Full Validation and Clean 13 June 2012 and Nav light replacement

After the Ground Truth sensor was installed at 7:50, a cleaning session involving 7 divers started at 9:00.  All the instruments, chains, lines and pole were cleaned.  Bio-fouling was moderate, probably due to us cleaning a the station a couple of weeks late.  Cleaning finished at 11:30 and the GT Sensor removed at 2pm.

We tried to replace the anodes on the chain but between the two sizes we have, one is two big and another two small. We will source from somewhere else.  Three of the chains do now have new anodes.  Anodes and filters on the instruments were also cleaned and checked and are in good condition.  While we were out there we mounted a YSI pH instrument to the side of the pole one meter below the surface.  This will be collected in 2 weeks and the data used for one of CCMI's Ocean Acidification Manipulative studies.

A few weeks ago the Navigation Light on the Station stopped working, yesterday (June 14th) we replaced the light with a Carmanah M650, a newer model of the M601 which was installed before. ( please see photo)
