The global response of the AroUSB for all nine temperature-salinity trials is shown in
figure J. In general, readings are well correlated across the entire range of DO concentrations
(hypoxic to supraoxic) covering all temperature and salinity ranges tested. Highlighted deviation
likely reflects bubble contamination of the sensor foil
.
A linear regression of the data (n=377; r
2
=
0.965; p<0.0001) produced a slope of 1.015 and intercept of 0.098. Highlighted data were omitted
from the regression because of expected bubble contamination.
Figure J.
Concordance of JFE AROUSB (sn 0091) oxygen measures paired with discrete Winkler DO reference
samples. Dotted line represents perfect agreement between the two measures.
Individual response slopes and intercepts of instrument versus reference DO for each of the
laboratory trials are summarized in Table 5. Slopes were similar across all three salinity trials when
averaged across temperature. The response slope was slightly higher for the 30
o
C trials (mean = 1.11)
versus the 5 and 15 °C trials (mean = 1.04 and 1.05, respectively) when averaged across salinity.
