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.

Underwater robots help discover hidden faults

(Phys.org)—Hidden beneath ocean waves and masked by sand and mud on the seafloor, underwater faults are notoriously difficult to see and even more difficult to study. As a result, geologists struggle to evaluate the risks ...

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.
