From bottom contact triggers to transmissometers, oceanographic sensor options are vast and diverse, and choosing the right combination of sensors can significantly augment a CTD’s measurement capabilities. Although getting disparate technologies to talk to one...
The data shows conductivity from a 19plus deployed in a shallow estuarine river. The red line shows the CTD downcast and the green line shows the upcast. While the upcast data show the expected shape for a CTD profile (low conductivity at the surface, rising conductivity as the CTD descends), the downcast shows an unusual shape in until about 2.6 meters depth, where conductivity appears to suddenly correct itself.
May 2020 Newsletter The data above show two major symptoms of the same problem occurring in different locations on a 19plusV2 profiling CTD. On the left, oxygen appears to drop below zero and is highly erratic during the downcast (light blue). However, once it hits a...
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...
These data show a subtle problem that is producing “fuzzy” salinity and oxygen data. While the overall shape of the profile appears reasonable, small spikes are present throughout the CTD cast. The black lines encompass a particularly strange spot where both salinity...
