Data collected from wastewater effluent sampling and on-site fish exposures: trace organic contaminant concentrations, bacteria concentrations, and fish responses - Hutchinson, Minnesota, 2022 Data collected from wastewater effluent sampling and on-site fish exposures: trace organic contaminant concentrations, bacteria concentrations, and fish responses - Hutchinson, Minnesota, 2022
This dataset consists of trace organic contaminant concentrations and bacteria counts in wastewater effluents, and observed responses in fish exposed to effluents. The study was conducted from April to September 2022 at a facility located in Hutchinson, Minnesota. Nine pairs of primary-treated, activated sludge secondary treated, and membrane bioreactor secondary treated wastewater were
Model application and calibration load data for seasonally dynamic total nitrogen and total phosphorus SPARROW models developed for watersheds draining to Washington waters of the Salish Sea, 2005 through 2020 Model application and calibration load data for seasonally dynamic total nitrogen and total phosphorus SPARROW models developed for watersheds draining to Washington waters of the Salish Sea, 2005 through 2020
This data release contains two data sets: 1) the model application data for a set of dynamic total nitrogen (TN) and total phosphorus (TP) SPARROW (SPAtially Referenced Regression On Watershed attributes; Schwarz and others, 2006, https://doi.org/10.3133/tm6B3) load models that were developed for watersheds draining to Washington waters of the Salish Sea (Puget Sound region) 2005 through...
Micro-Raman spectroscopy parameters investigating biochar's carbon stability and structural development in comparison to fusinite and semifusinite Micro-Raman spectroscopy parameters investigating biochar's carbon stability and structural development in comparison to fusinite and semifusinite
Semifusinite and fusinite macerals are formed through carbonization of plant material in naturally occurring wildfires. Both macerals, belonging to the inertinite maceral group, are carbon-rich and oxygen-poor, and are typical constituents of charcoal. The charring of plant material into charcoal serves as nature’s method for storing carbon over geological timescales. The permanence and...
Sr/Ca, Oxygen Isotope, and Linear Extension Data for Five Holocene Orbicella faveolata Corals from Dry Tortugas and Marquesas Keys, Florida, USA Sr/Ca, Oxygen Isotope, and Linear Extension Data for Five Holocene Orbicella faveolata Corals from Dry Tortugas and Marquesas Keys, Florida, USA
This data release contains new, 40–70-year long sub-annual strontium-to-calcium ratio (Sr/Ca) records and linear extension measurements from five mid-to-late Holocene, Orbicella faveolata corals from the Dry Tortugas National Park (DT) and Marquesas Keys (MK), Florida (FL). U.S. Geological Survey (USGS) researchers used these Sr/Ca data to calculate sea-surface temperature (SST) using...
Analysis of fish PIT tag detections from 2008-2024 at the Link River Dam fish ladder in the Upper Klamath River Basin, Oregon Analysis of fish PIT tag detections from 2008-2024 at the Link River Dam fish ladder in the Upper Klamath River Basin, Oregon
Passive integrated transponder (PIT) detections across the Upper Klamath River Basin were combined from all fish that were detected making a passage attempt at the Link River Dam fish ladder from 2008 - 2024. In July 2007, four PIT tag antennas (FS1001 Muliplexer transceiver [MUX] units) arrays which were originally installed by Biomark. In October 2023, antennas were upgraded to Biomark...
Airborne Magnetic and Radiometric Survey, Colorado Mineral Belt, Mid Block, 2023 Airborne Magnetic and Radiometric Survey, Colorado Mineral Belt, Mid Block, 2023
This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over the central portion of the Colorado Mineral Belt, central Colorado. The Colorado Mineral Belt is a broad, northeast-southwest trending alignment of historic mining districts that have produced multiple types of commodities, including critical minerals that...
