During the TAN2007 voyage NIWA scientists headed to the waters around Whakaari/White Island in the Bay of Plenty to survey changes to the seafloor since the volcanic eruption in December 2019. They also surveyed the chemical composition of gases released by the hydrothermal vents on what is known as the Calypso vent field in the Bay of Plenty.
The voyage commenced 22 July and ended 30 July 2020.
