Ocean

By using advanced microscopes and imaging technology to study tiny pockets of liquid trapped in ancient minerals, scientists have gained new insights into how seawaters have changed over time, and how they might do so in the future.

Scientists from King Abdullah University of Science and Technology studying tiger sharks have leveraged their far-roaming tendencies to map out the largest seagrass system in the world, by using cameras attached to their backs.

The seafloor is rich in valuable metals, but gathering them is disruptive to the environment. An international project has now tested a system called Apollo 2, which can vacuum up metal nodules without kicking up sediment.

Ever wonder how deep-sea fish and other animals are able to survive in an environment where the water pressure would kill us humans? According to a recent study, the secret lies in a chemical that occurs naturally in their cells.

The National Oceanic and Atmospheric Administration has again joined forces with Saildrone to chase hurricanes in the Atlantic Ocean using unmanned surface vehicles, and captured footage from inside the first Category 4 storm of the 2022 season.

Japan's solar potential isn't great, but it does sit right next to one of the world's most powerful ocean currents – so the country is searching for novel ways to bulk up its green energy generation in the form of giant deep ocean turbines.

An international team of scientists and cartographers has released the most detailed map of the seafloor of the Southern Ocean that surrounds Antarctica. It covers 48 million km² and includes the deepest spot yet found in the region.

Following a number of technical setbacks, the Mayflower autonomous research vessel has successfully crossed the Atlantic Ocean, clocking up 3,500 miles and arriving in Halifax, Nova Scotia, on June 5.

It would cost a lot of money to send a boatload of marine scientists across the Atlantic Ocean, all of them conducting research along the way. That's where the Oceanus will come in, as plans call for it to do the job without any crew aboard.

Measuring ocean acidification is possible to an extent with sensors fitted to stationary buoys and vessels, but a newly fitted out deep-diving underwater drone promises to fill in the blanks in a big way.

While AUVs (autonomous underwater vehicles) are invaluable for gathering oceanographic data, they also tend to be fairly large and very expensive. The Hydrus offers a much smaller, less costly alternative, which still packs a lot of punch.

Harvesting sea urchins by hand can be tricky, often resulting in painful pokes through diving gloves. That's where the C Disc and the C Bud come in, as both systems vacuum urchins off the seabed and into a boat, net or shore-located container.
