BomBoard adds power and performance to its modular PWC

A year and a half ago, BomBoard introduced a prototype of what was billed as the world's first modular personal watercraft, weighing in at a total assembled weight of 150 lbs (68 kg) and kicking out around 40 hp. The company took what it learned from that model and will be launching a new version with a larger engine and other upgrades, resulting in an almost entirely new and more powerful machine.Read More

Mother and son team to pedal across the Atlantic

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.

NASA teleconference on sea level change warns of rising oceans

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 Team tells 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.Read More

Mayflower Autonomous Research Ship to cross Atlantic without a crew

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.Read More

Scientists track subsurface waves the size of skyscrapers

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.Read More

Synthetic material mimics coral's ocean-cleaning attributes

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.Read More
