Magnetotelluric data from the Clear Lake Region, Northern California Magnetotelluric data from the Clear Lake Region, Northern California
The Clear Lake Volcanic Field (CLVF) in northern California is a young (2 Ma-0.008 Ma) volcanic system that could be hazardous upon eruption. Magnetotellurics (MT) is a passive electromagnetic geophysical method that measures subsurface electrical resistivity by recording the Earth's electrical response to natural time varying magnetic fields. To further understand the magmatic system of...
Mercury in emergent odonates and midges of the Prairie Pothole wetlands of North Dakota, USA Mercury in emergent odonates and midges of the Prairie Pothole wetlands of North Dakota, USA
This data release is an extension of a previous data release (https://doi.org/10.5066/P971S7IV) that expands the collected data to include tissue mercury concentrations for adult aquatic insects emerging from wadable wetlands in cropland and grassland landscapes of the Prairie Pothole region (n = 15 wetlands in 2016). These data were collected at the same time as the other data (analyzed...
Elevation Data Across San Francisco Bay-Delta Wetlands Elevation Data Across San Francisco Bay-Delta Wetlands
This data release includes high resolution in-situ elevation data collected in wetlands and adjacent ecosystems throughout the San Francisco Bay from 2015 to 2024. Elevation data were collected using real-time kinematic global positioning system receivers.
Chemical and biological data from chronic bioassays with native Spea multiplicata exposed to field-collected water or sediment from the Pinyon Plain Mine containment pond in Arizona, USA, or single metals in water-only tests Chemical and biological data from chronic bioassays with native Spea multiplicata exposed to field-collected water or sediment from the Pinyon Plain Mine containment pond in Arizona, USA, or single metals in water-only tests
The dataset reports biological endpoints (survival, growth, developmental stage, and body burden of selected metals) for larval spadefoot toads (Spea multiplicata) in laboratory-based exposures to 1) field-collected water or sediment from a containment pond at the Pinyon Plain Mine in Arizona, USA, during its pre-production phase and 2) six concentrations of copper or cobalt in water...
Regional airborne electromagnetic and magnetic surveys of the Basin and Range Province in Nevada, Oregon, and California, 2022-2023 Regional airborne electromagnetic and magnetic surveys of the Basin and Range Province in Nevada, Oregon, and California, 2022-2023
Airborne electromagnetic (AEM) and magnetic survey data were collected from December 2022 through March 2023 over a distance of 11,079 line kilometers in western Nevada and eastern California; central Nevada; and northern Nevada and southeastern Oregon. These data were collected in support of the U.S. Geological Survey (USGS) Earth Mapping Resources Initiative (Earth MRI), which aims to...
Detection of Ortmanniana ligamentina male mitotype DNA from a mesocosm during a natural spawning event Detection of Ortmanniana ligamentina male mitotype DNA from a mesocosm during a natural spawning event
Data describe a mesocosm study for the detection of Mucket (Ortmanniana ligamentina) female and male mitotype environmental DNA (eDNA) during a spawning event. Water samples (approximately 1L) were collected every Monday and Thursday for 4 weeks during August 2021 from a pond located at Columbia Environmental Research Center containing O. ligamentina and analyzed for the presence of sex...
Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in a Missouri River Oxbow Lake, Creve Coeur Lake, 2023 September 20 Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in a Missouri River Oxbow Lake, Creve Coeur Lake, 2023 September 20
In September 2023, the USGS demonstrated the use of side-scan sonar to image large densities of invasive carp in Creve Coeur Lake, Maryland Heights, Missouri, USA. A 400-meter reach was surveyed using a Humminbird Helix sonar system. Proprietary sonar data were converted to PNG image files (i.e., rectified and speed-corrected) using SonarTRX Pro. The resulting data set includes one CSV...
Amino Acid Profiles of Complex Compounds for Development of Black Carp and Grass Carp baits or attractants Amino Acid Profiles of Complex Compounds for Development of Black Carp and Grass Carp baits or attractants
The data represent the common proteinogenic and non-proteinogenic amino acid composition of eight baits, both agriculture and organismal that are anticipated for testing Black Carp and Grass Carp attraction. Baits were identified based on prior literature on species diet and reported use in commercial fisheries. The data also include the crude protein value of each bait type.
Acute Toxicity of Carbon Dioxide to Juvenile Red Swamp Crayfish (Procambarus clarkii) Acute Toxicity of Carbon Dioxide to Juvenile Red Swamp Crayfish (Procambarus clarkii)
This study evaluated the use of dissolved carbon dioxide as a control method for juvenile red swamp crayfish (Procambarus clarkii). Four concentrations of CO2 and a control were administered to 18 test tanks over a 96-hour period. Red swamp crayfish were observed for behavioral changes during the exposure and were assessed for mortality 24 hours post treatment. Datasets include daily...
Hall sensor data to monitor Fusconaia flava burrowing behavior in a flume experiment Hall sensor data to monitor Fusconaia flava burrowing behavior in a flume experiment
We conducted a fluvial experiment to identify how mussel shells along river size gradients vary morphologically and respond to different flow regimes. Using individual Fusconaia flava mussels collected from upper and lower reaches of the Gasconade River in central Missouri, USA, we conducted hydraulic flume experiments to quantify burrow position and behavior response to changing flow...
Data from surface water and sediment nutrient processing experiments associated with the Maumee River (Toledo, OH) during the 2021 growing season Data from surface water and sediment nutrient processing experiments associated with the Maumee River (Toledo, OH) during the 2021 growing season
River-to-lake transitional zones or rivermouths are biogeochemically active sections of the aquatic continuum that are often understudied compared to their adjoining environments. Internal nutrient loading from these transitional zones may be a considerable source of nutrients to lakes and disconnect upstream management initiatives from in-lake improvements. To contextualize internal...
eDNA shedding rates for juvenile and subadult black carp fed a commercial diet or a Corbicula mussel diet in a laboratory setting eDNA shedding rates for juvenile and subadult black carp fed a commercial diet or a Corbicula mussel diet in a laboratory setting
Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding rates for subadult and juvenile black carp (Mylopharyngodon piceus) at different biomass densities and fed different quantities of food from water samples collected in the laboratory. Parameters described include descriptions of laboratory collected water samples that were tested to estimate
