Assessing the Impacts of Climate Change on the Great Barrier Reef with a WAM-V ASV

The Australian Institute of Marine Science (AIMS), in partnership with Queensland University of Technology, utilized a WAM-V Autonomous Surface Vehicle (ASV) manufactured by Marine Advanced Robotics to conduct an acoustic and optical survey of John Brewer Reef in the Great Barrier Reef system of North-Eastern Australia.

The goal of the project was to evaluate the use of Autonomous Surface Vehicles for reef health assessments. Specifically, the ability to autonomously complete shallow water bathymetric surveys and conduct optical surveys utilizing AIMS’ machine vision camera system (Reefscan). The WAM-V ASV was launched and recovered from AIMS’ Research Vessel (RV) Cape Ferguson. The WAM-V ASV enabled shallow water surveys and close approaches to sensitive areas.

The ability to collect useful data in the deeper water sections of the reef as well as across the reef flat was a welcome benefit of the WAM-V ASV platform. All Reefscan data was timestamped and georeferenced with the data then analyzed using Machine Learning models to give percent cover of the main benthic communities.

“The work that AIMS does is absolutely critical to understanding the impacts of climate change on critical habitats like the Great Barrier Reef,” said Mark Gundersen, President & CEO of Marine Advanced Robotics, “we are proud that the WAM-V technology was able to provide new capabilities in this ongoing effort and we look forward to future campaigns of this important combination of cutting-edge technologies.”

Marine Advanced Robotics is a San Francisco Bay Area based marine robotics company with an innovative class of watercraft based on their patented WAM-V technology. The WAM-V vessel class is the leader in stability, portability, and efficiency. WAM-Vs can be found all over the world performing critical tasks in the maritime environment.
