Hey there. Has anyone else noticed that the Gen2 CTD sensors seem to produce noisier conductivity data than the Gen1? I haven’t done any analysis to back this up have observed seemingly more anomalous conductivity values at sites where I’ve deployed this sensor. I can provide some examples if helpful. Generally I’m seeing drops of 50-150 us/cm between our 15 minute measurement increments, sometimes this is just for one measurement while at other times it’ll maintain this lower conductivity level for an hour or more, before jumping back to “normal” conductivity. Just thought I’d see if anyone else has noticed something similar before investigating further.
