Low outcrops of flat, massive rocks poked up through the sediment. Sponges

In the laboratory this evening, we examined
some of the massive flat rocks we recovered during the second dive today.
Testing the rock with dilute phosphoric acid showed that they are
comprised of calcium carbonate. The appearance of these rocks is similar
to those known to have been formed from methane-derived authigenic
carbonate. Further study will be required, but this was a pleasant
surprise.

All exterior doors on ships have two dogs (the upper one is shown in this photo).
