Evapotranspiration Data within Blue Cypress Marsh, Vero Beach, Florida, 2021 Evapotranspiration Data within Blue Cypress Marsh, Vero Beach, Florida, 2021

The dataset includes a table in comma delimited format of daily evapotranspiration (ET) from 1/1/2021 to 12/31/2021 from an ET station within the Blue Cypress Marsh Conservation Area, near Vero Beach, Florida. Evapotranspiration was estimated using eddy-covariance methods and missing sub-daily (30-minute) and daily ET records were gap-filled with a version of the Turc equation (Trajkovic...

Permeameter test data collected in the streambed sediments of the Cedar River near Cedar Rapids, Iowa, 2014 Permeameter test data collected in the streambed sediments of the Cedar River near Cedar Rapids, Iowa, 2014

This data release contains a set of permeameter test data collected in February and March of 2014 on the Cedar River near Cedar Rapids, Iowa. The permeameter tests were performed in proximity to five horizontal collector wells (HCs) 1, 2, 3, 4, and 6, and three vertical wells that are operated by the City of Cedar Rapids. Each dataset represents groundwater levels over time while...

Code to analyze Capture-Mark-Recapture data of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) Code to analyze Capture-Mark-Recapture data of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia)

Code files "growth_analysis.R" -An R script to fit the von Bertalanffy growth model to growth data from San Francisco gartersnakes. The von Bertalanffy growth model is fit using JAGS software (Plummer 2003), and is based on the model presented in Armstrong and Brooks (2013).

Histopathology of tri-colored bats (Perimyotis subflavus) exposed to the fungus Pseudogymnoascus destructans under varying temperature and humidity conditions Histopathology of tri-colored bats (Perimyotis subflavus) exposed to the fungus Pseudogymnoascus destructans under varying temperature and humidity conditions

This work is part of an experimental trial investigating the effects of microclimate conditions of temperature and humidity on a fungal pathogen, Pseudogymnoascus destructans (Pd), that causes white-nose syndrome (WNS) disease in hibernating bats. As part of the trial, tri-colored bats (Perimyotis subflavus) were exposed to Pseudogymnoascus destructans (Pd) and allowed to hibernate in...

Risk assessment of chanchita Cichlasoma dimerus (Heckel, 1840), a newly identified non-native cichlid fish in Florida Risk assessment of chanchita Cichlasoma dimerus (Heckel, 1840), a newly identified non-native cichlid fish in Florida

Cichlasoma dimerus was only recently discovered in Florida and little is known of its dispersal abilities and potential impacts. Many factors likely contribute to the variability in establishment and spread of non-native fishes in Florida, including biotic (e.g., predation and competition) and abiotic variables (e.g., cold tolerance, low-oxygen tolerance). Of the abiotic variables, cold...

Whole rock geochemistry and comparative leachability of variably bleached and red sandstones of the Permian Cutler Formation, Mesa County, Colorado Whole rock geochemistry and comparative leachability of variably bleached and red sandstones of the Permian Cutler Formation, Mesa County, Colorado

Forty samples of outcropping rock samples were collected from the Permian Cutler Formation exposed in the Sinbad Valley, Mesa County, Colorado by USGS volunteer Jon Thorson. This sample set includes 13 pairs of co-existing red unaltered and yellow-grey bleached sandstone. The decimal latitude and longitude locations of the sample collection sites are listed in the "All_Rock_Data"...

Fluvial Erosion Hazard Rapid Geomorphic Assessment Data from the Marengo Watershed, Ashland County, Wisconsin Fluvial Erosion Hazard Rapid Geomorphic Assessment Data from the Marengo Watershed, Ashland County, Wisconsin

An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss...

Earthquake triggered ground failure associated with the M7.1 2018 southcentral Alaska Earthquake (ver. 2.0, December 2023) Earthquake triggered ground failure associated with the M7.1 2018 southcentral Alaska Earthquake (ver. 2.0, December 2023)

The November 30, 2018, magnitude (Mw) 7.1 Anchorage, Alaska earthquake triggered substantial ground failure throughout Anchorage and surrounding areas (Grant et al., 2020; Jibson et al., 2020). The earthquake was an intraslab event with a focal depth of about 47 km and an epicenter about 16 km north of the city of Anchorage. Peak ground accelerations reached ∼30% g. Despite the...

Database for the geologic map of the upper Santa Cruz River basin, southern Arizona Database for the geologic map of the upper Santa Cruz River basin, southern Arizona

This digital publication contains the database, base maps, and style files used to build the geologic map of the upper Santa Cruz River basin in southern Arizona published in U.S. Geological Survey Scientific Investigations Map 3490 (Page and others, 2023). Shapefiles are also included for the user’s convenience. In the database, there are polygon features outlining the map units and...

GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool GW/SW-MST: A Groundwater/Surface-Water Method Selection Tool

The Groundwater/Surface-Water Method Selection Tool (GW/SW-MST) is a spreadsheet-based tool to help practitioners identify methods for use in groundwater/surface-water (GW/SW) exchange and hyporheic studies. GW/SW exchange and hyporheic processes are topics receiving increasing attention from the hydrologic community. Hydraulic, chemical, temperature, geophysical, and remote sensing...
