With the goal of drawing attention to the mass extinction of species caused by human activity, a mother-and-son team from South Africa is aiming to cross the south Atlantic on a customized boat powered solely with a pedal system. Experienced adventurer Davey du Plessis (27), a raw vegan environmentalist, author and speaker, will lead the 6,450-km (4,008-mi) crossing that is expected to launch in late November, weather permitting. His mother, Robyn Wolff (50), who is also vegan, will be on the boat pedalling with him.
Climate change has a huge impact on the health of the world's oceans. In an attempt to find a solution for carbon dioxide pollution in the oceans, nanoengineers at the University of California, San Diego have developed micromotors that autonomously move through water, removing CO2 and converting it into usable material.
On Aug. 26, NASA held a media teleconference regarding current predictions on sea level rise, highlighting the risks to coastal populations in low-lying areas, and the inherent problems in creating reliable global models. A panel of experts from NASA's recently-founded Sea Level Change Teamtells us that ocean levels are inexorably on the rise, but gaps in our understanding and ability to survey risk regions mean we don't know just how fast the change will take place.
The team at U-Boat Worx (UBW) has produced a number of futuristic-looking, submersible craft designs over the years, including the Ferrari-esque HP Sport Sub 2 and the superyacht-friendly Sub 3. The latest addition – the C-Researcher – is claimed to be the world’s first fully-transparent, 3-person underwater craft capable of diving to the formidable depth of 1,700 meters (5,577 feet).
In May, the Ocean Cleanup project announced that its first deployment would be delivered in the Korea Strait next year. That will pave the way for its ultimate goal of cleaning up the Great Pacific Garbage Patch. With that in mind, a research expedition at the Garbage Patch has just been completed.
Have you ever wondered why the Celtic Sea, located off the south coast of Ireland, is home to so many marine predators? No? Well, scientists at Britain’s National Oceanography Centre have. This month they set about finding out, using a long-endurance autonomous surface vehicle known as the C-Enduro.
If you should encounter a crewless ship out on the Atlantic Ocean in a few years, don’t worry about it being the ghostly Flying Dutchman … it may be the Mayflower, however. No, not the square-rigger that brought Pilgrims to America, but the Mayflower Autonomous Research Ship (MARS). Plans call for the wind- and solar-powered trimaran to sail itself from Plymouth, England to Plymouth, Massachusetts in 2020 – the 400th anniversary of the original ship’s journey – carrying out a variety of research projects along the way.
When you think of ocean
waves, most people will imagine sitting on a beach watching breakers
roll in from the horizon. However a group of scientists from the
University of Miami have been tracking waves of a different breed –
unseen colossal, skyscraper-tall underwater waves that are present
in every one of our oceans.
Humanity's industrial processes have a huge impact on the and, releasing harmful substances such as mercury, arsenic and lead into the water. Chinese researchers are hoping that synthetic coral that mimics the ability of the real thing to collect harmful heavy metals from water could help in the clean up effort, with tests on the effectiveness of the aluminum oxide structure so far showing promising results.
Although wave energy-harvesting systems are often just presented as
concepts that may someday see actual use, one was recently deployed in
Hawaii to provide power to the municipal grid. Built by Northwest Energy
Innovations, the Azura device will remain in operation for a 12-month
assessment period, with an eye toward eventual commercialization.
