The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | 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) |
| Abstract: | 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. |

| Supplementary information: | Data from the fluorometers represents raw output from the sensor. This data was then converted to chlorophyll fluorescence by applying linear scaling constants. The fluorometers deployed at this location were calibrated by the manufacturer WetLabs, in December of 2019 using a Thalassiora weissflogii phytoplankton culture. The characterization sheets for each instrument are included in this data accession. No further calibrations for freshwater environments or specific chlorophyll species were performed in our Laboratory prior to deployment. The fluorometer chlorophyll values should be used as approximate values to understand trends in chlorophyll over the deployment period. Do not use the fluorometer chlorophyll values as exact values, as actual environmental conditions will affect the calibration scaling constants. Extracted chlorophyll values can be found in the water quality sampling data collected for this and a nearby location. |
