James Clarke Ross Cruise AMT14 CTD Instrumentation
The CTD unit was a Sea-Bird Electronics 911 plus system, with dissolved oxygen sensor. The CTD was fitted with a transmissometer, a fluorometer, down and up welling PAR sensors. All instruments were attached to a Sea-Bird SBE 32 carousel. The table below lists more detailed information about the various sensors.
