We awoke in the Florida Middle Grounds, an area protected against bottom trawling formed by an ancient reef about 100 miles from the coast. Its peaks reach a depth of 25 meters. There we had planned to do another series of submersions. Our initial plan was to use the divers on the reef’s peaks and the ROV on the slopes that dropped off to depths lying outside the scuba’s possibilities. The submarine robot’s problems, that we hope to solve tomorrow, have forced us to concentrate on the shallower parts of the Middle Grounds. For the first time, visibility was excellent. The sandy bottom, sprinkled with coral, also held abundant specimens of coral and tube sponges in which specimens of gobies, spider crabs, grouper, hogfish, angelfish, jellyfish and algae like the halimeda live.
