In a surprising first, researchers found that scalloped hammerhead sharks act like air-breathing marine mammals, holding their breath to stay warm when they deep-dive into cold water for food and making them vulnerable to humanity's deep-sea exploits.

URB has unveiled the "world’s largest ocean restoration project" on the Dubai coast, the stunning and sustainable Dubai Reefs. The floating community is intended to be the center of marine research, eco-regeneration and eco-tourism worldwide.

Back in 2020 we told you about the QuenchSea, a foot-pump-powered portable device for desalinating sea water. Well, its makers are back with the QuenchSea Reel, which uses deep-ocean water pressure to do the same job.

The flapping motion of a new robotic jellyfish is not only good for propulsion, but it can also draw small bits of debris up from the ocean floor without contact. Such a robot could remove trash from delicate ocean environments, like coral reefs.

With their little flipper-like wings, these seabirds aren’t exactly candidates for being adept at pumping iron. But, in fact, they are: more than a million pounds of iron flows from their poop into the water annually, and it's crucial for ocean life.

Much of the heat and carbon produced by humans is absorbed by the ocean. New research has shed light on the role that underwater waves play in moving that heat and carbon around our oceans, an important factor in predicting climate change.

In July last year, Saildrone launched one its sensor-packed unmanned aquatic drones on a voyage of discovery in the North Pacific, tasked with filling in ocean mapping blanks around Alaska's Aleutian Islands as well as off the coast of California.

After nearly 20 years of negotiations, 193 nations have come together to draft the High Seas Treaty, an agreement that will set the world on track to protect 30% of international waters, fund marine conservation and better regulate sea-bed mining.

A new study has shown that foods that come from the ocean or freshwater, known as "blue foods," have the potential to address several important global issues, including nutritional deficits, disease, and climate change.

Green hydrogen can't be viewed as environmentally friendly if it drinks huge amounts of fresh water, or results in the bulk output of toxic chlorine, according to RMIT researchers who say they've come up with a cheap technique that does neither.
-
If you're designing robots for the exploration of oceans on other planets, you want something that's tough, versatile and easy to store in a spacecraft. It turns out that soft-bodied robots inspired by a marine organism may be the perfect choice.

It’s a cruel irony that 70% of the Earth’s surface is covered in undrinkable water. Scientists have now modeled the feasibility of a hypothetical system that can capture water vapor from ocean air and condense it into drinking water, at a large scale.
