DELAWARE — The recent publication of a paper co- authored by two marine scien- tists explains how autonomous underwater vehicles (AUVs) could be programmed to make independent decisions on what to do next while studying the ocean. The published paper,


according to a University of Delaware story, discusses the advantage of linking multi- sensor systems aboard an AUV to enable the vehicle to syn- thesize sound data in real-time so it could independently make decisions about what action to take next. The paper was recently published in Robotics and written by Mark Moline, direc-

British Team wind fourth event in America’s Cup World Series


MUSCAT, Oman (Log News Service) — Former Olympic star Ben Ainslie of Britain lead his Land Rover BAR team to victory in the fourth event of the America’s Cup World Series. Ainslie’s crew finished second,


third and fourth in Feb. 28’s races. It had two firsts and a third on Feb. 27. Emirates Team New Zealand finished third to retain its place atop the overall Louis Vuitton America’s Cup World Series


tor of the School of Marine Science and Policy in the University of Delaware’s College of Earth, Ocean, and Environment, and Kelly Benoit-Bird, a colleague at Oregon State University. The researchers used an


AUV for deep-sea research called REMUS 600 for the experiment. They pre-pro- grammed the AUV to react to certain movements in the ocean.


When acoustic sensors


aboard the vehicle detected the right size and concentra- tion of squid it triggered a sec- ond mission: to report the robot’s position in the water and then run a prepro- grammed grid to map the area


leaderboard with 192 points, although Oracle closed the gap to just 6 points. Ainslie sailed with Oracle dur- ing the 2013 America’s Cup, when the American-based team rallied to beat Emirates Team New Zealand. Feb. 27 marked the first


America’s Cup racing in the Middle East. In 2009 Oracle kept Alinghi of Switzerland from defending the America’s Cup in the United Arab Emirates by rais- ing the safety issue. Four more events are sched- uled in 2016 with the next two scheduled in the United States — New York, May 7-8, Chicago, June 11-12. The final two include Toulon, France Sept. 10-11 and a yet to be announced race, which is expected to be held in Asia in November.

in finer detail, according to the University of Delaware. The scan found a very con-


centrated group of squid in one area and a second less tightly woven group of similar- ly-sized squid in another area just south of the first group. Moline stated these details might have been missed if the REMUS was only programmed to keep traveling on a straight line instead of being able to switch missions and investi- gate the second group of squid. The researchers believe combining available robotics technologies to explore the water in this way can help fill information gaps and uncover new information.
