Shapefile and summary tables for the approximate inland extent of saltwater intrusion at the base of the Biscayne aquifer in 2022, Miami-Dade County, Florida
The U.S. Geological Survey (USGS) cooperated with Miami-Dade County to map the approximate inland extent of saltwater intrusion in the Biscayne aquifer in eastern Miami-Dade County, Florida in 2022. This map is a continuation of a series of maps, the most recent of which was published in 2018, which have helped to track the position of the saltwater interface over time and have improved understand
Plain pocketbook (Lampsilis cardium) glochidia counts and transformation rates collected during laboratory exposures to agriculture and urban contaminant mixtures and measured contaminant concentrations, 2018
This data release includes datasets provided by the Woolnough Laboratory at Central Michigan University. These data were collected as a part of a laboratory exposure experiment, conducted in 2018, examining the effects of agricultural and urban contaminant mixtures on two life stages (larval and juvenile) of the freshwater mussel, plain pocketbook (Lampsilis cardium), using largemouth bass (Microp
Spatial data of artisanal mining riverine dredges using three different Synthetic Aperture Radar detection approaches on the Madeira River, Brazil
Three semi-automated detection approaches using Sentinel-1 Synthetic Aperture Radar (SAR) have been performed to identify artisanal and small-scale mining (ASM) riverine dredges on the Madeira River in Brazil. The methods are: i) Search for Unidentified Maritime Objects (SUMO), an established method for large ocean ship detection; and two techniques specifically developed for riverine environments
Little Brown Bats (Myotis lucifugus) weights and Ct values for SARS-CoV-2 Infection challenge
Little brown bat (Myotis lucifugus) weights and SARS-CoV2 test results were collected as part of study to assess transmission potential of SARS-CoV2 in North American bat populations. It has been proposed that the SARS-CoV-2 virus originated in Asian bats and subsequently spread through human populations as a pandemic. There is concern that infected humans could transmit the virus to native North
Tiltmeter data from Mauna Loa summit stations (BLB, MCC, MLO, MOK, SLC) from January 1 to December 31, 2021
Tiltmeter data from stations BLB, MCC, MLO, MOK, and SLC from January 1 to December 31, 2021.
Tiltmeter data from Mauna Loa summit stations (BLB, MCC, MLO, MOK, SLC) from January 1 to December 31, 2022
Tiltmeter data from stations BLB, MCC, MLO, MOK, and SLC from January 1 to December 31, 2022, spanning the Mauna Loa 2022 eruption and unrest.
Post-fire plot-level vegetation cover measurements in the western United States
These data consist of plot-level plant species cover measurements from numerous targeted post-fire vegetation studies across the western United States. This data release includes two data tables. The first data table: 'postfire_vegplot_dataset.csv', consists of absolute percent live foliar cover measurements of all plant species within plots from targeted post-fire vegetation studies, or 'datasets
Sap flux and biophysical measurements of select trees at Panola Mountain Research Watershed, Georgia, 2019
This data release contains a zipped folder with two comma delimited data files and two companion metadata files. The data files are: 1.) sap_flux_data.csv and; 2.) biophysical_characteristics_of_instrumented_trees.csv. The sap flux data were stored in data loggers every 10-minutes for 15 riparian trees. Sap flux was estimated using heat-pulse velocity sensors at three depths into the xylem of each
Daily Mean Runoff and Precipitation at Panola Mountain Research Watershed, Stockbridge, GA., water years 1986–2019
This data release contains two tabular data files and associated metadata. One tabular data file has mean daily runoff from the lower stream gage and total daily precipitation from the Panola Mountain Research Watershed.The other tabular data file contains data edit codes, their descriptions, and the associated data quality code.
Expanded dataset of measurements to be used in evaluating consequences for flight control and stability induced by attachment of bio-logging devices to birds and bats
Bio-logging is central to study of wildlife, but questions remain about minimization of effects from bio-logging devices. Rarely considered are changes bio-logging devices induce on an animal’s center of mass (COM) and resulting losses of flight control and stability. In a related paper (Katzner and Young 2024), we applied established aeronautical principles to estimate how the COM of a flying bir
Swim chamber respirometry, aerobic scope, and thermal tolerance experiments with two latitudinally-separated cisco (Coregonus artedi) populations 2022-2023
These data include aerobic scope and thermal tolerance measurements from two cisco (Coregonus artedi) populations to evaluate performance and potential adaptation to warming Great Lakes habitats. Cisco come from two stock sources: 1) a northern latitude Lake Huron stock collected as gametes from Les Cheneaux Islands, MI, USA in 2015 and raised in a USGS aquaculture lab in Ann Arbor, MI, and 2) a s
Estimates of avian influenza transmission risk across the wild waterfowl - domestic poultry interface (ver. 2.0, May 2024)
These data describe the creation, execution, and results of an effort to model the risk of avian influenza transmission across the wild waterfowl - domestic poultry interface at weekly intervals for the contiguous United States.
