Abstract
To overcome the environmental impacts of releasing oil into the ocean for testing acoustic
methods in field experiments using autonomous underwater vehicles (AUVs), environmentally
friendly gas bubble plumes with low rise velocities are proposed in this research to be used as proxies
for oil. An experiment was conducted to test the performance of a centrifugal-type microbubble generator in generating microbubble plumes and their practicability to be used in field experiments. Sizes
of bubbles were measured with a Laser In-Situ Scattering and Transmissometry sensor. Residence
time of bubble plumes was estimated by using a Ping360 sonar. Results from the experiment showed
that a larger number of small bubbles were found in deeper water as larger bubbles rose quickly to
the surface without staying in the water column. The residence time of the generated bubble plumes
at the depth of 0.5 m was estimated to be over 5 min. The microbubble generator is planned to be
applied in future field experiments, as it is effective in producing relatively long-endurance plumes
that can be used as potential proxies for oil plumes in field trials of AUVs for delineating oil spills.
