GPS track of the Sea Glider

Google Earth image of the glider track in white from deployment to recovery. Glider tracks can look like "Mr Squiggle" drawings. This is because the gliders are propelled only by a buoyancy engine and their movement can be overpowered by strong ocean currents. In the latter part of the mission, the glider returned to the hotspot area where it did multiple dives before it was recovered.
