Propelled by wave motion, the Wave Glider SV3 travels the oceans, collecting sea data used for science, education, surveillance, and defense. In a recent Pacific Ocean crossing, four of these autonomous gliders travelled a combined 34,000 miles and collected 2.25 million discrete data points. More than 150 gliders are currently at sea. At the Esri UC, one of the gliders was docked in the Environment Showcase.
When the glider is in use, data is transmitted to an onshore office and added to an enormous database. With GIS, you can map Wave Glider sensor data such as salinity, water temperature, waves, weather, fluorescence, and dissolved oxygen. A combination of wave motion, onboard sensors, and solar energy all power the vessel.
