Oceanographic and biological water parameter data collected from the M45X mooring in Lake Michigan, Great Lakes region to support the long-term ecological research Muskegon transect studies by NOAA Great Lakes Environmental Research Laboratory from 2020-10-08 to 2021-06-29 (NCEI Accession 0255820)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:10 AM | Dataset Last Updated: August 30, 2022 at 12:00 AM
One mooring was deployed near the M45 station by the NOAA Great Lakes Environmental Research Laboratory (GLERL) from October 2020 to June 2021. These observations support the GLERL Long-Term Ecological Research program. The M45 station is part of the Muskegon Transect in Lake Michigan near the NOAA Lake Michigan Field Station, Muskegon, MI. The “M45X” mooring is a physical and biological mooring that collects temperature and fluorometer measurements near the surface and bottom over the winter. The approximate depth of this mooring location was 45 m. The M45X mooring collects surface and bottom temperature and fluorometer measurements hourly. The temperature sensors were Sea-Bird 39. The Wet Labs fluorometers measured voltage, which were converted to chlorophyll concentrations. Please see the “Supplemental Information” for more information about the chlorophyll concentrations. The data files for this mooring contain the station name “noaa-glerl-michigan-lter-m45x-” in the file name. Note, during the 2020-2021 deployment a fluorometer was deployed at the bottom of the M45X mooring, but only collected data for the first several days. These data are not included in the accession. All measurements were collected continuously during this time period. Included in this data package are two data formats, netCDF and CSV. Metadata is included in the netCDF file, the CSV files also contain a data dictionary explaining the column headings.
