A new underwater drone concept could seek and destroy one of the ocean’s most insidious enemies, while earning a profit for plastics recyclers. This marine drone can siphon plastic garbage, swallowing bits of trash in a gaping maw rivaling that of a whale shark.
Perhaps no creature packs a more intimidating punch — especially relative to its size — than the peacock mantis shrimp. It feasts on snails, crabs and other mollusks and crustaceans by smashing through their shells with its front hammer-like claws, delivering 500 Newtons of force. This is powerful enough to punch through aquarium glass.
With no meal for 86 million years, and barely enough oxygen to sustain metabolism, can a single-celled organism really be considered alive? Yes, but only just, according to a new study. A microbial community buried under the ocean floor since the mid-Jurassic era is still hanging on. Their tenacity could pose some interesting questions for the hunt for alien life.
A new robotic jellyfish is powered by hydrogen, and could theoretically never run out of energy as it pulses through the sea. It’s designed to work as a search and rescue or surveillance ‘bot for the U.S. Navy.
The Earth’s crust bends and deforms in response to ocean tides, and this barely noticeable warping affects other bodies of water as well as the land, according to a new study. With exacting precision, scientists in the UK have measured the way Loch Ness sloshes around as all of Scotland bends under the strain of the North Sea’s tides. The lake could be used like a level to gauge the planet’s response to the back-and-forth movement of all its water.

This month, Russian scientists will nearly reach the waters of Lake Vostok, which have been sealed more than two miles under Antarctica’s surface for at least 15 million years. If all goes well, the drill will never touch the fragile ecosystem.
Two pairs of self-propelled oceangoing robots have begun slowly making their way across the Pacific Ocean, setting off Nov. 17 from San Francisco on an epic journey covering 33,000 nautical miles. During their 300-day trip, the robots will collect 2.25 million pieces of data, and attempt to break a world record for the longest distance ever traversed by an unmanned vehicle.
Liquid Robotics, which built the gliders, aims to share all this data with scientists and the public. Through the Oceans portal in Google Earth, you can even follow the expedition online.
You never know exactly what you'll find when you go churning up muck, but apparently odds are pretty good you'll find some viruses. The other day we heard how raw sewage is a hotbed of unknown viruses; now a French team has found the largest virus ever, living in the sea off the coast of Chile.
Earth’s oceans likely started out as space snowballs born far beyond the orbit of Pluto, a new study says. Water-rich comets collided with the young planet after hurtling through the nascent solar system, and probably delivered a significant amount of the water on this planet.
