The world's first underwater nightclub

Of all the places you might meet a significant other, underwater is probably the last place that springs to mind. Hence, I guess, the novelty of an underwater nightclub. Created as a viral campaign for TechnoMarine Underwater watches, the unique nightclub "launch" was filmed at a military training facility with navy divers and the set was built 14 feet (4 m) underwater. The breathing helmets are from the commercially-available Sea Trek system, so perhaps it's not all that implausible after all. Read More

NASA heads underwater to test concepts for future asteroid mission

With the first manned mission to an asteroid planned for 2025, NASA has sent an international group of “aquanauts” to the ocean floor off the Florida coast to test concepts for such a mission. The four-person crew will spend 12 days 63 feet (19 m) below the surface of the Atlantic Ocean in the Aquarius lab located in the Florida Keys National Marine Sanctuary as part of the 16th excursion of the NASA Extreme Environment Mission Operations (NEEMO) program.

Special solar cells produce electricity from underwater sunlight

Although solar cells are proving indispensable for powering things such as electronic sensors on dry land, sensors located underwater have typically had to rely on batteries, or electricity piped in from photovoltaic panels situated above the surface. That could be changing, however, as scientists from the U.S. Naval Research Laboratory have recently developed functioning underwater solar cells. Read More

OpenROV could open up the world of underwater exploration

Underwater remote-operated vehicles, or ROVs, are almost impossibly fascinating. They’re controlled by a surface-based operator, who watches their real-time video feed and pilots them via a long umbilical cable. Although the big-league multi-million-dollar ROVs are used for things such as exploring the wreck of the Titanic or studying hydrothermal vents, hobbyists have quite a bit of fun using their own home-built versions just to see what’s under the surface of the local lake. Unfortunately, even to build one yourself, you need to be pretty technically skilled. That could change, however, as the OpenROV project is developing “easy to assemble” kits – it may even provide li’l ROVs that are ready to go, right out of the box. Read More

Architects transform submarine into a bar

Two hundred and fifty years ago, brewer Arthur Guinness signed a 9,000-year lease for his St. James's Gate Brewery in Dublin, Ireland. To commemorate this event, the Guinness company could have rolled out a stretch limousine, but it decided to go one better by launching a “deep-sea bar” in the chilly waters of the Baltic off Stockholm, Sweden. Designed by London-based Jump Studios, the modified tourist submarine was commissioned as part of the Guinness Sea Experience competition, that included an underwater trip inside the Guinness sub as a prize.

"Dolphin speaker" could pave the way for human-cetacean communication

While there’s little doubt that dolphins are saying something to one another with all their clicks, squeals and whistles, we’re still not entirely sure just what it is that they’re communicating. We may be getting closer to figuring it out, however, as Japanese scientists have created an underwater speaker that’s capable of playing back the creatures’ entire acoustic range. The next step - see how they respond. Read More
