First dive of the expedition starts at Niua South. The ROPOS ROV will be conducting a photogrammetric survey of the vent field.
Hydrothermal vents are like geysers, or hot springs, on the ocean floor. Along mid-ocean ridges where tectonic plates spread apart, magma rises and cools to form new crust and volcanic mountain chains. Seawater circulates deep in the ocean's crust and becomes super-heated by hot magma.
