    • 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 2014-05-05 to 2020-08-12 (NCEI Accession 0282935)

    Metadata Updated: November 1, 2023

    Two moorings were deployed near the M45 station by the NOAA Great Lakes Environmental Research Laboratory (GLERL) from 2014 through 2020. 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 first mooring, “M45”, is an oceanographic mooring containing a temperature string. The second mooring, “M45X” mooring is a physical and biological mooring that collects temperature and fluorometer measurements over the winter. The approximate depth of this mooring location was 45 m.

    The M45 deployment’s temperature string collects vertical water temperatures at hourly time intervals at multiple depths by Sea-Bird 39 and HOBO Tidbits thermistors. The temperature string at this location was deployed only during 2014-2015. The data files for this mooring contain the station name “noaa-glerl-michigan-lter-m45-” in the file name.

    The M45X mooring collects surface and bottom temperature and fluorometer measurements hourly. The temperature sensors were Sea-Bird 39, HOBO Onset, and HOBO Tidbits thermistors. 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.

    All measurements were collected continuously during the deployments. Note the deployments are not continuous throughout this time period. Several sensors shown on the mooring diagrams failed during deployments, those data are not included in this accession. 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.
