The data in this record contains the physical and chemical vertical observational data from fixed mooring CHRP5 in the central basin of Lake Erie, Great Lakes region from 2021-06-17 through 2021-09-30. The approximate depth at CHRP5 is 15.3 m. Observations were collected at hourly or sub-hourly time intervals for water temperature and dissolved oxygen. 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.

Purpose Episodes of low dissolved oxygen are common during the summer in the bottom water of the central basin of Lake Erie. Underwater sensor moorings were deployed at eight stations across the central basin of Lake Erie to monitor oxygen conditions. Dissolved oxygen and temperature conditions at a high temporal frequency at multiple stations across Lake Erie provide the supporting data for the development of experimental hypoxia hindcast and forecast models and aid our understanding of the development and extent of hypoxia.
