Highlights from Dive 14 of the expedition, which was conducted on a ridge that extends northward from Pioneer Bank to determine whether ridge topography is suitable habitat for high-density communities of corals and sponges. The depth of this dive was closer to the oxygen minimum zone, so scientists were also interested in detecting any effects of a lower oxygen environment on the communities.
