Although they should match perfectly, the two sensors rarely reported the same temperature value throughout their deployment. Furthermore, the 16plusV2 appeared to stop logging, although the batteries still had life upon recovery. Can you identify the problem?

Q&A: Erratic Profiles
November 2019 Newsletter The data above come from a profiling CTD, deployed in sea conditions that caused approximately 1-meter ship heave. Two things stick out – relatively unchanging salinity data during the downcast, and noisy data during the upcast (shown in light...
Q&A: What is Causing the Difference between Internal and External pH?
The figure above originates from a single Shallow SeaFET V2 pH sensor, which produces two pH values (Internal pH and External pH) from two separate reference sensors. The black X’s indicate pH validation samples. While environmental conditions affect each the...
