successful deployment on 11/17/2018
Calibration data from June 2017 onward
Data Portal
24th deployment, near Coast Guard buoy.
Sailboat race starting at buoy interfered with
profiling and limited to 80 ft. 03/24/2019.
Executed with new EXO1 (without full
complement of sensors). EXO2 was being
deployed at WIES (see mooring data page).
Article on CDOC mooring deployment
25th deployment via drifting boat at
Avalon. Cold and wet day. EXO2
deployed with redundant pH and
temp/conductivity sensors.

Conductivity was not calibrated
correctly for both sensors and all  
quantities derived from conductivity
are incrorrect.
