Dive 15: Final Dive

The vehicles are in the water for the final dive of the Laulima O Ka Moana expedition. Today’s dive is on an unnamed seamount that abuts the southeast edge of the Johnston Atoll Unit. The onboard team mapped the seamount for the first time last night and selected a dive site early this morning. This dive will climb a volcanic cone on top of the guyot starting at ~2,050 meters (~6,725 feet) and will reach the summit at ~1,810 meters (~5,940 feet). The goals are to document seafloor communities, search for deep sea coral and sponge communities, and collect rocks for age dating and geochemical analysis.
