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

Since 1995, XPrize has been promoting science and technology by setting “Grand Challenges” with cash incentive prizes. On Monday, the organization announced the launch of three new competitions by 2020 as part of its XPrize Ocean Initiative, which is aimed at improving the health and understanding of the world’s oceans.  Read More

Artificial shells for hermit crabs by Aki Inomata (© AKI INOMATA)

About this time two years ago, we looked at the efforts of Miles Lightwood and the Thingiverse community to 3D print shells for hermit crabs, but Tokyo-born artist Aki Inomata has been creating artificial shells for hermit crabs since 2009. Her most recent efforts are intricate and ornate, incorporating ideas on the theme of national identity through depictions of city skylines and vernacular architecture. The hermit crabs seem to like them too.  Read More

Fabien Cousteau, filmmaker, explorer, and grandson of pioneering oceanographer Jacques Cousteau, is set to take a page out of his grandfather’s book by conducting a month-long scientific research mission in the world's only underwater habitat and laboratory. Mission 31 beings on November 12 at the Aquarius Reef Base off the coast of the Florida Keys, marking the 50th anniversary of his the elder Cousteau's historic Conshelf II habitat experiment.  Read More

While traveling in a 'swarm,' as the developers are calling it, the robots will wirelessly...

Over the past few years, jellyfish populations along South Korea's coastline have risen to the point where they are adversely affecting the fish populations and marine industries in the area, costing the country over 3 billion won (about US$2.8 million) each year. A team led by Associate Professor Hyun Myung of the Korea Advanced Institute of Science and Technology however may have a solution with the JEROS (Jellyfish Elimination RObotic Swarm), a series of autonomous robots that work together to track down jellyfish in the ocean and grind them into a fine pulp.  Read More

The Ocean Cleanup Project hopes to utilize the oceans' gyres as a means to collect plastic...

Boyan Slat, an aerospace engineering student at the Delft University of Technology, is working to combine environmentalism, technology, and his creative outlook to rid our oceans of plastic debris. His Ocean Cleanup Project aims to utilize the oceans’ natural gyres (five circular currents in the oceans around the world – two in the Atlantic, two in the Pacific, and one in the Indian) to collect plastic waste.  Read More

When offshore oil drilling rigs are being installed, serviced or dismantled, the workers typically stay in cabins located on adjacent floating platforms. These semi-submersible platforms are towed into place (or travel under their own power) and then their hulls are partially filled with water, allowing them to remain somewhat stable in the pitching seas. Now, a ship is being built to serve the same purpose, but that will be a much more mobile alternative. It will keep from rolling with the waves by generating its own waves, inside its hull.  Read More

The Cyclops research/commercial manned submersible

In three years, if you happen to be 3,000 meters (9,800 ft) beneath the surface of the ocean, keep an eye out for the Cyclops. No, not the hairy giant, but the 5-passenger submersible. Once it’s commercially available in 2016, it should be “the only privately owned deep-water manned submersible available for contracts.” As for why it’s called the Cyclops, just check out its one-big-eye-like 180-degree borosilicate glass observation dome.  Read More

Workers harvest sunscreen-producing bacteria from Norway's Trondheim fjord (Photo: Credit ...

The next generation of powerful sunscreens may have their roots in some unlikely sources – corals from the Great Barrier Reef and bacteria found in the Trondheim Fjord in Norway. When developed, these new sunscreens could offer protection across a wider band of ultraviolet (UV) radiation suspected to cause deadly forms of skin cancer, which current sunscreens don't protect against. The discoveries represent huge breakthroughs, made possible by harnessing the natural sunscreen abilities that these life forms have developed over millions of years to survive the harsh UV radiation in their respective environments.  Read More

When it comes to commercial aquaculture, a lot of people have some legitimate concerns – fish farms can introduce antibiotics, anti-algal chemicals and concentrated fish waste into the ocean; escaped fish can upset the local ecological balance; and wild fish still need to be caught in large numbers, as a food source for some species of farmed fish. While there have been recent efforts to address the first two concerns, the fish-in-the-fish-food problem is now being taken on in two different research projects. These are aimed at replacing the fish content in fish feed with more sustainable ingredients.  Read More
