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.

First direct evidence that breaking waves cause horizontal eddies

As ocean waves pass from deeper water into the shallow coastal regions, they begin to break, churning up the surf zone waters. At the edges of the crests of the breaking waves, horizontally-rotating eddies (vertical vortices) ...

Our plastics will pollute oceans for hundreds of years

(Phys.org)—Australia's plastic garbage has made its way into every ocean in the world. New research shows that it doesn't matter where in the world plastic garbage enters the ocean, it can end up in any of the five ocean ...

Symmetry breaking during flapping generates lift

(Phys.org)—A small, translucent sea slug called Clione antarctica swims through the cold waters near the polar regions by flapping its wings. At the same time, tiny cilia that circle the sea slug's body in three bands may ...

Eddies drive section of thermohaline circulation

(Phys.org) -- Giant currents that traverse the world’s oceans may not be as stable as previously thought after researchers found a branch of one of these global currents was powered and steered entirely by eddies, one ...

Eddies found to be deep, powerful modes of ocean transport

(PhysOrg.com) -- Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies -- known to be up to 500 kilometers across at the surface -- can reach ...
