Grand Calumet River Area of Concern Metabarcoding Data Grand Calumet River Area of Concern Metabarcoding Data
The Grand Calumet River flows through northwestern Indiana and was designated an EPA Area of Concern (AOC) in 1987. There are multiple legacy pollutants in the river including but not limited to heavy metals and PCBs. To investigate potential causes and patterns of eutrophication in the river, water samples were collected for 16S rRNA microbial and eukaryotic 18S rRNA amplicon sequencing...
Geochemical, grain size, lithological, diatom, bathymetric, and age model data for Wildcat Lake, Point Reyes National Seashore 2021 Geochemical, grain size, lithological, diatom, bathymetric, and age model data for Wildcat Lake, Point Reyes National Seashore 2021
These data are the geochemical (from X-ray fluorescence spectrometry), grain size, lithological (loss on ignition), diatom assemblages (taxa counts), bathymetric, and radioactive isotopes (210-Pb, 137Cs) from sediments from Wildcat Lake, Point Reyes National Seashore, California, USA starting in 2021. Taken together, they provide evidence for extreme precipitation events linked to...
Monthly point-source nutrient loads within the watersheds draining to Puget Sound and the Strait of Juan de Fuca, Washington, 2005 – 2020 Monthly point-source nutrient loads within the watersheds draining to Puget Sound and the Strait of Juan de Fuca, Washington, 2005 – 2020
This data release contains estimated monthly point-source nutrient loads for 97 municipal wastewater treatment plants, 20 industrial facilities, and 46 fish hatcheries and other aquaculture facilities that discharge within the watersheds draining to Puget Sound and the Strait of Juan de Fuca in Washington, or discharge directly to those water bodies. The data, which cover the years 2005...
Measures of adenosine triphosphate in sperm from common carp (Cyprinus carpio) in spring and fall 2010 from Lake Mead, Arizona and Nevada, USA Measures of adenosine triphosphate in sperm from common carp (Cyprinus carpio) in spring and fall 2010 from Lake Mead, Arizona and Nevada, USA
Data include values obtained from files that were generated in the analysis of ATP levels from sperm derived from Common Carp. Data were obtained with by using an ATP-binding luciferase assay, whereby standard curves were generated and experimental samples were analyzed per day of standard curve generation. The luminescence intensities were recorded in relative light units (RLUs) and ATP
Sperm quality biomarkers from common carp (Cyprinus carpio) in spring and fall 2010 from Lake Mead, Arizona and Nevada, USA Sperm quality biomarkers from common carp (Cyprinus carpio) in spring and fall 2010 from Lake Mead, Arizona and Nevada, USA
Reproductive condition of male fish is reflected by gonadal tissues and cell quality biomarkers. Common Carp from locations in the Lake Mead National Recreation Area in 2010 were collected, the biological characteristics of sperm and testicular tissues were analyzed from male fish. Raw data are provided in the form of flow cytometry files and other scored data from microscopy. Data are...
Coastal Multibeam Bathymetry Data Collected in August 2022 From Breton Island, Louisiana Coastal Multibeam Bathymetry Data Collected in August 2022 From Breton Island, Louisiana
As part of the restoration monitoring component of the Deepwater Horizon early restoration project, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS–SPCSMC), conducted a bathymetric survey near Breton Island, Louisiana (LA). During this study, multibeam bathymetry data were collected aboard the research vessel (R...
