a Geologic interpretations of Dives 652 (left) and 650 (right) on the 32° 35′ N and 32° 40′ S secondary detachment fault faces, respectively. b Dive 652 plan view showing high-angle normal fault face. Thick black lines are navigated dive tracks. c Dive 650 traverse up the north-facing secondary detachment footwall and the fault breakaway zone separating it from the primary detachment fault footwall at the north end of the Atlantis Bank gabbro massif. Profiles represent distance along track, rather than a straight line up a constant azimuth. Scientific divers H. Kumagai and M. Cheadle as indicated on the cross-sections
