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...
