Conductivity, Temperature and Depth (CTD) data from the SIPEX II voyage of the Aurora Australis
Multiple CTD (conductivity, temperature, depth) casts were deployed during the SIPEX II AAD Marine Science voyage in September-November 2012. The system uses a descending rosette capable of holding up to 24 CTD bottles. During this voyage the CTD rosette also housed two krill traps (using controllable lights) and two GoPro cameras contained in pressurised, waterproof containers that were used to monitor the krill traps and view objects both on the sea bed and in the water column.
Some functions of the GoPro cameras could be controlled from within the ship using the same transmission cable used by the CTD system. These functions included being able to change the focus setting of the cameras or start/stop recording. More information about the krill traps and cameras is contained in the SIPEX II Bottom Krill dataset.
When a bottle is 'fired' from the ship it briefly opens, draws in water samples and closes again. It is not reopened until it is brought on board the ship. Bottles are opened at different depths to obtain samples from these depths. The depths vary from cast to cast and so are recorded in the CTD Log sheets (contained in this dataset as PDF files).
Only raw data is contained in this dataset. The raw data was used by a variety of experiments during the SIPEX II voyage to produce results applicable to each experiment.
Thanks go to the P and O crew of the RV Aurora Australis for their assistance during CTD operations.

Resource lineage
- Statement
- Occasionally a bottle would not fire. It is thought that the camera communication was interfering with the CTD messages from the ship to the rosette. The workaround was to fire the bottle directly after a message was received form the camera, then confirm that it had fired before starting to write down the details of the fire on the CTD log sheet.
