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

Underwater gas bubbles acoustic monitoring and seabed mapping around Whakaari Island

Dr Yoann Ladroit, Whakaari TAN2007 Voyage

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.
