Nutrients and Major-Ions Measured in Water-Quality Samples Collected from Four North Texas Reservoirs (ver. 3.0, September 2021)

In cooperation with Dallas Water Utilities (DWU), the U.S. Geological Survey (USGS) measures nutrient and major-ion concentrations in selected reservoirs in north Texas. This data release documents water-quality data obtained from Ray Hubbard Lake, Grapevine Lake, Ray Roberts Lake, and Lake Lewisville during water years 2016–20. In addition to nutrient and major-ion concentrations, water-quality field properties and other selected constituents measured in the water-quality samples collected from these reservoirs are documented.
The study began in water year 2016 (WY16) with monthly sampling of Ray Hubbard Lake. A water year is defined as the 12-month period from October 1 through September 30 and is designated by the calendar year in which it ends. During this first year, water-quality samples were analyzed for nutrients only (nitrogen, phosphorous, and multiple species of each nutrient). In water year 2017 (WY17), the study design changed to quarterly sampling, expanded to include Grapevine Lake, and added the analysis of major ions (Calcium, Chloride, Fluoride, Magnesium, Potassium, Silica, Sodium, and Sulfate). In water year 2018 (WY18) to present, the study design further expanded to include quarterly sampling of Ray Roberts Lake and Lake Lewisville. 
For this study, each reservoir currently (2021) has eight sampling sites. Water years 2018, 2019, and 2020 also include water-quality data collected for the USGS Zebra Mussel Monitoring Program for Texas for all four reservoirs. Water-quality samples are collected at a minimum of five equidistant depths, including top and bottom depths, at each site. Samples are analyzed for nutrients, major ions, and bromide by the USGS National Water Quality Laboratory (NWQL) in Denver, Colo. Water-quality field properties (dissolved oxygen, pH, specific conductance, temperature, and Secchi depth) are also measured at each sampling site.
This dataset includes all 4,756 samples from the original data release for the previous water years, plus 1,933 additional samples collected during the 2020 water year. NOTE: While the previous versions are available from the author, all the records from the previous versions can be found in version 3.0.

Structural geologic orientation data for primarily Proterozoic aged rocks, eastern-central Rocky Mountain Front Range, Colorado

This data release consists of point data digitized from structural geologic orientation symbols consisting of mostly foliations and lineations. The data comes from primarily Proterozoic aged rocks in the eastern-central Rocky Mountain Front Range of Colorado. Compilation of the data is from twenty-three geologic maps published by the U.S. Geological Survey and the Colorado Geological Survey between 1964 and 2009, primarily using 7.5-minute, 1:24,000 scale quadrangles. Structural geologic orientation data of planar features (e.g., foliations) and linear features (e.g., fold axes), both with associated attribute values of strike and trend, dip and plunge, location, elevation, and geologic unit were captured for more than 25,000 features in the database. The orientation data captured provides valuable information about the distribution and geometric characteristics of deformation in the area. The data can be used to understand tectonic and geologic framework, the types and influence of basement rock fabrics on subsequent geologic events, and interpret elements of processes associated with the evolution of the upper crust, controls on mineralization, and other Earth resources, such as groundwater. Digitizing this information allows the data to be more readily accessible and thus utilized to perform a variety of geologic, structural geologic, geophysical, and geospatial analyses to create derivative maps to aid in a better understanding of the local and regional geology.

Hawaiian Islands Ceratocystis rapid ohia death spatial analysis 2019

Hawaiʹi’s most widespread native tree, ʹōhiʹa lehua (Metrosideros polymorpha), has been dying across large areas of Hawaiʹi Island mainly due to two fungal pathogens (Ceratocystis lukuohia and Ceratocystis huliohia) that cause a disease collectively known as Rapid ʹŌhiʹa Death (ROD). Here we examine patterns of positive detections of C. lukuohia as it has been linked to the larger mortality events across Hawaiʹi Island. Our analysis compares the environmental range of C. lukuohia and its spread over time through the known climatic range and distribution of ʹōhiʹa.
This data release consists of two rasters, one containing the projected suitability for C.lukuohia and another consisting of modeled presence/absence across the main Hawaiian Islands under current climatic conditions. This distribution model for C. lukuohia was generated using maxent using methods described in Fortini et. al 2019 (Forest Ecology and Management).

Kootenai River Braided Reach Cross-Section Bathymetry Surveys near Bonners Ferry, ID, 2009-2022

In 2009, the Kootenai Tribe of Idaho released and implemented the Kootenai River Habitat Restoration Master Plan. This plan aimed to restore, enhance, and maintain the Kootenai River habitat and landscape to support and sustain habitat conditions for aquatic species and animal populations. In support of these restoration efforts, the U.S. Geological Survey, in cooperation with the Kootenai Tribe of Idaho, conducted high-resolution multibeam echosounder bathymetric surveys as a baseline bathymetric monitoring survey on the Kootenai River near Bonners Ferry, Idaho. Three channel patterns or reaches exist in the study area: braided, meander, and a transitional zone connecting the braided and meander reaches. Bathymetric data were collected to: (1) survey unmapped portions of the Kootenai River; (2) re-survey portions of the Kootenai River to quantify changes in the channel; and (3) monitor aggradation and degradation of the channel bed at specific cross-sections within the braided reach and transitional zone. The bathymetric data will be used to update and verify flow models, calibrate and verify sediment transport modeling efforts, and aid in the biological assessment in support of the Kootenai River Habitat Restoration Master Plan. The data for each study reach were produced in LAZ format supported by most geospatial software.

East Sabine Lake Hydrologic Restoration (CS-32): 2015 land-water classification

The Louisiana State Legislature created Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the East Sabine Lake Hydrologic Restoration (CS-32) project for 2015. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a land-water classification is performed on specific CWPPRA sites to help assess landscape changes.

Horizontal-to-Vertical Spectral Ratio (HVSR) Seismic Surveys in Fredericktown, Missouri, June 2018

In June 2018, U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected geophysical measurements to help evaluate the suitability of a proposed landfill site for disposing mine-waste materials in Fredericktown, MO. A total of 35 horizontal-to-vertical spectral ratio (HVSR) passive seismic measurements were collected at the site. The HVSR technique uses a three-component seismometer to measure the vertical and horizontal components of ambient seismic noise. Seismic noise in the range of approximately 0.1 to 1 Hertz (Hz) is caused by ocean waves, large regional storms, and tectonic sources. A resonance frequency (f0) is induced in the unconsolidated sediments when there is a substantial contrast (greater than 2 to 1 ratio) in shear-wave acoustic impedance between the overburden and the bedrock.
The HVSR data were interpreted to determine the f0 from analysis of the spectral ratio of the horizontal and vertical components of the seismic data. The thickness of the overburden can be related to f0. In general, lower f0 relates to thicker sediments, and higher f0 relates to relatively thinner overburden. At the Fredericktown, MO, site the resonance frequency was related to the depth of the overburden using an average shear-wave velocity that was measured at the site using active seismic source measurements. About two thirds of the HVSR surveys exhibited low to zero amplitude peaks, which is consistent with either a low amplitude acoustic impedance, an overburden layer, or a combination of both that is too thin to measure. The median value of the depth to bedrock for the 10 reliable measurements was 1.6 meters.

Nearshore bathymetry of the Columbia River littoral cell, Washington and Oregon, 2016

This portion of the USGS data release presents bathymetry data collected during surveys performed in the Columbia River littoral cell, Washington and Oregon in 2016 (USGS Field Activity Number 2016-663-FA). Bathymetry data were collected using four personal watercraft (PWCs) equipped with single-beam sonar systems and global navigation satellite system (GNSS) receivers. The sonar systems consisted of an Odom Echotrac CV-100 single-beam echosounder and 200 kHz transducer with a 9 degree beam angle. Raw acoustic backscatter returns were digitized by the echosounder with a vertical resolution of 1.25 cm. Depths from the echosounders were computed using sound velocity profiles measured using a YSI CastAway CTD during the survey. Positioning of the survey vessels was determined at  5 to 10 Hz using Trimble R7 GNSS receivers. Output from the GNSS receivers and sonar systems were combined in real time on the PWC by a computer running HYPACK hydrographic survey software. Navigation information was displayed on a video monitor, allowing PWC operators to navigate along survey lines at speeds of 2 to 3 m/s. Survey-grade positions of the PWCs were achieved with a single-base station and differential post-processing. Positioning data from the GNSS receivers were post-processed using Waypoint Grafnav to apply differential corrections from a GNSS base station with known horizontal and vertical coordinates relative to the North American Datum of 1983. Orthometric elevations relative to the NAVD88 vertical datum were computed using National Geodetic Survey Geoid12a offsets. Bathymetric data were merged with post-processed positioning data and spurious soundings were removed using a custom Graphical User Interface (GUI) programmed with the computer program MATLAB. The average estimated vertical uncertainty of the bathymetric measurements is 10 cm. The final point data from the PWCs are provided in a comma-separated text file and are projected in cartesian coordinates using the Washington State Plane South, meters coordinate system.

Horizontal-to-Vertical Spectral Ratio (HVSR) Passive Seismic at the Callahan Mine Superfund Site in Brooksville, Maine: October 2016 to July 2018

The horizontal-to-vertical spectral ratio (HVSR) method is a passive seismic technique that uses a three-component seismometer to measure the vertical and horizontal components of ambient seismic noise. Seismic noise in the range of ~0.1 to 1 Hertz (Hz) is caused by ocean waves, large regional storms, and tectonic sources. A resonance frequency (f0) is induced in the unconsolidated when there is a substantial contrast (greater than 2:1) in shear-wave acoustic impedance between the overburden and the bedrock. The f0 is determined from the analysis of the spectral ratio of the horizontal and vertical components of the seismic data. The thickness of the overburden can be related to the f0.   In general, lower f0 relates to thicker sediments, and higher f0 relates to relatively thinner overburden. 
At the former Callahan MIne site the resonance frequency can be related to the depth of the overburden using an average shear-wave velocity that is measured or estimated from locations where there is a known depth to rock and/or using a direct measurement of the shear-wave velocity.

Local Niche Model

This dataset provides spatial predictions of the pooled-SDM residuals from a multiscale geographically weighted regression model (MGWR) and the resulting local R2 values for individuals in the subregion encompassing the genetic sampling locations used by Edwards et al. (2015). This region offered an opportunity to explore habitat selection across the ecotone between the Mojave and Sonoran deserts and the secondary contact zone between G. agassizii and G. morafkai, and is referred to as the focal study area. The raster layers contained here accompany the manuscript Inman et al. 2019 and were used to identify multivariate clusters and map them back to geographic space.

Sample collection information and microsatellite data for Gunnison sage-grouse pre and post translocation

Maintenance of genetic diversity is important for conserving species, especially those with fragmented habitats and/or ranges. In the absence of natural dispersal, translocation can be used to achieve this goal. However, the long-term impacts from translocation can be expensive and difficult to evaluate. This dataset is used to evaluate genetic change as a result of translocation and represents samples collected before and after translocations were conducted.

Groundwater withdrawal coefficients and subtotals by water-use type, aquifer, and county, 1995–2010

Values represent withdrawal coefficients and subtotals of groundwater withdrawals coming from the surficial aquifer system, intermediate aquifer system, Floridan aquifer system, or other unnamed or unknown aquifers for given years in the period 1995–2010 in the southeastern United States. Withdrawal coefficients represent the proportion of total groundwater withdrawals coming from each aquifer for a given county, year, and national water use code. Coefficients for each county and water-use category were back-calculated from data published in Marella and Berndt, 2005, Water withdrawals and trends from the Floridan aquifer system in the southeastern United States, 1950–2000: U.S. Geological Survey Circular 1278, 20 p. and from unpublished data from the U.S. Geological Survey South Atlantic Water Science Center (Georgia District).
