MIT has developed a predictive tool it says can give ships and their crews a two- to three-minute advanced warning, allowing them to shut down essential operations on a ship or offshore platform.
Combining ocean-wave data available from measurements taken by ocean buoys with a nonlinear analysis of the underlying water wave equations, Sapsis' team quantified the range of wave possibilities for a given body of water. They then developed a simpler and faster way to predict which wave groups will evolve into rogue waves.
The resulting tool is based on an algorithm that sifts through data from surrounding waves. Depending on a wave group’s length and height, the algorithm computes a probability that the group will turn into a rogue wave within the next few minutes.
Subcultron is a swarm of at least 120 self-directing, underwater robots being developed by scientists in six countries to monitor Venice’s polluted waterways and transmit environmental data to government officials.
Microsoft says underwater data centers would be ideal in many ways. First, they can help reduce cooling costs and emissions from a regular data center by taking advantage of the lower surrounding temperatures for cooling, though the capsule doesn’t actually consume water for cooling.
An underwater capsule can also be built and deployed within 90 days. That’s a great turnaround time if your cloud service needs extra help during a major event like the Super Bowl, when tons of users want to access their data in a specific location. A Project Natick vessel could also be dropped off the coast of a disaster zone to enable faster access to data when it counts.
Finally, about half the world’s population lives within 124 miles (200 kilometers) of the ocean. Placing datacenters offshore brings them closer to more users, which in turn would make latency (the time it takes data to transfer from a server to your PC or smartphone) goes down dramatically.
The 21-year-old Dutch is the founder and CEO of The Ocean Cleanup, an ambitious operation involving a massive static platform that passively corrals plastics with wind and ocean currents. The array features a floating V-shaped boom so that fish and other marine life can swim underneath.
Further trials will take place off the coasts of Japan and the Netherlands, and if all goes to plan, the project will officially launch in 2020 and be the longest floating structure ever deployed in the ocean.
In a windowless conference room in Anchorage, a dozen Royal Dutch Shell employees report on the highest-profile oil project in the multinational’s vast global portfolio. Warmed by mid-July temperatures, Arctic ice in the Chukchi Sea, northwest of the Alaskan mainland, is receding. Storms are easing; helicopter flights will soon resume. Underwater volcanoes—yes, volcanoes—are dormant. “That’s good news for us,” Ann Pickard, Shell’s top executive for the Arctic, whispers to a visitor.
Overhead, a bank of video monitors displays blinking green radar images of an armada of Shell vessels converging on a prospect called Burger J. Company geologists believe that beneath Burger J—70 miles offshore and 800 miles from the Anchorage command center—lie up to 15 billion barrels of oil. An additional 11 billion barrels are thought to be buried due east under the Beaufort Sea. All told, Arctic waters cover about 13 percent of the world’s undiscovered petroleum, or enough to supply the U.S. for more than a decade, according to government estimates.
Barrios is one of about 250 Chilean fishermen who have signed on with Shellcatch, a San Francisco startup seeking to profit from the growing demand for sustainable seafood. The company hopes its technology will combat the overfishing and fraud that threaten the international seafood trade. The Pew Charitable Trusts estimates that one out of five fish taken from the ocean is caught illegally, depleting stocks of certain species to levels that imperil their survival. Whether it’s to avoid fines for fishing without permits or going over their quota or simply to boost profits, fishermen often try to pass off one type of fish as another. Oceana, a U.S. nonprofit, ran DNA tests on 1,200 fish samples and found that one-third had been mislabeled, according to a 2013 report. “We think technology in the seafood space can disrupt the way business is being done, which currently involves large amounts of species fraud and illegality,” says Shellcatch founder Alfredo Sfeir. “Technology allows you to know the people behind your fish. That’s how it used to be.”
GoPro's small point-of-view shooters are best known for stunt footage taken on (and high above) the Earth's surface. But these video cameras also excel in the depths, thanks to great lowlight performance and an ultra-wide-angle fixed lens. (If you have an hour, hop on YouTube and search "GoPro underwater.") The latest model, the Hero3+ Black Edition, includes a separate housing that's waterproof to 131 feet, and records video in up to 4K resolution (or a burst of still shots at 30 frames per second) via a 12-megapixel sensor. Screw it onto a hand-held pole mount and you'll be able to grab up-close imagery of fish you're stalking. Or turn the camera back toward you to snap the ultimate underwater selfie
Last summer, NASA’s Global Hawk drones flew over two storms at 60,000
feet and dropped parachute-equipped devices that collected temperature,
humidity and wind measurements. Ferek says that when this information
was integrated into the model, intensity forecasts improved by about 25
to 40 percent. “Only by flying over with Global Hawks and getting data
from 65,000 feet to the surface,” says Ferek, “did we begin to
understand these missing physics.”
