Underwater

Although there are glues that work underwater, they typically require at least 24 hours to set – which can be tricky in chaotic marine environments. A new additive, however, reportedly allows underwater resin adhesives to set in just 60 seconds.

Scientists at Carnegie Mellon University have spent a number of years developing modular snake-like robots for all kinds of purposes, and the latest adaptation sees its serpent-inspired tech headed underwater.

If you want to gather oceanographic data over long distances, an "underwater glider" is often the best way to go. A novel system from California-based company Seatrec should soon power such vehicles, utilizing the temperature gradient of ocean water.

A stunning shot looking up at a pair of reef sharks during sunset has won the 2021 Underwater Photographer of the Year contest. The spectacular highlighted images this year span everything from surreal undersea wrecks to rare glimpses of little-seen sea creatures.

Even though lifeguards are essential to maintaining safety at swimming pools, they can't always see everything that's happening. That's where a new swimmer-saving underwater robot is designed to come in.

Things can get very chaotic on the ocean floor, making it difficult for underwater robots to keep from being swept away. New research, however, suggests that by copying the structure of the starfish, they could actually be pressed into place.

When scientists wish to gather oceanographic data over long distances, autonomous "underwater gliders" are often used. A new one is claimed to be highly maneuverable, yet it has no external propulsion or steering systems.

Any unsuspecting swimmers diving off the coast of Cannes may think they've stumbled onto some kind of ancient Easter Island-type civilization swept into the sea, but they'd actually be seeing the work of underwater artist Jason deCaires Taylor.

Baca Architects has been hired to lead the design of the new Australian Underwater Discovery Centre. The whale-like building will be situated 2 km out at sea and partially submerged, offering visitors a view of life below the waves.

When it comes to developing robots that can move efficiently through water, scientists regularly turn to creature’s like jellyfish for inspiration, and a UK research team has just produced one that can swim with the best of them.

While ocean-based fish farms do help take pressure off of wild stocks, they have eco-unfriendly drawbacks of their own. A new underwater robot is being designed to address that situation, by autonomously inspecting the fish and their pens.

Although AUVs (autonomous underwater vehicles) excel at gathering marine data without human intervention, they're still limited by battery life. Texas startup Terradepth has set out to address that problem, with a novel tag-team system.
