On Dive 16 of the expedition, scientists explored what is believed to be an old reef terrace edge north of Gardner Pinnacles. The objective of the dive was to survey the terrace edge, which is now a 200-meter high narrow ridge, for corals and sponges to gather information on whether high-density communities can be found on ridge topography.
