Starboard profile of Alvin that is returning to service after a three-year overhaul

The National Science Foundation (NSF) announced on Friday that the Alvin deep-sea submersible is returning to service. The DC3 of the oceanographic world was launched fifty years ago in 1964 and is ready to begin its second half-century of service after a three-year overhaul involving significant redesigns and upgrades.  Read More

Using the Easybreath snorkel promises to feel more natural than traditional snorkeling

For those people unprepared to learn to scuba dive, snorkeling is a great way to explore the water while remaining close to the surface. The main problem with it is that it forces the swimmer to breathe through only their mouth, which can feel unnatural. Tribord's new Easybreath mask aims to solve that problem, by allowing natural breathing through the nose or mouth.  Read More

The Ovision underwater housing for iPhones 4 thru 5C

If you want to snap some pics with your iPhone while snorkeling or scuba diving, there are already a number of polycarbonate underwater housings that will let you take your phone to a depth of 30 meters (100 ft) or so. A few others can protect it down to around 57 m (187 ft). According to Montreal-based product designer Pierre-Yves Pépin, however, his Ovision housing is good to at least 91 m (300 ft).  Read More

Who wouldn't like to fly around underwater? You can already sort of do so using devices such as the SeaBob, although you're still basically just "along for the ride." If SCP Marine Innovations' Underwater Jet Pack reaches production, however, it looks like it should provide an experience much closer to that of being Aquaman.  Read More

The final design of the Platypus underwater exploration vehicle

After four years of development and months of prototype testing, Platypus founder Francois Alexandre Bertrand and his team have decided on the final design for their Platypus underwater exploration vehicle that will be launched next year. Aside from sporting a more polished look, the final production version also includes a number of newly-announced features.  Read More

When was the last time you heard about a sea turtle getting stuck in a shipwreck? Never, that's when. Although that's partly because stuck turtles rarely make the news, it's also due to the fact that they're relatively small and highly maneuverable. With that in mind, the European Union-funded ARROWS project has created U-CAT – a prototype robotic sunken-ship-exploring sea turtle.  Read More

The Manta Resort recently unveiled its Underwater Room (Photo: Jesper Anhede)

Underwater accommodations seem to have become a trend among hotels in recent years, but a resort off the coast of Tanzania is now putting a unique spin on the concept. The Manta Resort recently unveiled its Underwater Room, a three-floor suite that floats beside a thriving coral reef and boasts a submerged master bedroom surrounded by windows to view the local sea life.  Read More

The Platypus prototype takes passengers beneath the waves

Vehicles such as the EGO semi-submarine boat and Adventure-Doo are designed to bring the underwater action within reach of those without the time or inclination to put in the training required to get behind the controls of personal submarines like the offerings from U-boat Worx. But the Platypus underwater exploration vehicle from François-Alexandre Bertrand ditches the waterproof hull while giving users a taste of life beneath the waves. We first looked at the Platypus in concept form in 2011 and a prototype has now hit the water as it navigates the often-treacherous waters to commercial availability.  Read More

The Zayak provides a look at fish, plants and other sea life

Looking like a cross between a raft and a massage table, the Zayak Sea Sled is a new snorkeling alternative. It opens up the same type of underwater views, only without the need to submerge your face and breathe through a tube. You can explore the sea without getting a single strand of hair wet.  Read More

Dolphins' ability to tell the difference between fish and bubbles has inspired the creatio...

Chances are, you know that dolphins use sonar to locate and stun prey underwater. You might also know that they create "bubble nets," in which they trap fish inside a ring of air bubbles that they blow while swimming in a circle. With all those distracting bubbles suspended in the water, though, their sonar needs to work in a special way in order to pick out the fish. Scientists have copied that sonar system, to create a type of radar that could differentiate between ordinary objects and things like explosive devices.  Read More
