Full Validation and Clean 11/Jan/2012

After many weeks of high winds we finally completed a full station cleanup of all instruments, chains, lines and pole on Wednesday 11th January 2012. Surprisingly the biofouling was not as much as we suspected, but definitely needed a clean. Could this be due to Herbivory fish?

The GT was installed at 7:45 am. Cleaning commenced around 10:40, (we installed some settlement plates on the reef wall before we started cleaning), and finished around 12:05, the GT sensor was then removed around 3:30. In addition to the general cleaning of the station and instruments we replaced the copper filters on the CTD and added three anodes to three separate chains, more will need to be replaced over the coming months. The condition of the lines are in good shape, the four lines at the base did not seam as tight as normal but the station was solid and the orientation has not changed.
