Today, 24 March 2011, a full cleaning and validation was completed. Rough weather has not allowed us to to get out to the station for a week. The validation CT was plugged in at 9am. Cleaning was initiated by 2 divers at 10:25 and lasted for one hour. All spectra lines, chains, and cables were inspected and confirmed to be in good working order. Copper screens were cleaned, but in good condition. There was light to moderate fouling of the pylon from algae build-up. The CT was then removed at 2:00. The pylon itself seams to be in good shape but standing with a slight tilt and twist to the north, no change though.
On Wednesday 2 March 2011, after having problems with transmitting data from the CTD to the CREWS computer at LCRC, we decided to swap out the CT cable with the CTD cable to test both the cables and instruments. The system came online before we switched these cables but were unaware.
We swapped out the CTD cable with the CT cable in the brain and then the again the instrument end. After turning the system everything again came back online, no damage had seamed to be done completing this swap out. The cables are still switched on the station. All chains and instruments were then cleaned, inspected and left to do their job.
