    Slocum glider data were collected during a southern Lake Michigan deployment from 2021-09-09 through 2021-09-30. The glider initially deployed from Muskegon, MI and traveled west to Milwaukee, WI. Then the glider continued southeast to buoy 45007. Near buoy 45007 there is a co-located vertical temperature mooring maintained by NOAA Great Lakes Environmental Research Laboratory. After the glider returns back to Muskegon, MI. This transect was repeated several times. After that transect was repeated a number of times the glider was retrieved. Note, the glider was deployed in areas of Lake Michigan with at least 30 m of depth. The glider collected vertical profiles of conductivity, temperature, depth, chlorophyll, colored dissolved organic matter (CDOM), backscatter, dissolved oxygen, phycocyanin, and photosynthetically active radiation (PAR) between depths of 0 and 130 m.
