Shallow Sediment Geochemistry in a Mercury-Contaminated Multi-Habitat Floodplain: Cache Creek Settling Basin, Yolo County, California (version 2.0, August 2021)
The Cache Creek Settling Basin (CCSB) is a 13.3 km2 leveed basin located at the terminal drainage of the Cache Creek watershed, immediately NE of the town of Woodland (Yolo County), California and approximately 18 km NW of Sacramento, California. The basin was constructed by the U.S. Army Corps of Engineers (completed in 1937 and modified in 1993) for the purpose of trapping suspended sediment tra
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 framework of th
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 provide e
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 lower limit o
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 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 site-level
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) groundwater sub
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.
Temporal Viral Viability Data from Avian Influenza A Viruses Maintained in Alaska Wetlands Under Experimental and Environmental Conditions
Data sets containing: (1) sample collection and influenza A virus (IAV) screening information for wild ducks, (2) water temperature data from four wetlands within the Izembek National Wildlife Refuge in Alaska, USA (3) water quality measurement from four wetlands within the Izembek National Wildlife Refuge in Alaska, USA, (4) genetic sequence data for IAVs recovered from replicate samples of wild
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 data from 27
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 Mexico an
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 comparable ecolog
