Cryptosporidium and Giardia Occurrence Data in Wildlife from Arctic Alaska, 2012-2017 Cryptosporidium and Giardia Occurrence Data in Wildlife from Arctic Alaska, 2012-2017
This dataset consists of one table with sample collection locations and results of screening resident wildlife for Cryptosporidium and Giardia in the Alaskan Arctic, 2012-2017. We analyzed feces collected from polar bear, Pacific walrus, Arctic fox, and caribou with MERIFLUOR direct immunofluorescence assay to determine the presence of Cryptosporidium oocysts and Giardia cysts.
San Francisco Gartersnake Fecundity Data from San Mateo County, California Collected from 2019-2022 San Francisco Gartersnake Fecundity Data from San Mateo County, California Collected from 2019-2022
Adult female San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) were captured and examined using an ultrasound device to determine if they were gravid and count the number of embryos in those that were. Morphological data including length and mass were collected for each snake, along with the date of capture and a study site identifier. These data support the following...
Code to fit Integral Projection Models and simulate population reintroductions for San Francisco Gartersnakes, Thamnophis sirtalis tetrataenia Code to fit Integral Projection Models and simulate population reintroductions for San Francisco Gartersnakes, Thamnophis sirtalis tetrataenia
This repository contains code to fit Integral Projection Models and simulate population reintroductions for San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) This repository specifically contains code to reproduce analyses in: Rose, J.P., Kim, R., Schoenig, E.J., Lien, P.C., and Halstead, B.J. in-review. Comparing reintroduction strategies for the endangered San Francisco...
Water Surface Velocities in the Downstream Approach to Peoria Lock, near Peoria, Illinois, During Testing of an Automated Barge Clearing Deterrent, September 15, 2022 Water Surface Velocities in the Downstream Approach to Peoria Lock, near Peoria, Illinois, During Testing of an Automated Barge Clearing Deterrent, September 15, 2022
A variety of new technologies are being evaluated to mitigate the spread of invasive carps from the Illinois River to the Great Lakes. In 2022, the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, and U.S. Geological Survey undertook a field-scale interagency study to determine the efficacy of an Automated Barge Clearing Deterrent (ABCD) in flushing live fish away from...
Surrogate regression model data for estimating nitrate concentrations at six springs in Gooding County, south-central Idaho Surrogate regression model data for estimating nitrate concentrations at six springs in Gooding County, south-central Idaho
Endangered Banbury Springs limpet and threatened Bliss Rapids snail populations in springs along the Snake River in southern Gooding County, south-central Idaho, are declining. To protect these species, the U.S. Fish and Wildlife Service (USFWS) needs to understand what affects the species' habitat such as aquatic vegetation, associated with elevated nitrate concentrations in the springs...
Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2022 Bridge-Site Study Data for Selected Highway Crossings in Mississippi, 2022
The U.S. Geological Survey (USGS) works closely with the Mississippi Department of Transportation (MDOT) to provide information to be used by the MDOT for design of highway-drainage structures. MDOT spends millions of dollars annually for highway construction. Streamflow records, hydrologic analyses of basins, and hydraulic analyses of flooding potential at proposed highway crossings...
Model input and projections of compound floodwater depths for the lower Nooksack River and delta, western Washington State Model input and projections of compound floodwater depths for the lower Nooksack River and delta, western Washington State
Model input and computed flood depths associated with the combined influence of sea level position, tides, storm surge, and streamflow under existing conditions and projected future higher sea level and peak stream runoff are provided for the lower (Reach 1) of the Nooksack River and delta in Whatcom County, western Washington State. The flood-depth projection data are provided in a...
Accumulated wastewater calculations for smallmouth bass sampling sites in the Shenandoah River Watershed, USA Accumulated wastewater calculations for smallmouth bass sampling sites in the Shenandoah River Watershed, USA
This data release presents calculated accumulated wastewater (ACCWW, as a percent of total streamflow) values for 43 National Hydrologic Dataset Version 2.1 (NHDPlus V2.1) stream segments coinciding with long-term smallmouth bass sampling locations (Table 1) in the Shenandoah River Watershed (encompassing parts of Virginia and West Virginia, USA). Values are calculated for quarter-year...
Evaluating a tandem human-machine approach to labelling of wildlife in remote camera monitoring Evaluating a tandem human-machine approach to labelling of wildlife in remote camera monitoring
Remote cameras (“trail cameras”) are a popular tool for non-invasive, continuous wildlife monitoring, and as they become more prevalent in wildlife research, machine learning (ML) is increasingly used to automate or accelerate the labor-intensive process of labelling (i.e., tagging) photos. Human-machine hybrid tagging approaches have been shown to greatly increase tagging efficiency (i...
Airborne magnetic and radiometric survey, Boulder Batholith region, Montana, 2022 Airborne magnetic and radiometric survey, Boulder Batholith region, Montana, 2022
This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and Kennecott Exploration Company. The survey was designed to meet complementary needs related to geologic mapping and...
hydrolink - python package hydrolink - python package
The term hydrolink is being defined as the linkage of spatial data to a stream network. This is similar to the analogy of providing an address on a road network and provides locational context and position within a stream network. Hydrolinking data to a common stream network allows information to be centralized helping support landscape scale analyses and modeling efforts. Versions of...
Data for Estimating McKay's Bunting (Plectrophenax hyperboreus) Population Change on St. Matthew and Hall Islands, Alaska Data for Estimating McKay's Bunting (Plectrophenax hyperboreus) Population Change on St. Matthew and Hall Islands, Alaska
This dataset consists of three tables relating to (1) detections of adult McKay's Buntings from line transect with distance estimation surveys on St. Matthew and Hall islands in Alaska between May 30 and June 29, 2003 and June 6 and 11, 2018, (2) environmental covariates associated with detections of adult McKay's Buntings in less than or equal to 250-m long contiguous transect segments...
