On 7/25 Jon Fajans and Adam Harrison performed a basic cleaning of CMRC 3.
Macro growth was removed from all lines and chains. CTD screens were checked and are ok. All zincs were checked. The missing zinc on the shallow CTD was replaced. The loose zinc on one mooring chain has corroded itself back into place and is secure. It was decided that we would leave that zinc in place until it completely wares out.
Jon Fajans checked the immediate area for signs of coral bleaching and found none.
Next scheduled cleaning is on or about 8/4 and is a full cleaning/groundtruthing.
Many apologies for the delay in posting this.

CMRC3 full cleaning/groundtruthing 7/7/07
On the morning of 7/7/07 Madeline Weigner and Adam Harrison performed a full cleaning of CMRC3 including CT validation.
The CT validation unit was installed just after 6:30. Cleaning commenced at 8:15. The CT Validation unit was removed at 10:25.
All lines, cables, chains, anodes, and sensors were cleaned and are in good condition. The zincs are in similar condition to what was last reported 2 weeks ago. The zinc that was loose on the chain is no longer loose due to buildup of corrosion. It still is deteriorating and will need to be replaced in the near future.
I still have not received a replacement zinc for the shallow CTD.
There was very little biofouling inside either CTD.
There is some evidence of coral bleaching around the stick, however, most coral growth is looking very healthy.
Madeline noted on her recent dives at the NE Norman's site (adjacent to CMRC3) that there is evidence of recent coral bleaching. She's been diving that site almost daily and recognized increased bleaching this past week.
Next scheduled basic cleaning is on or about 7/20.
Ciao,
