On November 17th, 2011, in San Francisco, Liquid Robotics launched four Wave Gliders that will travel the longest distance at sea ever completed by an unmanned marine vehicle. The robots will travel together to Hawaii and then take separate routes across the Pacific, one pair arriving in Japan and the other in Australia. While at sea, the Wave Gliders will be routed across regions never before remotely surveyed and will continuously transmit valuable data on salinity and water temperature, waves, weather, fluorescence, and dissolved oxygen. Each Wave Glider is equipped with a Turner Designs C3 Submersible Fluorometer with 3 sensors: crude oil, chlorophyll, and turbidity.
