Title: Water physical and chemical vertical observational data at multiple levels from fixed mooring CHRP8 and CTD casts taken from NOAA research vessel R5501 in the central basin of Lake Erie, Great Lakes region from 2017-05-24 to 2019-10-08 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 0210741)
Abstract: The data in this record contains water physical and chemical vertical observational data from fixed mooring CHRP8 in the central basin of Lake Erie, Great Lakes region during the summer seasons from 2017-05-24 through 2019-10-08. The approximate depth at CHRP8 is 14.0 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 and 2018, CTD casts were collected during deployment of the moorings and are included in this accession as CSV and CNV files. In 2017, The temperature sensor at 7 m (serial no. 0974) recorded values out of range for the first several days of deployment, possibly because it was an old sensor. Data from the first several days of deployment were removed. In 2019, the temperature sensor at 9 m (serial no. 1656) recorded data much warmer than any other sensor, data were not included. Data are in text and NetCDF formats.
