The calculated drift rate in instrument response for the entire deployment period was -0.079
mg/L/d (r
2
= 0.49; p<0.0001).
In contrast, the drift rate for the first 35 days of the deployment was
much less, averaging only -0.016 mg/L/d (r
2
= 0.54; p<0.001). In both cases the rate would
include any biofouling effects as well as any electronic or calibration drift.
