A cross-plot of the matched observations over the entire deployment is given in figure 3.
Comparisons were limited to one month as a representation of a typical field deployment and to focus
on initial instrument offset versus impacts of biofouling during an extended deployment. A linear
regression of the data (r2 = 0.99) produced a slope of 1.053 and intercept of -0.491.
