From Wikipedia:
Hydrogen Challenger is a 66 meter (216′ 6″) refitted coastal tanker for mobile hydrogen production, it is fitted with a vertical axis wind turbine that generates electricity for the electrolysis of water to fill the hydrogen storage tanks. The total storage and transportation capacity is 1,194 m³ (42,000 ft3), it is stationed in the German Bight or near Helgoland (where the most wind is) and docks in Bremerhaven where the produced hydrogen is delivered to the market.

“I’ve been struggling my whole life to figure out how to reach people and get them to understand they’re connected to the ocean,” Dr. Earle said.

“But I go to the supermarket and still see the United Nations of fish for sale,” she said. “Marine sanctuaries are still not really protected. Google Earth gets all this information now and puts it in one place for the littlest kid and the stuffiest grownup to see in a way that hasn’t been possible in all preceding history.”

By choosing among 20 buttons holding archives of information, called “layers” by Google, a visitor can read logs of oceanographic expeditions, see old film clips from the heyday of Jacques-Yves Cousteau and check daily Navy maps of sea temperatures.

By eating the algae, the salps turn the algae and their carbon dioxide into faeces which drops to the ocean floor. They also take carbon to the floor with them when they die after a short two-week life cycle.

This is thought to be a natural form of carbon sequestration similar to what scientists are trying to do with carbon capture from emission sources such as power stations.

Dr Baird said Australian salps are biologically closer to vertebrates such as humans than to jellyfish because they have the rudiments of a primitive nervous system.

‘They are interesting because they are the fastest reproducing multi-celled animal on the planet and can double their numbers several times a day.’

A bane of Big Oil’s offshore rigs could become a boon for renewable energy.
By tapping the natural motion of slow-moving water, a new hydrokinetic generator could open vast new swaths of the ocean for energy production.
When ocean currents flow over any kind of cylinder, like the long cables that hold drilling platforms in place, small vortices are created. They eventually spin away, or shed, causing vibrations that over time can destroy an oil rig’s moorings.
Now, a University of Michigan engineer who long worked on suppressing this phenomenon, has developed a prototype energy-harvester that can capture the mechanical energy it creates.

Unlike other wave energy systems currently under development around the world, the CETO wave power converter is the first unit to be fully-submerged and to produce high pressure seawater from the power of waves.
By delivering high pressure seawater ashore, the technology allows either zero-emission electricity to be produced (similar to hydroelectricity) or zero-emission freshwater (utilising standard reverse osmosis desalination technology). It also means that there is no need for undersea grids or high voltage transmission nor costly marine qualified plants.

Giant Food announced support for the principles of the Conservation Alliance for Seafood Solutions, a coalition of nonprofit groups that works with retailers to change the way they buy seafood.

Giant said it is committing to work toward buying environmentally responsible products, making information on seafood products readily available and supporting policy changes that have positive environmental impact. The company’s seafood buyers are now also ranking their purchases on how plentiful the species is, how it is caught and what effect fishing has on the species’ natural habitat.

They have developed a cutting-edge underwater listening system to protect the creatures from their number one killer: ships. The Massachusetts Bay network can track right whales by their signature call – and in as little as 20 minutes warn mariners to slow if they’re too close.

The devices are also giving scientists unprecedented insight into how the creatures change behavior to respond to the cacophony of man-made noises in the bay.

“We need to listen to these whales” to save them, said Christopher W. Clark, director of Cornell University’s Bioacoustics Research Program, which developed the technology with Woods Hole Oceanographic Institution.

Clarks said an increasing number of pipelines, cruise ships, tankers, and construction projects are drowning out the whales’ soft calls, making it difficult for them to connect. Clark has evidence that the whales simply don’t “whoop” when the bay gets too noisy.

“In the world of right whales, we know it’s a noisy place to live,” Clark said in an e-mail. “Underwater [is] not much different than living on the tarmac at Logan.”

The boat made of recycled aluminum relies on the energy of waves to move two fins at its bow and propel it forward. Horie said it is a sturdy vessel, designed to right itself if it capsizes. But it is equipped with an engine and an 11-metre sail mast for emergencies.

The journey – which would take a diesel-powered boat about 10 days to complete – is expected to take Horie about 2.5 months. He will take along rice, canned food, microwaveable meals and beer.

Solar panels atop the catamaran will power the microwave and Horie will also have a satellite phone and access to e-mail.
