Airborne electromagnetic, magnetic, and radiometric survey, upper East River and surrounding watersheds near Crested Butte, Colorado, 2017 Airborne electromagnetic, magnetic, and radiometric survey, upper East River and surrounding watersheds near Crested Butte, Colorado, 2017
This data release consists of 1,984 line-kilometers of airborne electromagnetic (AEM), magnetic data and radiometric data collected from October to November 2017 in the upper East River and surrounding watersheds in central Colorado. The U.S. Geological Survey contracted Geotech Ltd. to acquire these data as part of regional investigations into the geologic structure and hydrologic...
Acoustic detection performance of gliding robotic fish in Higgins Lake, Michigan, USA, 2016-2018 Acoustic detection performance of gliding robotic fish in Higgins Lake, Michigan, USA, 2016-2018
An acoustic telemetry receiver was mounted on a gliding robotic fish, a novel type of autonomous underwater vehicle (AUV) during a series of field trials in a freshwater lake. Like underwater gliders, gliding robotic fish (dubbed GRACE, for Gliding-Robot-ACE) achieve locomotion primarily through buoyancy-driven gliding or spiraling. They are also equipped with an active tail fin that can...
Comparison of methane concentration and stable carbon isotope data for natural samples analyzed by discrete sample introduction module - cavity ring down spectroscopy (DSIM-CRDS) and traditional methods Comparison of methane concentration and stable carbon isotope data for natural samples analyzed by discrete sample introduction module - cavity ring down spectroscopy (DSIM-CRDS) and traditional methods
A discrete sample introduction module (DSIM) was developed and interfaced to a cavity ring-down spectrometer to enable measurements of methane and CO2 concentrations and 13C values with a commercially available cavity ring-down spectrometer (CRDS). The DSIM-CRDS system permits the analysis of limited volume (5 - 100-ml) samples ranging six orders-of-magnitude from 100% analyte to the...
Campaign GPS measurements on the Island of Hawai`i collected by the Hawaiian Volcano Observatory in 2020 Campaign GPS measurements on the Island of Hawai`i collected by the Hawaiian Volcano Observatory in 2020
This dataset includes raw and rinex data from 2020 campaign gps data from the Island of Hawai`i in 2020. There was a total of 57 sites occupied. All data are included along with metadata, log sheets and raw/rinex data.
Fish movement and colonization in the Wyoming Range 2018-2019 Fish movement and colonization in the Wyoming Range 2018-2019
Fish colonization ability may be one factor affecting population resilience after disturbance. We conducted displacement experiments in headwater streams in Wyoming, U.S.A. to evaluate mottled sculpin (Cottus bairdii) and mountain sucker (Catostomus platyrhynchus) colonization ability. Specifically, we (1) determined if fish could colonize sites rapidly after displacement, (2) evaluated...
Detections of Fecal Indicator Bacteria and DNA Sequencing of Selected Bacterial Growths in Samples from the Madera/Chowchilla-Kings Domestic Aquifer Study unit, 2014: Results from the California GAMA Priority Basin Project Detections of Fecal Indicator Bacteria and DNA Sequencing of Selected Bacterial Growths in Samples from the Madera/Chowchilla-Kings Domestic Aquifer Study unit, 2014: Results from the California GAMA Priority Basin Project
These data describe microbiological analyses performed on groundwater samples from domestic drinking water supply collected from 42 groundwater wells in the Central Valley of California. Samples were collected between January 2014 and April 2014 for the Groundwater Ambient Monitoring and Assessment (GAMA) program priority basin assessment of the Madera, Chowchilla, and Kings (MACK)...
Summary and synthesis of 15 years of the Amphibian Vital Sign monitoring in the National Capital Region Inventory and Monitoring Network Summary and synthesis of 15 years of the Amphibian Vital Sign monitoring in the National Capital Region Inventory and Monitoring Network
This data set is comprised of four files related to the counts of amphibian species in the National Capital Region of the United States. Data was obtained from surveys of both lentic (wetland) and lotic (stream) sites within national parks.

Hydrologic simulations using projected climate data as input to the Precipitation-Runoff Modeling System (PRMS) in the Upper Rio Grande Basin Hydrologic simulations using projected climate data as input to the Precipitation-Runoff Modeling System (PRMS) in the Upper Rio Grande Basin
The Rio Grande Basin Study (Basin Study) is a stakeholder-led project funded by the U.S. Bureau of Reclamation to develop climate adaptation strategies to address the growing gap between water supply and demand in the Upper Rio Grande Basin in Colorado, New Mexico, and Texas. The role of the USGS in the Basin Study is to simulate historic and future streamflow using projected climate...
Cold-water Coral Microbiomes (Acanthogorgia spp. Desmophyllum dianthus, and Lophelia pertusa) from the Gulf of Mexico and Atlantic Ocean off the Southeast Coast of the United States-Raw Data Cold-water Coral Microbiomes (Acanthogorgia spp. Desmophyllum dianthus, and Lophelia pertusa) from the Gulf of Mexico and Atlantic Ocean off the Southeast Coast of the United States-Raw Data
The files in this data release are the raw 16S rRNA gene amplicon DNA sequence files from 28 samples of deep-sea corals Acanthogorgia aspera, Acanthogorgia spissa, Desmophyllum dianthus, and Lophelia pertusa, as well as an extraction blank for the Qiagen PowerBiofilm kit used for DNA extraction. The samples were collected during four research cruises from various locations in the Gulf of...
Ecological community datasets used to evaluate the presence of trends in ecological communities in selected rivers and streams across the United States, 1992–2017 Ecological community datasets used to evaluate the presence of trends in ecological communities in selected rivers and streams across the United States, 1992–2017
In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water Quality Program. One of the major goals of the NAWQA project is to determine how water quality and ecological conditions change over time. To support that goal, long-term consistent and...
Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock for Geohydrology and Water Quality of the Stratified-Drift Aquifer in West Branch Cayuga Inlet and Fish Kill Valleys, Town of Newfield, Tompkins County, New York, July 2011 - November 2016 Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock for Geohydrology and Water Quality of the Stratified-Drift Aquifer in West Branch Cayuga Inlet and Fish Kill Valleys, Town of Newfield, Tompkins County, New York, July 2011 - November 2016
From July 2011 to November 2016, the U.S. Geological Survey, in cooperation with the Town of Newfield and the Tompkins County Planning Department, collected horizontal-to-vertical seismic surveys at 58 locations in the West Branch Cayuga Inlet and Fish Kill valleys to help determine thickness of unconsolidated deposits and depth to bedrock. The HVSR technique, commonly referred to as the...
