Multi-element geochemical analyses of selected samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA

This data release provides multi-element data for drill core samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA. Gold, platinum, and palladium data were collected by fire assay; copper and silver were collected by assay; and other elements were collected by inductively coupled plasma-optical emission spectrometry (ICP-OES) or inductively coupled plasma-mass spectrometry (ICP-MS) following a digestion that used hydrochloric, nitric, perchloric and hydrofluoric acids. The Copperwood copper deposit is a sediment-hosted stratiform copper deposit in the Presque Isle Syncline of the upper peninsula of Michigan. The deposit has a 2018 mineral resource estimate of 42.2 million metric tons (Mt) of measured plus indicated mineral resources in the Lower Copper Bearing Sequence at an average grade of 1.60 percent Cu and 3.84 grams per ton (g/t) Ag. The measured plus indicated mineral resource in the Upper Copper Bearing Sequence is estimated to be 7.1 Mt at an average grade of 1.21 percent Cu and 3.26 g/t Ag (Gignac, 2018). The mineral reserves for the Copperwood Project are estimated at 25.4 Mt at an average grade of 1.43 percent Cu and 3.83 g/t Ag (Gignac, 2018). Some sediment hosted deposits elsewhere produce significant amounts of gold, platinum, palladium, and (or) cobalt. However, in the Copperwood samples, these elements have geometric mean concentrations of 0.0022 ppm, 0.0021 ppm, 0.0029 ppm, and 24 ppm, respectively, so they are not enriched. Gallium, which is a critical mineral in the U.S., is enriched in some base metal deposits, but Copperwood samples have a geometric mean gallium concentration of 16 ppm, which is similar to average crustal concentrations. Although the data herein are limited to 34 determinations, they strongly suggest that the Copperwood copper deposit does not contain significant concentrations of byproduct critical minerals.

This data release contains inputs and outputs for hydrologic simulations of the conterminous United States (CONUS) using the National Hydrologic Model (NHM) application of the Precipitation Runoff Modeling System (PRMS) in ASCII and binary format and explanatory graphics in pdf format. These simulations were developed to provide estimates of water availability for historical conditions for the period October 1, 1980 to September 30, 2016 for five different calibration configurations; the first three years of the simulation should be considered the initialization period and should not be used for subsequent analysis. The five versions of model parameters and associated model output included in this data release are described in table 1 and in the Supplemental Information section of this metadata record. Table 2 provides information about the baseline datasets used for model calibration for each of the five parameter configurations. Figure 1 shows a schematic of the multi-step calibration procedure used to develop the model parameters. Table 3 describes the 36 model output variables that are included in the five attached folders. Five .tar folders are named according to the simulation configuration in table 1 and include the 36-model output variable files. Table 4 provides information about the 8,274 streamgage locations that are included in the NHM-PRMS. The NHM-PRMS parameter and control files for each of the five simulations are located on the child pages associated with this data release. The PRMS climate forcing input files for the simulations are in the DAYMET_CBH.zip folder. Summary files by streamgage of measured and simulated streamflow for the byHRU, byHRU_musk, and byHRU_musk_obs simulations are in the Streamgage_location_simulations_5999.zip folder. Any time series data in the model output files prior to the October 1, 1983 start date should be considered part of the model initialization period and should not be used. Please refer to the Supplemental Information element of this metadata record for more information about the model calibration, inputs, outputs, and summaries included in this data release.

Application of the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System (NHM-PRMS), 1950-2010, Maurer Calibration

This data release contains inputs for and outputs from hydrologic simulations for the conterminous United States (CONUS) using the Precipitation Runoff Modeling System (PRMS) version 5.1.0 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). These simulations were developed to provide estimates of the water budget for the period 1950 to 2010. Specific file types include: 1) input atmospheric forcings of minimum air temperature, maximum air temperature, and daily precipitation accumulation derived from a gridded observation-based dataset developed by Maurer and others (2002), 2) input parameter files for static and dynamic land cover conditions, and 3) output files of simulated water budget components for each hydrologic response unit and stream segment. Figure 1 shows the calibration methodology that was used for the model application (see LaFontaine and others, 2019 for additional information). Table 1 lists the streamgages that are included in the model application. Table 2 lists the calibration datasets that were used in addition to USGS measured streamflow. The first three years of the simulations are considered 'model initialization' and should not be included in any subsequent analsysis.

Precipitation and Precipitation Chemistry in Robinson Forest, Breathitt County, Kentucky (1971-2018)

Robinson Forest, in eastern Kentucky, is a research forest owned and operated by the University of Kentucky (UK) since the 1920s. The UK Department of Forestry and Natural Resources began collecting precipitation and precipitation chemistry data in the forest starting with one weather station at the Robinson Forest Camp in 1971, and followed by several additional stations in the mid-1990s. This digital dataset includes information about the weather stations where these data were collected, and how these data were processed. These data include precipitation and precipitation chemistry (chloride, nitrates, sulfates, ammonium, pH, alkalinity, calcium, magnesium, potassium, sodium, conductivity, total organic carbon, and phosphates), and were collected from six stations from 1971-2018. For previous research, we used an average from three of the precipitation gages, creating a composite record with the knowledge that spatial variability is addressed and a continuous record is provided even if individual gages are not functioning.

Flood frequency and source data used in the regional regression analysis of annual peak flows in Connecticut (2020) (ver. 2.0, April 2021)

Current estimates of the magnitude and frequency of floods at gaged and ungaged stream sites are critical for assessing flood risk, delineating flood zones, designing hydraulic structures, and managing flood plains. The Connecticut Department of Transportation collaborated with U.S. Geological Survey (USGS) in a study to improve the flood-frequency estimates in Connecticut and develop regional regression equations for estimating annual exceedance probability discharges at ungaged sites in Connecticut. The results of the study are found in Scientific Investigations Report (add link). This companion data release consists of data compiled and used for the flood-frequency analysis of annual peak flows and development of regional regression equations for Connecticut. The data release is composed of four tables that include: 1) descriptions and locations of streamgages for flood frequency analysis of annual peak flows; 2) updated flood discharges for 152 streamgages for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEP) using annual peak data through water year 2015; 3) representation of peak flow data using perception thresholds and interval data in the flood frequency analysis to describe uncertainty and represent missing and historical records; and 4) basin and climatic characteristics that were included as explanatory variables in the regression equations.

Data for multiple linear regression models for predicting microcystin concentration action-level exceedances in selected lakes in Ohio

Site-specific multiple linear regression models were developed for eight sites in Ohio—six in the Western Lake Erie Basin and two in northeast Ohio on inland reservoirs--to quickly predict action-level exceedances for a cyanotoxin, microcystin, in recreational and drinking waters used by the public.  Real-time models include easily- or continuously-measured factors that do not require that a sample be collected.  Real-time models are presented in two categories: (1) six models with continuous monitor data, and (2) three models with on-site measurements.  Real-time models commonly included variables such as phycocyanin, pH, specific conductance, and streamflow or gage height. Many of the real-time factors were averages over time periods antecedent to the time the microcystin sample was collected, including water-quality data compiled from continuous monitors.  Comprehensive models use a combination of discrete sample-based measurements and real-time factors.  Comprehensive models were useful at some sites with lagged variables (&lt; 2 weeks) for cyanobacterial toxin genes, dissolved nutrients, and (or) N to P ratios.  Comprehensive models are presented in three categories: (1) three models with continuous monitor data and lagged comprehensive variables, (2) five models with no continuous monitor data and lagged comprehensive variables, and (3) one model with continuous monitor data and same-day comprehensive variables.  Funding for this work was provided by the Ohio Water Development Authority and the U.S. Geological Survey Cooperative Water Program.

Discrete water-quality data supporting Herring River restoration project, Cape Cod National Seashore, 1984-2017

Staff from the Cape Cod National Seashore, National Park Service (CACO NPS) began limited water-quality data collection in the Herring River Estuary as early as 1984. In 2006 a monthly sampling program was established for 14 sites to monitor nutrient concentrations, dissolved oxygen, and other constituents. This monitoring program is ongoing and has been supplemented with data from other CACO NPS projects and cooperative monitoring with the U.S. Geological Survey. With the anticipated restoration of the estuary, which has been diked off from the ocean for over 100 years, these data are critical in supporting the characterization of pre-restoration water quality. The data collected in the estuary from 1984-2017 have not been published and disseminated in one place to date. This data release is intended to address this issue and create a framework in which future data can be published. In preparation for publication, the data were compiled from several CACO NPS internal sources and were reviewed using very preliminary quality checks. The related USGS water-quality data are available in the National Water Information System (NWIS).

GPS tracking of Brown Pelican in the South Atlantic Bight during cyclonic activity (2017-2018)

This dataset comprises GPS locations analyzed in Wilkinson et al. (20XX): 14,478 deployed GPS locations, for 32 Eastern brown pelicans tracked during Hurricanes Irma, Florence, and Michael in autumn 2017 and 2018, respectively.
Funding for this study was provided by the U.S. Geological Survey Ecosystem Missions Area, and facilitated by Mona Khalil (USGS). 
Among seabirds, the Eastern brown pelican (Pelecanus occidentalis carolinensis) is a large-bodied coastal species inhabiting nearshore habitats. Breeding on sea islands free of mammalian predators in subtropical and tropical North America, colonies range in size from 10 - 5000 pairs. Egg laying (clutch size of 2-3 typical) occurs primarily in April and May, with each nest producing 1-2 fledglings from July to August. After breeding, adults migrate facultatively, with some individuals remaining near the breeding colony while others disperse much greater distances. The brown pelican is unique in that it captures prey via plunge diving from great heights, where it targets primarily surface-schooling fish. During the post-breeding period in the South Atlantic Bight and elsewhere, adult pelicans are subject to cyclonic activity as hurricanes develop and pass through the region. We deployed 65-g solar GPS Platform Terminal transmitters (GeoTrak, Inc., North Carolina, USA) on adult pelicans from three colonies in coastal South Carolina from 2017-2018. From September - October, transmitters were programmed to record 10 fixes/day (every 90 min from 0700 to 0100 GMT). Transmitters were attached with a backpack harness system composed of Teflon ribbon. Adults were captured at the nest in early-chick rearing or late incubation with a noose pole. Captured pelicans were weighed, measured, banded, and sampled for genetic blood and feathers in addition to tagging.
GPS data were visually assessed and outliers removed manually. Data represents only movements recorded during passages of Hurricanes Irma, Florence, and Michael. Data must be processed before analysis.
