MIT software optimizes paths for automated undersea vehicles (video)

By Darren Murph posted Mar 12th 2012 4:39AM
So, there's good news and bad news. The former is that MIT researchers have developed new software and methods that can predict optimal paths for automated underwater vehicles. The latter is that it's meant to be used for "swarms" of them, "moving all at once toward.... http://www.engadget.com/2012/03/12/mit-software-optimizes-paths-for-automated-undersea-vehicles/

Sometimes the fastest pathway from point A to point B is not a straight line: for example, if you're underwater and contending with strong and shifting currents. But figuring out the best route in such settings is a monumentally complex problem — especially if you're trying to do it not just for one underwater vehicle, but for a swarm of them moving all at once toward separate destinations.

But that's just what a team of engineers at MIT has figured out how to do, in research results to be presented in May at the annual IEEE International Conference on Robotics and Automation. The team, led by Pierre Lermusiaux, the Doherty Associate Professor in Ocean Utilization, developed a mathematical procedure that can optimize path planning for automated underwater vehicles (AUVs), even in regions with complex shorelines and strong shifting currents. The system can provide paths optimized either for the shortest travel time or for the minimum use of energy, or to maximize the collection of data that is considered most important.

Collections of propelled AUVs and gliding AUVs (also called gliders) are now often used for mapping and oceanographic research, for military reconnaissance and harbor protection, or for deep-sea oil-well maintenance and emergency response. So far, fleets of up to 20 such AUVs have been deployed, but in the coming years far larger fleets could come into service, Lermusiaux says, making the computational task of planning optimal paths much more complex.

Crabbers get a boost in bairdi Tanner quotas

LAINE WELCH Image via Wikipedia FISHERIES Published: November 7th, 2009 10:10 PM Last Modified: November 7th, 2009 10:12 PM KODIAK -- Kodiak and Alaska Peninsula crabbers got some good news last week -- bigger catch quotas for bairdi Tanner crab, a mid-January fishery important to local economies. Bairdi are the larger cousins of the better-known opilio Tanners, or snow crab. The bairdi boost stems from a big pulse of new crab recruits that biologists have been tracking for years. "That is what's fueling the increase in the harvest this year. We're just getting the very beginning of that year class," said......... http://www.adn.com/money/welch/story/1004091.html

Danish commandos 'monitoring hippies' on Arctic offshore rig #artcticloons

Image by Steve Rhodes via Flickr Alaska Dispatch | May 31, 2011 Armed Danish commandos have (possibly) been summoned to monitor Earth-loving "hippies" clinging to the underbelly of an Arctic deepwater oil rig  off the coast of Greenland , sources say. The environmental non-governmental group  Greenpeace  has published  statements and  video  showing its activists aboard two ships that are attempting to "interfere" with oil exploration going on in the Davis Strait, 100 miles west of Greenland. This business has in turn prompted the Kingdom of Denmark to launch two ships and a few helicopters to monitor the Greenpeace interference. The  Leiv Eriksson  is the source of all this Arctic bait and switch. British oil company  Cairn Energy  is attempting to drill four wells at depths of at least 5,000 feet this summer in "iceberg-strewn sea" with the 53,000-ton offshore oil rig, which has made its way to Arctic waters after a month of failed attempts by Green
