Coral-repairing robots take a step closer to reality

By - April 16, 2013 2 Pictures
Since humans are responsible for much of the damage to coral reefs, it makes sense that we should try and help repair them. That’s exactly what a team from the Herriot-Watt University’s Centre for Marine Biodiversity and Biotechnology is attempting to do with the development of underwater “coralbots,” which we covered last year. Now anyone can add their support to this worthy effort with the launch of a Kickstarter campaign that will help make the robots a reality. Read More

Students set sights on human-powered submarine speed record

By - April 4, 2013 6 Pictures
Students at the University of Warwick have announced their intention to build a human-powered submarine to compete at that highlight of the human-powered submarine events calendar, the European International Submarine Races in 2014. The team of engineering students hopes that their vessel, already named HPS Shakespeare, will beat the current speed record for a single-seat human-powered sub. Read More

Big O brings LCD viewfinder window to Outex DSLR housing system

By - March 14, 2013 7 Pictures
While DSLRs give photographers great creative freedom and image quality, the cameras themselves don't cope too well with being exposed to excessive amounts of sand, mud, water or snow – which can be a pain if you get your kicks from shooting things like extreme sports. Outex is a weather and modular waterproof housing system for DSLRs that works much like a drysuit for your camera, and can protect your gear underwater to a depth of 10 meters (33 feet). The new "Big O" adds a big Outex LCD viewfinder window to the system. Read More

DARPA wants to hide naval assets on the sea bottom

By - January 14, 2013 2 Pictures
The Defense Advanced Research Projects Agency (DARPA) has seen the future of naval warfare and it’s falling upward. As part of an effort to reduce the logistics of sending equipment into trouble areas, the agency’s Upward Falling Payloads project is aimed at developing storage capsules capable of remaining on the deep seabed for years. These would contain non-lethal military assets that could be deployed on the spot years in advance and rise to the surface as needed. Read More

Autonomous marine robots used to detect and identify endangered whales

By - January 9, 2013 3 Pictures
Every year between November and January, endangered North Atlantic right whales are thought to use an area off the coast of Maine known as the Outer Fall as a breeding ground. They are “thought to” because the ocean conditions at that time of year can make it difficult to locate them. Two autonomous marine robots called gliders have now been used as a real time whale-detection system for researchers and to warn boats in the area to slow down to avoid striking the marine mammals.

Blind cave fish inspires sensing system for autonomous underwater vehicles

By - December 13, 2012 3 Pictures
Ever wonder how fish can find their way around so easily in murky water? Well, most of them use something called their lateral line – a row of hair cells down either side of their body that detect changes in water pressure caused by movement, or by water flowing around objects. Now, scientists from Singapore’s Nanyang Technological University and MIT have copied the lateral lines of the blind cave fish, in a man-made system designed to allow autonomous underwater vehicles (AUVs) to navigate more accurately and efficiently.

Poseidon Resorts completes underwater hotel design

By - November 28, 2012 10 Pictures
The buzz around Poseidon Undersea Resorts has been around for a few years now (c.f. our 2007 report on the conceptually-similar Hydropolis in Dubai). Poseidon Resorts has announced that it has completed the design and engineering of structural works, indicating that the sci fi-esque undersea project is closer to getting off the ground, or better, into a lagoon on a private island in Fiji. The company is now working to secure capital for construction, which should take two years to complete, it says. Read More
