Kyocera is continuing with its mission to make tough (often affordable) phones. The company's latest rugged device is the Torque G02, which Kyocera claims is the first sea water-resistant smartphone.

A team of MIT researchers has developed algorithms that allow robots to plan and execute underwater missions with minimal human input. The technology should free up valuable time for project engineers, and may even open the door to autonomous exploration of remote parts of the planet's oceans.

Until the 1960s, Japan's three I-400-class subs were the largest submarines ever built. They were so large, in fact, that they could each carry and launch three Aichi M6A Seiran amphibious aircraft. The idea was that the submarines could stealthily bring the planes to within striking distance of US coastal cities, where they could then take off and conduct bombing runs. Now, for the first time since it was scuttled at the end of World War II, one of the sunken subs' aircraft hangars has been photographed. Read More
Developer Kleindienst Group is planning to construct 42 floating properties as part of the Heart of Europe development in Dubai. Technically classified as a boat, the Floating Seahorse offers an entire floor of submerged living, providing clear views of marine life beneath the gentle waves of the Persian Gulf. Read More
If you hunt unexploded sea mines for a living, then you might not mind losing your job to a robot. That seems to be the reasoning of the British and French governments, as they embark on a joint venture to develop a prototype autonomous system for detecting and neutralizing sea mines and UnderWater Improvised Explosive Devices (UWIED).

Deep sea diving is more than just slapping on an air tank and jumping in the water. It's a complex operation where the diver is the sharp end of a long, complex logistical train. It's also incredibly wasteful when it comes to the helium/oxygen gas mixture that the divers breathe, so US Navy scientists at the Naval Surface Warfare Center Panama City have developed a new prototype deep-diving system that goes easy on the helium.

When people are attempting to clean up oil spills at sea, one of the key things they need to know is the amount of oil that's been spilled – among other things, this will determine the amount of dispersant or other agents that are used. In order to make that process easier and more accurate, scientists from the Virginia Institute of Marine Science have developed a remotely operated vehicle (ROV) that does the job by measuring the thickness of oil slicks from below the surface.

A new MIT study has examined the possibility of acoustic-gravity waves – high-speed sound waves often generated by underwater earthquakes and landslides – acting as an early warning of tsunamis and rogue waves. Read More
When you inflate a balloon and then release it without tying the valve shut, it certainly shoots away quickly. Octopi utilize the same basic principle, although they suck in and then rapidly expel water. An international team of scientists have now replicated that system in a soft-bodied miniature underwater vehicle, which could pave the way for very quickly-accelerating full-size submersibles.

Early every spring in Antarctica, mats of algae form on the underside of the sea ice. These mats – along with bacteria that live in them – serve as a food source for zooplankton, essentially kickstarting the food chain for the year. Given that the ice algae plays such an important ecological role, scientists from Denmark's Aarhus University have set out to better understand its distribution. In order to do so, they're using a high-tech underwater drone. Read More
