Data

Note: this data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P14PJFWS. This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over an area of southeast Illinois, western Kentucky, and southern Indiana. The survey includes airborne geophysical data collected as part of the U.S. Geological Survey (USGS...

Airborne magnetic surveys were conducted in Oklahoma from August 11th, 2017-October 28th, 2017, by Goldak Airborne Surveys. Here we present downloadable flight line data from those surveys in comma-separated values (csv format). Three areas were flown along a draped surface with a nominal survey height above ground of 120 meters. The flight line spacing for these areas was 200 to 400 m...

The data set consists of 2 spreadsheets from Airsoft Electric Gun (AEG) trials on brown treesnakes. AEG snake wound data contains AEG results from guns equipped with 0.39 gram ammunition (plastic pellets ) that were fired at dead and live snakes from distances of 4, 8, and 12 m to measure tissue-penetration depth, and noted if (a) the pellet was lodged inside the peritoneal cavity, (b)...

Point transect distance sampling data were collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers recorded the detection type (heard, seen, or heard then seen) and horizontal distance (exact distance in m) from the station center point to individual birds detected during an...

Geophysical measurements were collected by the U.S. Geological Survey (USGS) at two sites in Interior Alaska in 2019 and 2020 for the purposes of imaging permafrost structure and quantifying variations in subsurface moisture content in relation to thaw features. In September 2019, electrical resistivity tomography (ERT) and downhole nuclear magnetic resonance (NMR) data were used to...

This .zip file contains four products that will allow users to recreate the analyses and spatial data figures used in Sergeant et al. 2020, A classification of streamflow patterns across the coastal Gulf of Alaska: 1) Autoclass input and output files (provided as folders with multiple simple text files), 2) Classification data (.csv file) for individual watersheds, including Fundamental...

This database contains breeding pond use data (i.e., egg mass and larval abundance counts) of three ambystomatid salamander species (Spotted salamander, Jefferson salamander, and marbled salamander) collected from 200 individual aquatic habitats (ponds, wetlands, and impoundments) in the Delaware Water Gap National Recreation. Data were collected between the years 2001 and 2003. The...

This is a strict open source spreadsheet that can be used to estimate the elapsed time from the beginning of pumping for casing storage water to no longer contribute to the pumping well yield. The spreadsheet is used to estimate the early time drawdown data that should not be analyzed for estimation of aquifer hydraulic properties (transmissivity) from a single pumping well aquifer test...

This data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P9P6WI44 The U.S. Geological Survey, in cooperation with Grand Valley Drainage District, Colorado Water Conservation Board, Colorado Department of Public Health and Environment, and Colorado River Water Conservation District, conducted a loading analysis for selected constituents and tributaries...

Freshwater mussels are a species-rich group with biodiversity patterns shaped by life history strategies that include an obligate parasitic larval stage. Anchored hybrid enrichment (AHE) and ancestral character reconstruction (ACR) revealed convergence of life history strategies involving larval morphologies that reduce size to increase fecundity and require growth during encapsulation...

Data is available on https://chohnz.users.earthengine.app/view/wga-product-comparison-means Cheatgrass (Bromus tectorum) and other invasive annual grasses represent one of the single largest threats to the health and resilience of western rangelands. To address this challenge, the Western Governors Association (WGA)-appointed Western Invasive Species Council convened a cheatgrass working...

This dataset contains annual metrics quantifying low streamflows, climate, topography, land cover and geology for 325 USGS GAGES-2 watersheds within the Delaware River Basin boundary or with watershed centroids within a 25-mile buffer of the Delaware River Basin boundary.
