Technical Consultant Bob Ballard’s ending comments:
Hello, I’m Bob Ballard from the Woods Hole Oceanic Institution. Sink holes are very common in the ocean’s floor off Florida. A large one was recently discovered near Tampa Bay. In fact, our submersible, Alvin, came across one in fifteen hundred feet of water, south of the Florida Keys. The sub dropped down inside the sink hole several hundred feet before returning safely to the surface. See you on the next exciting adventure of seaQuest DSV.
