August 18, 2004: The previous evening's multi-beam mapping revealed an interesting structure on the adjacent Ely Seamount: a volcanic crater on the summit. The P.I.'s decide to dedicate the last dive of the cruise tomorrow to exploring this structure.

There's bound to be something of interest for both the geologists and the biologists on this unique seamount feature. The crater is sensationally dubbed "the Caldera of Doom". Why? Probably because we watched Indiana Jones on DVD the night before.
