The submersible vessel Pisces V surfaces in the foreground after a dive in front of Macauley Island during a 2005 New Zealand-American NOAA Ocean Explorer research expedition to the Kermadec Arc. This view from the NW shows a prominent white band in the cliff face that is made of dacite pyroclastic flow deposits. The 3-km-wide Macauley Island is a remnant of the rim of a large submarine caldera centered 8 km to the NW and has a low, gently sloping surface truncated by steep cliffs.
