Q&A: Diagnose This Profile

Q&A: Diagnose This Profile

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.
