Fish-tracking robots take to the seas and skies off Portugal

A unique field experiment being conducted off the coast of Portugal this week combines ocean robotics and marine biology in a complex aquatic dance. Researchers are using a fleet of robotic vehicles to track over a dozen ...

New underwater robot swims and senses like a fish

In recent years, robotic underwater vehicles have become more common in a variety of industrial and civil sectors. They are used extensively by the scientific community to study the ocean. For example, underwater robots have ...

Robotic fish navigate flowscapes

The EU funded European research project FILOSE has developed robots with a new sense - lateral line sensing. All fish have this sensing organ but so far it had no technological counterpart on man-made underwater vehicles.

Tiny reef speedster challenges tuna in the ocean sprint

(Phys.org)—Tiny coral reef wrasses can swim as fast as some of the swiftest fish in the ocean – but using only half as much energy to do so, Australian scientists working on the Great Barrier Reef have found.

First 3-D map of under the East Antarctic sea ice

For the first time in East Antarctica, climate scientists have produced a three-dimensional (3-D) map of the surface beneath a sea ice floe, revealing an inverted complex topography evocative of lakes and mountain ranges.

Aquatic robot audits health of seabed

The watery depths of Western Australia's Ningaloo coast will be audited by marine engineers and scientists this week using an aquatic robot and technology developed by University of Sydney mechatronic experts.
