The aim of the TAN1806-QUOI voyage (Quantitative Ocean-Column Imaging using hydroacoustic sources) conducted from RV Tangaroa was to enhance our capability to acoustically detect and characterise liquid and gaseous targets in the ocean water column.
The voyage took place between 3 and 22 July 2018. The science party consisted of 20 scientists and students from the consortium organisations as well as students from the University of Auckland, the University of Tasmania, the University of New Hampshire and the Ecole Nationale Supérieure des Technologies Avancées.
The 20-day voyage covered ca. 3640 km (1970 NM) from Wellington to the Bay of Plenty and back to Wellington (figure 1). The large part of the voyage took place in the Bay of Plenty with 13 days spent over the Calypso Hydrothermal Vent Field, ca. 15 km SW of Whakaari-White Island volcano. Numerous hydrothermal vents have been identified in the past over the region through acoustic flares and visual observation and the location therefore provided an excellent opportunity to develop our experiments.
