New system "works with the ocean" to plan best routes for autonomous subs

By - March 9, 2012 4 Pictures
Autonomous underwater vehicles, better known as AUVs, are increasingly finding use in applications such as oceanographic research, mapping, military reconnaissance, and deep-sea oil-well maintenance. As these independent underwater robots make their way through the world’s oceans, they use GPS transceivers to keep themselves on a predetermined route. When they encounter challenges such as cross-currents, one might assume that their best course of action would be simply to power straight across them, in order to travel the shortest distance possible. Engineers from MIT, however, have developed a system that allows AUVs to reach their destinations sooner, by traveling out of their way to “go with the flow.” Read More

SeaBird claimed to be world's fastest personal submarine - and it doesn't even have a motor

By - December 29, 2011 7 Pictures
If the amount of personal submarine stories crossing our desks in recent years is any indication, recreational submarines are a burgeoning market. While most personal submarines, such as U-boat Worx’s offerings, employ electric motors powered by a rechargeable battery pack, US-based company AquaVenture has taken a different approach to create what it says is the fastest personal submersible available. This is because the SeaBird doesn’t pack a propulsion system of its own, but is instead towed through the water by a surface vessel. Read More

The smartphone controlled Aquabotix Hydroview underwater vehicle

By - December 14, 2011 4 Pictures
Smartphones can already be used to remotely control a variety of vehicles, including flying toy helicopters and airplanes, or even starting your car. Now remotely operated underwater vehicles (ROVs) can be added to the list with New England-based company Aquabotix rolling out its Hydroview vehicle. Equipped with LED lights and a HD video camera, the vehicle transmits a live video feed to an iOS- or Android-based smartphone, tablet, or a laptop and can be remotely operated by tilting the phone or tablet or via the laptop's touchpad.

Heavy-duty housing lets iPhone shoot video deep beneath the sea

By - December 14, 2011 5 Pictures
If nothing else, the iPhone 4’s ability to shoot 1080p high-def video has certainly done one thing – provided inventors with things to make. There is currently what could almost be described as a gold rush, as products are being designed to augment the smartphone’s camera, to the point that it could be used for all of the same things as traditional, stand-alone video cameras. Some of these innovations have included interchangeable lenses, a mini SteadiCam, and a rugged helmet-mount system. Now, an underwater housing system for the iPhone 4 and 4S is in the works, which will allow users to shoot undersea video at depths of up to 100 feet (30.5 meters). Read More

Dutch Docklands to the rescue for Dubai's World project?

By - November 22, 2011 11 Pictures
The troubled World Project in Dubai, which has been riddled with problems since the global financial crisis in 2009 including rumors that the islands are sinking, may have found salvation. Architectural firm Dutch Docklands has developed, designed and engineered a master plan for 89 floating islands, giving current World investors the opportunity to purchase a floating paradise. The solution would provide investors with an option that's more feasible and cost-effective than building on the existing land masses, whilst also incorporating several environmental benefits.

Latest deep ocean shipwreck discoveries have a silver lining

By - October 12, 2011 13 Pictures
Ocean exploration has always been salted with the allure of sunken treasure, and with precious metal prices hitting new records and new technologies allowing access to deeper sites, that Siren's call has never been greater. Recently, a team of Odyssey Marine Exploration (OME) technicians and archeologists announced finding not one, but two British shipwrecks off Ireland, the SS Gairsoppa and the SS Mantola. Only 100 miles and a World War apart, the two hulks rusting away in the deep Atlantic collectively contain what could prove to be millions of ounces of silver. Read More

ICTINEU 3 submersible dives to depths of almost 4000 feet

By - September 22, 2011 10 Pictures
While NASA makes plans to send man to Mars, there’s still so much we don’t know about our home planet – particularly when it comes to what lies beneath the ocean waves. Over the past few years we’ve seen the emergence of a number of submersibles that bring underwater exploration to a wider audience, such as the C-Quester and C-Explorer lines from Uboatworx and the EGO semi-submarine boat. The latest to catch out eye is the ICTINEU 3, a three-seater (one pilot and two passengers) submersible that is designed to dive to a maximum depth of 1,200 meters (3,937 ft), which its makers claim will make it the world’s ninth deepest submersible.

New cover and lens for GoPro HERO HD actioncam

By - August 22, 2011 6 Pictures
GoPro’s HERO HD is certainly one of the most popular actioncams on the market, perhaps more so now that its long-awaited LCD viewfinder/playback screen is available. As is the case with other digital cameras, however, the glare of direct sunlight can make it difficult to see what’s on that screen. Also, as we noted in an actioncam video comparison, the HERO’s underwater shots tend to be a little on the soft-focus side. Well, two new products from camera gizmo-maker XSories are designed to address both of these situations. Read More
