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 2017-06-09 through 2019-10-10. 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. 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 data files associated with this accession end with “spar” or “subsurface” to differentiate the two locations. 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 CTD casts and nautical charts. The sensors’ depth from the surface are estimated from the total depth. Onset HOBOs were deployed and collected pressure observations across all years, but provided unreliable data and were not used to correct the sensor depths. This mooring location is one of eight CHRP (Coastal Hypoxia Research Program) moorings that collected observations during the summer season from 2017-2019.

In 2017, there was no CTD cast taken at the time of deployment. YSI EXO2 data end early, over multiple years, due to battery failure. In 2019, an AWAC ADCP sensor was deployed but damaged during the season, no data were retrieved.

Data are in text and NetCDF.

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. This research was funded by the National Oceanic and Atmospheric Administration's National Centers for Coastal Ocean Science Competitive Research Program under award NA16NOS4780209 to the University of Michigan and NOAA Great Lakes Environmental Research Laboratory to support the project “Operational Lake Erie Hypoxia Forecasting for Public Water Systems Decision Support.”
