Water physical, chemical, and biological vertical observational data at multiple levels from fixed mooring CHRP2 in the central basin of Lake Erie, Great Lakes region from 2021-06-17 to 2021-09-28 collected by National Oceanic and Atmospheric Administration, Great Lakes Environmental Research Laboratory and the Cooperative Institute for Great Lakes Research, University of Michigan (NCEI Accession 0250293)
The data in this record contains water physical, chemical, and biological vertical observational data from fixed mooring CHRP2 in the central basin of Lake Erie, Great Lakes region during the summer seasons from 2021-06-17 through 2021-09-28. The approximate depth at CHRP2 is 20.0 m. Observations were collected at hourly or sub-hourly time intervals for water temperature and dissolved oxygen and other water quality parameters. The moorings are designed in a U-shape with a spar buoy and a subsurface buoy approximately 300 ft apart. The spar buoy has a surface expression float and holds the upper water column sensors. The subsurface buoy holds the subsurface float and lower water column sensors. The vertical placement of temperature and dissolved oxygen sensors, as well as the spatial location of the mooring, varied from year to year. The total depth of the mooring location is approximated from nautical charts.
The data files associated with this accession contain the terms “spar” or “subsurface” to differentiate the two locations for each mooring. The file names end with the time resolution of the data in ISO 8601 format.
This mooring location is one of seven CHRP moorings that collected observations during the 2021 summer season. Note, these moorings have been deployed in Lake Erie's central basin during the open water season since 2017. In 2021, the CHRP7 mooring was not deployed.
