Nordic marine energy technology leader Minesto, a spin-off from Swedish airplane manufacturer Saab, has won an Industry Pioneer Award at the International Tidal Energy Summit in London.
Minesto was awarded the prize for having proved that it is possible to harvest electricity from low velocity currents using the step-change Deep Green power plant.A prototype of the Deep Green ‘underwater kite’ marine power plant is now producing electricity in the waters off Northern Ireland.This is the first time ever a marine power plant designed for low velocity currents produces electricity at sea. The ocean trials verify the new technology's ability to unlock ocean currents as a renewable energy source.

As six-legged robots go, other than its nifty red and yellow paint job, the Crabster robot has a pretty standard look. It isn’t the biggest hexapod, like the impressive two-ton Mantis, or a tiny hexapod with a weird gait, like Boston Dynamics’ RHex. What makes Crabster special isn’t so much what it is but where it will walk—the robot was designed to navigate the seafloor.
Ocean researchers already use both autonomous and remote-control undersea vehicles, but propulsion systems tend to kick up sediment, adversely affecting visibility, and lack the power to deal with strong currents.
Crabster’s creators designed the robot to solve these problems. Developed by the Korea Institute of Ocean Science and Technology (KIOST), the robot can withstand heavy currents by changing its posture (roll, pitch, and yaw), and the robot’s measured gait won’t significantly disturb sediment.
Crabster is lowered to the seafloor by crane and remains attached to an umbilical for power, limiting where it can go but allowing for continuous operation. Four operators remotely drive the robot from the surface—directing and monitoring its movement, manipulators, cameras, lights, and sonar.
On the seafloor, the half-ton robot illuminates murky water with a spotlight, records what it sees with ten onboard cameras, and uses its two front legs to pick up and manipulate objects. Researchers hope to send Crabster to explore shipwrecks where they can return small treasures in the robot’s retractable tray. They’ll haul larger objects by attaching a tow cable connected to the vessel above.
Crabster recently took its first dip in the ocean and will soon head out to sea to begin work 200 meters below the surface. Eventually Crabster’s engineers hope to give it an onboard power source, and we imagine future iterations might combine the best of both worlds—a Crabster that folds its legs to go swimming and, when a stroll better suits its purposes, deploys its legs for a landing on the sea-floor.
Santa Claus — or Scuba Claus, as he’s known around the Vancouver Aquarium — accidentally dropped his jingle bells in the aquarium’s Strait of Georgia exhibit Thursday and was forced to make a frosty dip to retrieve them,...
Seahack: participate in sea exploration! Boing Boing Five years ago this month, my pal, BB contributor, and IFTF colleague Ariel Waldman created Spacehack, a directory of projects through which anyone can participate in space exploration.

The Mayapán Taboo Cenote Project will undertake an extensive exploration of the underwater cave, Cenote Sac Uayum, to document 20+ submerged skeletons and artifacts. Team leader and National Geographic Grantee Bradley Russell will also investigate the modern belief that a supernatural power- a feathered serpent- guards the water within.
With support from The Waitt Foundation for Exploration and The National Geographic Society, The Mayapán Taboo Cenote Project has concluded its first season of exploration at Cenote Sac Uayum, a sacred, water-bearing sinkhole located at the Postclassic Maya political capital of Mayapán, Yucatan, Mexico (1100-1450AD).
My co-directors, Eunice Uc (INAH Centro Yucatan) and Carlos Peraza Lope (INAH Centro Yucatan), and I have enlisted the help of diver Rait Kütt and diver/archaeologist Lisseth Pedroza Fuentes to explore and document the various ceramics and human remains that indicate use of the cenote by the area’s ancient inhabitants.
