Underwater robot provides first detailed, high-resolution 3D maps of Antarctic sea ice

By - November 25, 2014 6 Pictures
Antarctic scientists have combined measurements provided by an underwater robot with existing satellite data to show that Antarctic sea ice may be thicker than previously thought. Their first-of-a-kind high-resolution 3D maps cover over 500,000 square meters in the Weddell, Bellingshausen, and Wilkes Land sectors of Antarctica, and they reveal heavy deformation in all three near-coastal regions that produces mean sea-ice draft (thickness of the submerged part of the ice) far in excess of ice drilling and ship-based measurements. This is a big leap forward in our ability to understand why and how the ice is changing on both small and large scales. Read More

Submersible Exosuit lets divers plunge to 1,000 ft below the surface

By - October 13, 2014 6 Pictures
Thanks largely to Hollywood blockbuster franchises, humanity seems to be in the grips of a global obsession with exosuits. The fixation is informing the designs of future military tech and may even play a role in how we operate in space. Canadian based Nuytco Research hopes to bring its own Exosuit to the sea floor, allowing divers to safely operate at depths of up to 1,000 ft (305 m) with none of the nasty pressure-induced side effects that so often ruin a deep sea diver's day.

Hull-clinging robots could perform secret searches of smugglers' boats

By - September 26, 2014 1 Picture
Maritime smugglers will often hide contraband in false hulls or propeller shafts within their boats. While there are ways in which port authorities can search for such stashes, the smugglers often have time to ditch their illicit goods before those searches can be performed. However, what if there were stealthy, inexpensive, underwater hull-hugging robots that could check the boats out, without the crews even knowing they were there? That's just what a team at MIT is developing. Read More

DeepFlight Dragon set to usher in the era of the personal submarine

By - August 27, 2014 22 Pictures
No one with red blood in their veins buys a sports car and hands the keys to a chauffeur, so one of the barriers to truly personal submarining has long been the need for a trained pilot, not to mention the massive logistics involved in transporting, garaging and launching the underwater craft ... until now. Pioneering underwater aviation company DeepFlight is set to show an entirely new type of personal submarine at the 2014 Monaco Yacht Show next week, launching the personal submarine era with a submersible that's reportedly so easy to pilot that it's likely to create a new niche in the tourism and rental market.
