Buoy maintenance Monday 12/07/10

Some pictures of our routine maintenance trip to the L4 buoy on Monday 12th July. We found large amounts of bio-fouling on the instrument cage. After a clean and a quick check of the functionality of all the sensors the cage was returned to the moon pool in the buoy and only missed one data acquisition.
Also we re-fitted the AIS system on the L4 buoy after urgent updates had been installed. Both buoys are now reporting full AIS information as well as all scientific parameters.
