Head smut infections on cheatgrass cover in the first four years after the 2015 Soda Wildfire Head smut infections on cheatgrass cover in the first four years after the 2015 Soda Wildfire
Data includes head smut infection level (caused by the fungal pathogen, Ustilago bullata) on cheatgrass (Bromus tectorum) and cheatgrass cover for plots measured annually during the first four years after the 2015 Soda wildfire. Additional landscape and weather covariates that are hypothesized to influence infection and host density are included.

Post-fire vegetation cover, plant species diversity, and Ustilago bullata infection rates at Boise River Wildlife Management Area 2018-2019 Post-fire vegetation cover, plant species diversity, and Ustilago bullata infection rates at Boise River Wildlife Management Area 2018-2019
Invasive-plant treatments often target a single or few species, but many landscapes are diversely invaded. Exotic annual grasses (EAGs) increase wildfires and degrade native perennial plant communities in cold-desert rangelands, and herbicides are thus sprayed to inhibit EAG germination and establishment. We asked how EAG-target and nontarget species responded to an herbicide mixture...
Geo-referenced orthophotographs of the Snow River, Alaska, acquired September 1, 2018 Geo-referenced orthophotographs of the Snow River, Alaska, acquired September 1, 2018
This data release consists of orthophotographs of the Snow River in Alaska acquired on September 1, 2018. The orthophotographs were produced from images obtained using a Hasselblad A6D-100C 100 megapixel digital mapping camera deployed within a pod mounted on the landing gear of a Robinson R44 helicopter. Images were acquired as the helicopter transited a series of flight lines designed...
Data used to model and map arsenic concentration exceedances in private wells throughout the conterminous United States for human health studies Data used to model and map arsenic concentration exceedances in private wells throughout the conterminous United States for human health studies
This data release contains data used to develop models and maps that estimate the probabilities of exceeding various thresholds of arsenic concentrations in private domestic wells throughout the conterminous United States. Three boosted regression tree (BRT) models were developed separately to estimate the probability of private well arsenic concentrations exceeding 1, 5, and 10...
Wetland Stream Water Quality Data for West Twin Creek, AK, Allequash Creek, WI, and Big Thompson River, CO, 2010-2020 Wetland Stream Water Quality Data for West Twin Creek, AK, Allequash Creek, WI, and Big Thompson River, CO, 2010-2020
This dataset includes discrete water quality and discharge data for three streams that flow through wetlands. There are two measurement and sampling locations on each stream: one immediately upstream from the wetland and one immediately downstream from the wetland. Measurements and sample collection occurred in 2010 and 2011 at West Twin Creek, AK; in 2019 and 2020 at Allequash Creek, WI...
Discharge measurements at U.S. Geological Survey streamgage 05536890 Chicago Sanitary and Ship Canal near Lemont, Illinois, 2005-2013 Discharge measurements at U.S. Geological Survey streamgage 05536890 Chicago Sanitary and Ship Canal near Lemont, Illinois, 2005-2013
Discharge measurements made at U.S. Geological Survey Chicago Sanitary and Ship Canal near Lemont, Illinois, streamgage (05536890) between 2005 and 2013 were reviewed and manually processed using QRev v3.12. Discharge was measured using Acoustic Doppler Current Profilers (ADCPs) deployed from a moving boat according to the procedures described in Mueller and others (2013). QRev generates...
Tungsten skarn mineral resource assessment of the Great Basin region of western Nevada and eastern California - Geodatabase Tungsten skarn mineral resource assessment of the Great Basin region of western Nevada and eastern California - Geodatabase
A mineral resource assessment for tungsten, a critical mineral commodity (see 'Related External Resources' section below) for the United States, was carried out by the U.S. Geological Survey (USGS) for a portion of the Great Basin region, in western Nevada and eastern California, between latitudes 36N and 42N and longitudes 116W and 120W. This study (Lederer and others, in review)...
Molecular data to investigate phylogeographic patterns, species boundaries, and demographic history of a North American freshwater mussel species complex (Bivalvia: Unionidae) Molecular data to investigate phylogeographic patterns, species boundaries, and demographic history of a North American freshwater mussel species complex (Bivalvia: Unionidae)
Here we provide public access to three DNA sequence alignments (COI, ND1, ITS1) and details on all specimens utilized in Keogh et al. (in review).
Interpolated groundwater-level surface, spring 2017, Bazile Groundwater Management Area, northeastern Nebraska Interpolated groundwater-level surface, spring 2017, Bazile Groundwater Management Area, northeastern Nebraska
This data set is a raster that represents the groundwater-level surface within the Bazile Groundwater Management Area (BGMA) in spring of 2017. This raster was created for use within the Geoscene3D program which combines airborne electromagnetic geophysical data along with supporting information for visualization and geological modeling. A water-level surface was created as input to a...
Batteries Included Fortran Library (BiF-lib), version 1.0.0 Batteries Included Fortran Library (BiF-lib), version 1.0.0
Standard Fortran provides limited data type, function, and subroutine support leaving the developer to write custom code for every project. This has lead to every developer having their own internal, homemade, Fortran library for doing common operations. In recognition of this, most newer programming languages incorporate a large set of standard data types and functions that the...

Python package to assist with stream network summarization. This package is intended to support efforts for any stream network having general topology (i.e. to/from nodes). Specifically this package was built to support fisheries based analyses using multiple versions of the National Hydrography Database Plus (NHDPlus) representing streams within the United States along with HydroBasins...
