The aim of the voyage was to enhance our capability to acoustically detect and characterise liquid and gaseous targets in the water column.
This 21-day voyage of R.V. Tangaroa studied the fate of gas bubbles in the water column using hydroacoustics and acquired multifrequency, multiresolution acoustic data and ground truthing data (video, samples) over the Calypso hydrothermal vent field in the Bay of Plenty, ca. 15 km SW of Whakaari-White Island volcano where numerous hydrothermal vents occur.
