Oceanographers select Wave Glider ocean robot for scientific research

Top oceanographers have selected Wave Gliders, the most experienced, long duration ocean robots, as their sensor platform to conduct advanced scientific research in the most inhospitable and remote regions of the Arctic and Southern Oceans.

The US scientists, from Scripps Institution of Oceanography (Scripps) and the Applied Physics Laboratory of the University of Washington (APL-UW), will integrate sophisticated oceanographic and atmospheric sensors onto the Wave Gliders to measure extreme wave states, winds, temperature, and salinity in the upper layers of the ocean.

Historically, these regions have been under-sampled due to the dangers and risks of operating in these turbulent oceans.

Using Liquid Robotics Wave Gliders, proven in extreme ocean conditions (sea state 6+), scientists will obtain real time data and rare insights into the dynamic conditions that drive the world’s weather and climate.

With the help of unmanned systems, the oceanographers will be able to observe the real time weather and climate conditions safely from shore.

This data is critical for scientists to understand and improve global ocean weather modelling and climate prediction.

The oceanographers leading these missions are: Dr. Eric Terrill and Dr. Sophia Merrifield – Coastal Observing Research and Development Center, Scripps ; Dr. Ken Melville and his team at the Air-Sea Interaction Laboratory, Scripps; and Dr. Jim Thomson and his team in the Stratified Ocean Dynamics of the Arctic (SODA) program at APL-UW.

“The reliability of the platform, modular payloads, and proven navigation capabilities led to our decision to select the Wave Glider for our upcoming science program,” stated Dr. Terrill, Director of the Coastal Observing R&D Center at Scripps.

“Tackling at-sea science questions has plenty of challenges and we needed a platform we could trust and adapt. The modularity allows us to deploy our own sensors and adapt autonomy algorithms so that the vehicle will optimally sample the ocean.”

Working together with Liquid Robotics, these top oceanographers have successfully conducted long duration scientific missions in the Arctic, Pacific, Southern and the North Atlantic oceans. Deploying Wave Gliders in the most energetic sea conditions on Earth will help scientists gain a better understanding and modelling of the changing planet.

“In 2016, we successfully completed a 3 month, 2000km mission in the Southern Ocean where the Wave Glider performed through 6m high waves, extreme winds, and swam through the world’s largest ocean current, the Antarctic Circumpolar Current,” said Dr. Jim Thomson, Senior Principal Oceanographer at APL-UW.

“The data collected provided unprecedented temporal and spatial coverage and I have great confidence our upcoming Arctic mission in the Beaufort Sea, part of the Stratified Ocean Dynamics of the Arctic, will again provide valuable insights.”
