"Underwater drone" channels your inner Cousteau

If you're fascinated by the underwater world, then you probably also think that ROVs (remote-operated vehicles) are pretty neat. Given that their prices can start in the tens of thousands of dollars, though, you've likely never seriously considered buying one. Well, that could be about to change. Utilizing some of the same technologies that have allowed aerial drones to become affordable, Blue Robotics' BlueROV2 could soon be yours for around US$3,000.Read More

Cashed up Ocean Cleanup project to forge ahead with real-world testing

The mounting trash in the sea is a big problem that will take a large-scale solution. Numerous ideas have been put forward, but perhaps none with the big-picture feel of catching plastic waste in floating arms that stretch for 100 km (62.1 mi) across the ocean surface. The Ocean Cleanup Project has now edged a little close towards this goal, banking more than US$1.5 million in funding to move ahead with the first real-world test of its garbage collection barriers.Read More

Adidas runs with first batch of ocean plastic footwear

The first batch of Adidas footwear to be produced using ocean plastic has been made available. The sportswear brand partnered with Parley for the Oceans to create the Adidas x Parley, which is made with plastics collected in coastal areas of the Maldives, as well as illegal deep-sea gill nets.Read More

Satellites reveal El Niño's impact

Data from NASA satellites is being used to help scientists analyze how El Niño – a natural, regularly-occurring event that sees large volumes of warm water move through the Pacific Ocean – is affecting a population of tiny ocean plants. A decline in the number of these plants can cause big disruptions to coastal fishing industries.Read More

Stepping back in time to protect the future of the Great Barrier Reef

Australia's stunning Great Barrier Reef is changing, and not for the better. In the years since the industrial revolution, the increasing amount of carbon dioxide in the atmosphere has made the oceans warmer and also more acidic, which is bad news if you're young coral trying to make your way in the world. In the first study of its kind, a team of scientists has altered the seawater chemistry in a natural section of the reef to mimic pre-industrial conditions, observing just how well the coral was able to grow before we came along and altered the landscape. Gizmag spoke with one of the researchers involved to learn how stepping back in time might make for smarter steps into the future.Read More

MIT develops early warning system for rogue waves

The open ocean is daunting enough when it's relatively calm, but add in the existence of huge, seemingly randomly-occurring walls of water, and it becomes downright terrifying. Now, researchers at MIT have come up with a new way of predicting when a rogue wave is about to hit, giving ships and offshore platforms a few precious minutes to prepare for the dangerous event.Read More

Detailed seafloor gravity map brings the Earth's surface into sharp focus

Not so long ago the ocean floor was as unknown as the far side of the Moon. Now, an international team of scientists is using satellite data to chart the deep ocean by measuring the Earth's gravitational field. The result is a new, highly-detailed map that covers the three-quarters of the Earth's surface that lies underwater. The map is already providing new insights into global geology.Read More
