Ocean surface wave

Ocean surface waves are surface waves that occur at the surface of an ocean.

They usually result from distant winds or geologic effects and may travel thousands of miles before striking land.

They range in size from small ripples to huge tsunamis.

There is surprisingly little actual forward motion of individual water particles in a wave, despite the large amount of forward energy it may carry.

The great majority of waves one sees on an ocean beach result from distant winds.

Three factors influence the formation of "wind waves": Windspeed; length of time the wind has blown over a given area; and distance of open water that the wind has blown over (called fetch).

The Perfect Wave: Beyond the Sea

The Perfect Wave: Beyond the Sea

Deutsche Welle (Sep. 17, 2013) There are around 20 million active surfers worldwide all chasing the same thing: the perfect wave. The problem is that, as a natural phenomenon, the perfect wave is pretty hard to come by. The thrill of the chase has spurred on a new industry, with businesses competing to design the best artificial wave-generating systems. In Bilbao, one German seems to have cracked it. Her concept, "Wavegarden," has become a huge success.

Greener Energy Exploitation for the Ocean Blue

EFE (Dec. 3, 2012) In the middle of the Pacific off the coast of the US state of Oregon, waves rock an elaborate yellow buoy that is actually a testing system for wave energy technology called Ocean Sentinel. It is part of the relatively new technology that aims to produce sustainable and green electricity using the endless sway of ocean waves.

Scientists Target UVA Rays for Future Sunscreens

Reuters (Nov. 25, 2013) British scientists have created a molecule they say could greatly improve the effectiveness of sun-screens and reduce the incidence of skin cancer. Whereas most sun-screens protect against exposure to short-wave, ultraviolet B rays, the scientists are targetting long-wave UVA rays which they say cause just as much damage. Jim Drury has more.

Italy Makes Waves With Sea Power Plan

Reuters (June 25, 2013) An Italian energy company is preparing to build the world's first sub-surface wave farm with machines designed to utilize the motion of the Mediterranean Sea for power generation. The first prototype generator - capable of powering 80 homes - is undergoing onshore tests before being towed out to see to start work next month.
