    • Physical, chemical, and biological water quality observation data at multiple levels from an array of fixed moorings to support hypoxia research in the central basin of Lake Erie, Great Lakes region collected by the NOAA Great Lakes Environmental Research Laboratory and the Cooperative Institute for Great Lakes Research, University of Michigan, since 2017

    Metadata Updated: March 1, 2026

    Episodes of low dissolved oxygen are common during the summer in the bottom water of the central basin of Lake Erie. Dissolved oxygen and temperature observations at a high temporal frequency and a broad spatial extent provide the supporting data for the development of experimental hypoxia hindcast and forecast models and aid our understanding of the development and extent of hypoxia. Underwater sensor moorings were deployed across the central basin of Lake Erie to monitor oxygen conditions by the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory and the Cooperative Institute for Great Lakes Research (CIGLR), University of Michigan. Moorings were deployed during the summer season beginning in 2017 to collect in situ data for the following parameters, water temperature, dissolved oxygen, water current speed and direction, specific conductivity, pH, turbidity, oxidation-reduction potential (ORP), chlorophyll, phycocyanin, dissolved organic matter, and phosphorus at hourly or sub-hourly time intervals.
