MG111 Natural Reef
Physical Data
and Notes

June 5, 2004

Dive Notes:

Current was moderately strong, especially at the surface. There was a thermocline at 30 ft with surface temp at 78'F and 75'F at the bottom. Map team finds benchmark stakes at 1,2& 3 and clean them off and then take GPS readings of their location. Map team didn't find #4, but other team members did. The stake was laying on the substrate having come out of the ground. Better reef relief is to north of the area of our benchmarks. Map team didn't see much of interest on this dive.
