Long-term stability and thermal stress challenge of the JFE AROUSB (sn 0091). Instrument was
maintained in well circulated tank and oxygen content manipulated by alternately varying water temperature set
point between 15 and 25
o
C several times per week of deployment.
Top Panel
: Time series of AROUSB instrument
readings representing average of ten 1s burst reads at 15min intervals with discrete values for Winkler assays of
reference samples taken at sensor level.
Bottom Panel
: Offset in paired DO readings of AROUSB and Winkler
reference samples. Offsets beyond 2 mg/L (1 event) are excluded for clarity.
