Results for the EXO2 for the two Lake Michigan trials are shown in figure 16. The
instrument exhibited a positive bias in both portions of the water column but the magnitude was
higher in the cold high DO hypolimnion. Sensor equilibration time was similar between both
trials, whether equilibrated at surface or depth. The range in measurement differences between
instrument and reference was -0.32 to -0.03 mg/L for cast 2 and -0.20 to 0.11 mg/L for cast 3.
