NIWA and The Nippon Foundation are undertaking a mission to discover the undersea impacts of the recent Tongan volcanic eruption. In a rare opportunity to improve understanding of the nature and impact of a major volcanic eruption, NIWA scientists are sailing to Tonga to survey the ocean around the Hunga-Tonga Hunga-Ha'apai (HT–HH) volcano and surrounding regions. They will be surveying thousands of square kilometres of the seafloor and collecting video images of the eruption’s impact from NIWA’s research vessel, RV Tangaroa, and using SEA-KIT International’s Uncrewed Surface Vessel (USV) Maxlimer to conduct further mapping.
