Last November, Liquid Robotics let loose four Wave Gliders in the Pacific ocean. The autonomous robots -- outfitted with sensors that measure and collect information on a variety of substances, from oil spills to salinity levels to weather information -- are wave-powered, using the rolling motion of the water to propel forward. It's a slow, slow journey traveling at about 1.5 knots, but one Wave Glider, named "Papa Mau", has completed the 9,000 nautical mile trip across the Pacific, leaving a world record for longest autonomous trip in its wake.
This link between new ways of sensing and modeling information about the ocean is the goal of Liquid Robotics -- to provide real-time information about the ocean on a vast array of issues. Papa Mau may have set a record for distance, but these Wave Gliders are doing much more than that. They are proving to be an important new technology for understanding the state of our oceans.
"We’ve demonstrated delivery of ocean data services through the most challenging ocean conditions. Mission accomplished,” said Bill Vass, CEO of Liquid Robotics.
As Fast Company notes, "The Wave Glider is currently being used for up to 60 different applications, including helping ships reduce fuel consumption, measuring carbon output, helping wit fishery management, and oil and gas exploration... [T]he Wave Glider can detect oil spills in remote places where they might otherwise have gone unnoticed for too long. With so many capabilities, it’s no surprise that Wave Gliders are used by organizations as varied as BP and NOAA."
The next Wave Glider expected to surf in from the ocean in early 2013 is "Benjamin." You can watch the progress of the other gliders here. And here is a short documentary on the occasion of Papa Mau's arrival in Australia:
