Dive Notes:

Mapping team of Connie, Charlie, and Dave led team from the Amarylis to the site. Again there was a thermocline on descent at approximatley 25 feet. Temp in upper water column was 70' and 66' at depth. All divers commented it was cold at the bottom. Mapping team again found all benchmarks and cleaned them off, including the marker for Greg Thompson. Mapping team then surveyed site for any significant changes to reef profile. No changes were noted and the mappers moved over to Murphy's Barge to note its condition. We saw a 3.5 foot long Goliath Grouper on the southeast corner of the barge.
