Can sound be used to characterise gas composition in the water column?

NIWA Marine Acoustician Dr Yoann Ladroit uses multi-beam echo sounders to map the bathymetry around Whakaari/White Island very quickly and with pinpoint precision.

Yoann is also leading research into using acoustics to find underwater gas bubble flares and then compare these to the chemical composition of water samples taken at the same locations.
