Geospatial data for Gumboot Lake extents from the report Effects of ground-water development on the water regimen of Paradise Valley, Humboldt County, Nevada, 1949-1968 and Hydrologic Reconnaissance of the Tributary Areas Geospatial data for Gumboot Lake extents from the report Effects of ground-water development on the water regimen of Paradise Valley, Humboldt County, Nevada, 1949-1968 and Hydrologic Reconnaissance of the Tributary Areas
This USGS data release consists of polygons representing Gumboot Lake extents from the report Effects of ground-water development on the water regimen of Paradise Valley, Humboldt County, Nevada, 1949-1968 and Hydrologic Reconnaissance of the Tributary Areas (Nevada Department of Conservation and Natural Resources Water Resources Bulletin 39). There are two datasets containing four...
Chorus frog density and population growth, Cameron Pass, Colorado, 1986-2020 Chorus frog density and population growth, Cameron Pass, Colorado, 1986-2020
We investigated population dynamics in chorus frogs (Pseudacris maculata) relative to extrinsic (air temperatures and snowpack) and intrinsic (density dependence) characteristics at 2 sites in Colorado, USA. We used capture-mark-recapture (cmr) data (i.e., 1 or 0, provided here) and a Bayesian model framework to assess our a priori hypotheses about interactions among covariates and...
Waterborne Gradient Self-potential, Temperature, and Conductivity Logging of Lake Travis, Texas, near the Bee Creek Fault, March-April 2020 Waterborne Gradient Self-potential, Temperature, and Conductivity Logging of Lake Travis, Texas, near the Bee Creek Fault, March-April 2020
This data release provides gradient self-potential (SP), conductivity, and temperature measurements made during an investigation of surface-water and groundwater exchange in Lake Travis near Austin, Texas, where the Colorado River is incised into two zones of the Cretaceous-age Trinity aquifer (the lower-zone, and several hydrostratigraphic units of the middle zone). The voltage...
Input and results from a boosted regression tree (BRT) model relating base flow nitrate concentrations in the Chesapeake Bay watershed to catchment characteristics (1970-2013) Input and results from a boosted regression tree (BRT) model relating base flow nitrate concentrations in the Chesapeake Bay watershed to catchment characteristics (1970-2013)
This data release contains a boosted regression tree (BRT) model (written in the R programming language), and the input and output data from that model that were used to relate base flow nitrate concentrations in the Chesapeake Bay watershed to catchment characteristics. The input data consists of two types of information: 1) surface water nitrate concentrations collected by the USGS and
Sea star wasting disease pathology Sea star wasting disease pathology
Sea star wasting disease (SSWD) is a suite of poorly described non-specific clinical signs including abnormal posture, epidermal ulceration, and limb autotomy (sloughing) causing mortalities of over 20 species of sea stars and subsequent ecological shifts throughout the northeastern Pacific. While SSWD is widely assumed to be infectious with environmental conditions facilitating disease
Morphometric measurements of Cisco (Coregonus artedi) from Lake Ontario 2018 Morphometric measurements of Cisco (Coregonus artedi) from Lake Ontario 2018
These data contain morphometric measurements collected on the left side of Cisco (Coregonus artedi) collected from Lake Ontario in 2018. Measurements were obtained by two methods, first by direct measurements made on the thawed specimens using a hand caliper by one person, then using a digital image technique. The digital image measurements were completed by two different measurers to...
