We have at least three targets in the northern Matas which are named consecutively from south to north by their Tongan “number” name, i.e., Mata Taha (one), Mata Ua (two), etc. To date we have identified at least 5 active hydrothermal systems on these small volcanoes using a towed CTDO and camera systems. Seafloor images of active vents, biology and hydrothermal deposits have been taken on three of them (Mata Ua, Mata Tolu and Mata Fitu).
