Principal discoveries made during the expedition were a natural bridge cave at 215 ft. depth on the northern edge of the main Bermuda platform, a drowned reef at nearly the same depth off the south shore, a sea level notch at 370 ft. at the eastern edge, and regularly spaced vertical rifts and jagged, possibly volcanic, cliffs along the southeastern side of Challenger Bank at depths to nearly 450 ft. All of these features were formed during the Ice Ages when world sea level had retreated to the depths that we reached on these dives. The goal of the “Bermuda Deep Water Caves 2011: Dives of Discovery” expedition is to explore and characterize the upper edge of the Bermuda Platform and an adjacent mid-ocean seamount to confirm the existence of deep-water (60-200 meter/197-656 foot depth) caves. The initial two phases of this project were conducted in 2009. First, in collaboration with Dr. Rikk Kvitek of California State University’s Seafloor Mapping Lab, high resolution multibeam sonar was used to produce detailed, geo-referenced maps of the shelf edge of the Bermuda Platform and adjacent Challenger Bank.
