HTTP:: Seaglider Sets New Endurance Record
--------
Spending nine months and five days in the deep sea seems like something even a top-class submarine would find difficult to accomplish without maintenance work. But this proved to be a walk in the park for a University of Washington Seaglider, which spent this entire time on a single mission, roaming the Pacific Ocean, and submerging to great depths to collect scientific data. It roamed in total more than 3,050 miles (4,900 kilometers) in the North Pacific, a distance equivalent to crossing the Atlantic from England to the US. This achievement sets a new record for this type of craft and mission.The ship's controllers say that no other underwater robotic exploration vehicles managed to stay on course within the parameters of such a mission, not even for half of the time the Seaglider did. The newly established record is absolute both in terms of the amount of time spent under the water, and of the total distance that the craft traveled under its own propulsion system (that i!
s to say, unaided by currents).“Operating endurance is about how far a glider propels itself â€" as opposed to drifting with currents â€" and how often dives are made to collect oceanographic data. And the Seaglider was truly autonomous the entire time,” UW Professor of Oceanography Charles Eriks...
