse gases (CO2, CH4, and N2O), dissolved gases (N2, dissolved oxygen (DO)), conductivity, sediment characteristics, temperature, and spatial information.
This dataset includes 2 main files:
1) Farmington_Chemistry_2017_2021.csv contains attribute information for each biogeochemical constituent collected at preferential groundwater discharges along the Farmington River network. 
2)Farmington_Temporal_Cl_Rn_Iso_2020.csv contain attribute information for source characteristic data (Chloride, Radon, Isotope) collected at locations of repeat sampling at 5 groundwater seep faces along the Farmington River (Alsop and Rainbow Island).

Analysis of mitochondrial DNA sequence data from Myotis lucifugus and Myotis occultus

The validity of Myotis occultus as a species unique from M. lucifugus has been a source of debate. Most recently, many authorities treat M. occultus as a distinct species, at least in part because a previous study showed that M. occultus and M. l. carissima (the subspecies that occurs in closest proximity to M. occultus) form separate monophyletic clades based on sequences of two mitochondrial genes (cytochrome-b [cytb] and cytochrome oxidase subunit II [COII]). We re-evaluated the phylogenetic relationship between M. occultus and M. lucifugus based on mitochondrial sequences using an expanded dataset of cytb and COII sequences that originated from more genetically diverse specimens of M. lucifugus collected across a broader geographic area. Based on a phylogenetic analysis, we found that M. occultus sublineages were embedded within a well-supported clade that included some specimens of M. lucifugus. These results indicate that the previous genetic analysis demonstrating that M. occultus and M. lucifugus form distinct monophyletic groups is unsupported by our larger dataset. Future genetic work involving whole genome sequencing of nuclear DNA will likely be needed to better resolve the true taxonomic relationship between M. occultus and M. lucifugus.

Amphibian encounter data and associated covariate data from the Midwest Region of Amphibian Research and Monitoring Initiative (ARMI) surveys 2002-2012

This data set contains information on detections of  anuran (i.e., frogs and toads) species at six different management areas in the midwestern United States from 2002 to 2012. From 2002 to 2005 anuran communities were surveyed during the day using multiple methods at individual study wetlands—visual encounter surveys, dip net surveys, and calling surveys using multiple observers in most cases. Data are presented from each survey.  From 2008 to 2012 amphibian communities were surveyed through detections of vocalizing anurans recorded by automated recording units. Automated recording units recorded five minutes at the top of every hour for the entire field season (typically April through October). Recorder data are presented for up to 15 confirmed detection dates per site per species. Original raw acoustic recordings used to create this data table are archived at the Upper Midwest Environmental Science Center.

Seepage-run discharge measurements, August 9, 2022, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i

This data release contains a comma-delimited ascii file of 16 discrete discharge measurements made at sites along selected reaches of He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i, on August 9, 2022. These discrete discharge measurements form what is commonly referred to as a "seepage run." The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during fair-weather, low-flow conditions that are generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging flow conditions and external surface inflows (for example, a tributary) or outflows (for example, a diversion) of water to the reach are quantified and accounted for in the computation of net seepage.

SHRIMP U-Pb and LA-ICPMS U-Pb geochronologic data for igneous and metasedimentary rocks in central Idaho mineral province, U.S.A.

These data are for a geochronologic study of emplacement ages for plutons of the Cretaceous Idaho batholith and detrital zircon ages for metasedimentary rocks, west-central Idaho. Zircon from six samples of discrete plutons across a regional transect were dated by sensitive high resolution ion microprobe (SHRIMP). SHRIMP U-Pb ages of igneous rocks connect the igneous activity to structural history, crustal depths, and origins of epigenetic gold-silver-antimony-tungsten±mercury mineral deposits. Zircon from four samples of metasedimentary rocks in the southern part of the central Idaho mineral province were dated - three by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) methods and one by SHRIMP methods - to provide maximum depositional ages and details about original sedimentary provenances. These SHRIMP and LA-ICPMS U-Pb data are shared to meet open data requirements.

Global Islands

A new 30-m spatial resolution global shoreline vector (GSV) was developed from annual composites of 2014 Landsat satellite imagery. The semi-automated classification of the imagery was accomplished by manual selection of training points representing water and non-water classes along the entire global coastline. Polygon topology was applied to the GSV, and the resulting polygons were mapped into four size classes of islands: Continental Mainlands, Big Islands (greater than 1 km2), Small Islands (less than or equal to 1 km2 and greater than or equal to 0.0036 km2), and Very Small Islands (less than 0.0036 km2).

Greater sage-grouse network-prioritized functional connectivity cumulative current map (raster)

Conserving genetic connectivity is fundamental to species persistence, yet rarely is made actionable into spatial planning for imperiled species. Climate change and habitat degradation have added urgency to embrace connectivity into networks of protected areas. Our two-step process integrates a network model with a functional connectivity model, to identify population centers important to maintaining genetic connectivity then to delineate those pathways most likely to facilitate connectivity thereamong for the greater sage-grouse (Centrocercus urophasianus); a species of conservation concern ranging across eleven western U.S. states and into two Canadian provinces. This replicable process yielded spatial action maps, able to be prioritized by importance to maintaining range-wide genetic connectivity. We used these maps to investigate the efficacy of 3.2 million-ha designated as Priority Areas for Conservation (PACs) to encompass functional connectivity. We discovered that PACs encompassed 41.1% of cumulative functional connectivity–twice the amount of connectivity as random–and disproportionately encompassed the highest-connectivity landscapes. Comparing spatial action maps to impedances to connectivity such as cultivation and woodland expansion allows both planning for future management and tracking outcomes from past efforts. Included here is a raster map of greater sage-grouse network prioritized functional connectivity cumulative current.

Federal Stakeholder 2022 Online Survey Results for the Re-Prioritization of the USGS Federal Priority Streamgage Network

This data release has the results of 333 online survey respondents representing 17 federal agencies and 7 Executive Branch departments from March 14 through April 14, 2022 regarding The Federal Priority Streamgage (FPS) network of the U.S. Geological Survey (USGS). The FPS network was created in 1999 as the National Streamflow Information Program and receives congressionally appropriated funding to support the operation of a federally funded “backbone” network of streamflow gages across the United States that are designated to meet the “federal needs” or priorities of the country. Anticipating the evolution of federal stakeholder water-data needs, and advances in monitoring and communication technologies, the USGS launched a re-evaluation of the fundamental priorities for the FPS network in October 2020. In March 2022, the FPS Re-Prioritization Project used an online survey to solicit feedback from stakeholders who benefit from the FPS network so it can better serve their needs in the next decade.

Floodplain soil carbon and nutrient retention along a chronosequence of urban stream restorations in Northern Virginia (2022)

Floodplain surficial soil samples (10 cm depth) were collected from 12 streams in the urbanized Piedmont region of northern Virginia, representing a chronosequence of time (1-10 yrs) since stream restoration. In addition, 3 unrestored urban streams and 3 low impervious surface cover reference streams were measured. The samples were analyzed for total carbon (TC), total nitrogen (TN) and total phosphorus (TP) storage, whereas carbon mineralization potential and equilibrium phosphorus concentration (EPC0) were measured as metrics of nutrient and carbon loss. Samples also were analyzed for soil moisture, pH, particle size, organic matter content, and degree of phosphorus saturation.

Continuous groundwater-level monitoring to support the development of a conceptual site model development at the Geneva Industries/Fuhrmann Energy Superfund Site, Houston, Texas, 2022–23

The Geneva Industries/Fuhrmann Energy Superfund Site in southeastern Houston, Texas was historically used as a site for petroleum exploration and petrochemical production and is currently (2023) inactive. Previous remedies to clean up the contaminated site included: excavation and off-site disposal of polychlorinated biphenyl-contaminated soils, capping of residual water on-site with a perimeter slurry wall, the recovery and treatment of trichloroethylene-contaminated groundwater, and institutional controls (Environmental Protection Agency, 2019). A conceptual site model (CSM) does not yet exist and is needed to (1) understand how site conditions have changed since earlier investigations; (2) reevaluate site contaminants of concerns; and (3) determine whether additional remedial actions are needed. A five-phase approach was proposed by the U.S. Geological Survey (USGS) to obtain the data needed to develop a CSM. As the second phase in that approach, the USGS in cooperation with the U.S. Environmental Protection Agency (EPA) collected continuous groundwater-level data from five selected groundwater wells at the Superfund site from June 2022 through January 2023.

Columbia River Basin calcium and pH data accessed on 2022 March 31 for dreissenid mussel risk assessments

Calcium and pH data collected at lake, reservoir, impoundment and stream site types in the Columbia River Basin. These data were downloaded from the National Water Quality Portal on 03/31/2022 and cleaned and filtered. We limited calcium data to just those values that described dissolved calcium and total calcium concentrations. We included total calcium to maximize the amount of data available for this risk assessment; dissolved and total calcium are strongly correlated since dissolved calcium is a constituent part of total calcium. We then cleaned these data by filtering to just those entries associated with water (‘ActivityMediaName’ = Water); dropping rows with ‘NA’ values; removing white spaces; removing duplicated entries; removing negative controls (e.g., field and lab blanks); removing sites associating with mining activity or mining reclamation; standardizing units (mg/L for calcium), and; removing values outside of a sensical range (e.g., 0-14 for pH). These filtering and cleaning steps reduced the number of observations from 932,239 to 567,581.
