Alternative Labels SBE 911 CTD
Definition High precision and accuracy CTD made up from a Sea-Bird SBE 9 underwater unit and a SBE 11 deck unit. The underwater unit comprises protective cage (usually with a rosette) holding a pressure unit and temperature/conductivity unit. The latter is connected to a pump-fed plastic tubing circuit that may include other sensors. All plumbed and non-plumbed instruments (e.g. transmissometers and light meters) on the package are logged by the SBE 11. The unit was replaced by the SBE 911plus in 1997.
