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.

Scientists making fishy robots for naval research

Autonomous robot maps ship hulls for mines

For years, the U.S. Navy has employed human divers, equipped with sonar cameras, to search for underwater mines attached to ship hulls. The Navy has also trained dolphins and sea lions to search for bombs on and around vessels. ...

Jellyfish inspires latest ocean-powered robot (w/ video)

American researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of ...

Full Titanic site mapped for 1st time

Researchers have pieced together what's believed to be the first comprehensive map of the entire 3-by-5-mile Titanic debris field and hope it will provide new clues about what exactly happened the night 100 years ago when ...

Helping robots hold on

Since the 1970s, when early autonomous underwater vehicles (AUVs) were developed at MIT, Institute scientists have tackled various barriers to robots that can travel autonomously in the deep ocean. This four-part series examines ...

Bizarre squidworm discovered

The bizarre, newly-revealed squidworm -- a free-swimming worm with up to 10 squid-like limbs -- is one of a host of strange discoveries that await scientists in the vast, largely unexplored spaces of the deep ocean.
