Microcosm experiment data of microcystin-degrading bacteria in Lake Erie source waters and drinking-water plants, 2015-18 Microcosm experiment data of microcystin-degrading bacteria in Lake Erie source waters and drinking-water plants, 2015-18
In 2015-2018, the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency Great Lakes Restoration Initiative investigated the biodegradation of microcystins in source waters and sand filters from drinking-water plants in the Western Lake Erie Basin. Four source waters and three sand filtrate samples were collected from the intakes and sand filters of...
The Stable Carbon Isotope Dataset of Individual Foraminifer (Orbulina universa) Shells Measured by Secondary Ion Mass Spectrometry and Gas-Source Mass Spectrometry The Stable Carbon Isotope Dataset of Individual Foraminifer (Orbulina universa) Shells Measured by Secondary Ion Mass Spectrometry and Gas-Source Mass Spectrometry
This data release contains data associated with the journal article, “Comparison of δ13C Analyses on Individual Foraminifer (Orbulina universa) Shells by Secondary Ion Mass Spectrometry and Gas-Source Mass Spectrometry”. Data tables are comprised of stable carbon isotope (δ13C) measurements of planktic foraminifer (Orbulina universa) shells measured by secondary ion mass spectrometry...
Composite multibeam bathymetry surface and data sources of the central Cascadia Margin offshore Oregon Composite multibeam bathymetry surface and data sources of the central Cascadia Margin offshore Oregon
In 2018 and 2019 the NOAA ships Rainier and Fairweather collected multibeam bathymetry data in 4 areas along the central Cascadia Margin offshore Oregon as part of a cooperative project between the U.S. Geological Survey, Pacific Coastal and Marine Science Center and NOAA. These regions were combined with other publicly available multibeam bathymetry data. The surface was generated to...
Historical simulated snowpack and other hydrometeorology data at 30 m for the Crown of the Continent and vicinity, United States and Canada, water years 1981-2020 Historical simulated snowpack and other hydrometeorology data at 30 m for the Crown of the Continent and vicinity, United States and Canada, water years 1981-2020
This data release contains historical SnowModel (Liston and Elder, 2006) output for the Crown of the Continent and surrounding areas in Montana, USA; and Alberta and British Columbia, Canada from September 1, 1981 through August 31, 2020. Fifteen daily variables were simulated or derived for this release: (1) snow water equivalent (swed), (2) liquid precipitation (rpre), (3) solid...
Bathymetry, backscatter intensity, and benthic habitat offshore of Cape Mendocino, California Bathymetry, backscatter intensity, and benthic habitat offshore of Cape Mendocino, California
Survey data collected for this data release were used to create maps of surficial geology and benthic habitat as part of the USGS California Seafloor Mapping Program, a collaboration with California State University Monterey Bay (CSUMB) and the National Oceanic and Atmospheric Administration (NOAA). Funding was provided by the California Ocean Protection Council. These data are intended...
Louisiana Outer Coast Restoration Project – 2022 habitat map, North Breton Island Louisiana Outer Coast Restoration Project – 2022 habitat map, North Breton Island
This data release includes 2022 data for the Louisiana Outer Coast Restoration Project for North Breton Island. Specifically, this data release includes a detailed habitat map, general habitat map, georeferenced imagery, and a bare-earth digital elevation model (DEM) developed from light detection and ranging data. These habitat maps are developed using the methods and classification...
