The data in this record contains the physical and chemical vertical observational data from fixed mooring CHRP3 in the central basin of Lake Erie, Great Lakes region from 2022-05-19 through 2022-10-05. The approximate depth at CHRP3 is 15.4 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 when needed.
This mooring location is one of seven CHRP moorings that collected observations during the 2022 summer season. Note, these moorings have been deployed in Lake Erie's central basin during the open water season since 2017. In 2022, the CHRP7 mooring was not deployed.
