Stream salamanders in abandoned mine habitats of New River Gorge National Park and Preserve Stream salamanders in abandoned mine habitats of New River Gorge National Park and Preserve
Stream-like habitats in abandoned mine areas of New River Gorge National Park and Preserve were surveyed for stream salamanders in fall 2024. Methods included visual encounter surveys of transects up to 25m within stream-like mine water discharges in the Nuttallburg, Fayette Station, Hawks Nest Connector, and New River Gorge Bridge areas of the park. All stream salamander species...
Chirp sub-bottom data collected in the Great Salt Lake, Utah during USGS field activity 2021-615-FA Chirp sub-bottom data collected in the Great Salt Lake, Utah during USGS field activity 2021-615-FA
This data release contains 57 high-resolution chirp sub-bottom profiles collected in the southern Great Salt Lake, Utah, by the U.S. Geological Survey in June 2021 during field activity 2021-615-FA. The dataset was acquired to image subsurface sedimentary structures and stratigraphy in support of efforts to characterize past earthquake events along the Great Salt Lake Fault, contributing...
Model Archive Summary for Suspended-Sediment Concentration at station 11509500, Klamath River at Keno, Oregon, water years 2019-2024 Model Archive Summary for Suspended-Sediment Concentration at station 11509500, Klamath River at Keno, Oregon, water years 2019-2024
This model archive summary (MAS) document and model calibration dataset describes a surrogate model used to compute suspended sediment concentrations at USGS streamgage 11509500 for water years 2019-2024. The methods used follow USGS guidance as referenced in Office of Surface Water (OSW)/Office of Water Quality (OWQ) technical memoranda 2016.07 (https://water.usgs.gov/osw/pubs/memo...
Per- and polyfluoroalkyl substance concentrations in water, sediment, and tissue in a stream food web contaminated by food processing facility wastewater, 2021-2022 Per- and polyfluoroalkyl substance concentrations in water, sediment, and tissue in a stream food web contaminated by food processing facility wastewater, 2021-2022
This dataset contains chemistry results for water, sediment, and various tissue samples collected upstream and downstream of a PFAS source (treated industrial wastewater). Samples were analyzed by a USGS laboratory (National Water Quality Laboratory; Denver, CO) and SGS-AXYS (Sidney, BC, Canada). Concentration, surrogate recovery, and blank results are presented within.
Stand structure for Joshua trees (Yucca brevifolia and Y. jaegeriana) in the eastern Mojave Desert of California, 2022 plot data Stand structure for Joshua trees (Yucca brevifolia and Y. jaegeriana) in the eastern Mojave Desert of California, 2022 plot data
These data were compiled to measure the stand structure, including age class distribution, of Joshua tree (Yucca brevifolia and Y. jaegeriana) as measured on 61 1000 m2 plots.The objective of our study was to provide the U.S. Fish and Wildlife Service with demographic data, particularly on recruitment, of the Joshua trees for their use in decisions that the Service makes for the...
Swan Lake National Wildlife Refuge pre-restoration orthoimagery and elevation products, spring 2025 Swan Lake National Wildlife Refuge pre-restoration orthoimagery and elevation products, spring 2025
The products presented here document conditions at the Swan Lake National Wildlife Refuge, Missouri from March to May, 2025. Imagery was collected to document conditions at areas in the north (“N_wetlands”) and east (“E_wetlands”) portions of the refuge prior to restoration to modify hydrology and habitat and improve future management capabilities. Imagery also captured a section of...
Water temperature, air temperature, sensor depth, and select flow and temperature metrics. Data from water year 2020 for the Stormwater Action Monitoring Puget Small Streams Project (ver. 1.1, March 2026) Water temperature, air temperature, sensor depth, and select flow and temperature metrics. Data from water year 2020 for the Stormwater Action Monitoring Puget Small Streams Project (ver. 1.1, March 2026)
These data were collected as part of the Stormwater Action Monitoring (SAM) program's Puget Small Streams (PSS) status and trends program. The data presented here were collected from 29 sites during water year 2020 for water temperature, air temperature, and sensor depth. Sensor depth was used as a surrogate for water depth and represents the arbitrary depth of water above the sensor...
Method comparison for the detection of environmental DNA from three species of unionid mussels in a mesocosm Method comparison for the detection of environmental DNA from three species of unionid mussels in a mesocosm
Data describe a mesocosm study for the detection of mucket (Ortmanniana ligamentina), fatmucket (Lampsilis siliquoidea), and giant floater (Pyganodon grandis) freshwater mussel environmental DNA (eDNA). Water samples were collected on two different days in September of 2022 from a CERC pond containing O. ligamentina, L. siliquoidea, and P. grandis then analyzed for the presence of eDNA...
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...
