Wave Glider "Alex" Predicts Isaac's Path

Hurricane Isaac 2012: Wave Glider Robot ‘Alex’ Helps Forecast Path, Track and Trajectory of Storm

Tropical Storm Isaac, which became a Category 1 hurricane as it marched across the Gulf of Mexico Tuesday, is threatening a long stretch of the coast from Louisiana through the Florida Panhandle. Residents of those states are anxiously following the path of the storm, but beyond Google and, how will we know the trajectory of this particular hurricane?

The Wave Glider, which was built and introduced by Sunnyvale, Calif.-based Liquid Robotics in 2008, is an autonomous ocean vehicle designed to measure everything from wave movements to air pressure, which is completely powered by the waves and the sun.

"This allows it to run for long periods of time, because it never runs out of fuel," said Roger Hine, founder and CTO of Liquid Robotics.

S.S. Terra Nova found

Polar expedition vessel S.S. Terra Nova Discovered.

August 13, 2012 — Last month, during routine functional performance testing of the mutibeam mapping echosounders on the Schmidt Ocean Institute’s flagship R/V Falkor, the team aboard—including researchers from the University of New Hampshire, Ifremer, and Woods Hole Oceanographic Institution—discovered the S.S. Terra Nova, a whaler, sealer and polar exploration ship that sunk off the southern coast of Greenland in September, 1943, after being damaged by ice.

The performance verification of R/V Falkor’s scientific echo sounders precedes oceanographic research cruises set to begin in 2013. The tests included a shallow water survey off the southern coast of Greenland to assess the Kongsberg EM710 multibeam mapping echo sounder’s performance in complex topography. The testing took place on July 11, 2012, as part of the planned R/V Falkor field trials during the transit of the vessel from Newcastle, UK to Nuuk, Greenland

Advance Warning For Solar Flares Hinges On Surprising Hypothesis

Advance Warning System For Solar Flares Hinges On Surprising Hypothesis

"Scientists may have hit upon a new means of predicting solar flares more than a day in advance, which hinges on a hypothesis dating back to 2006 that solar activity affects the rate of decay of radioactive materials on Earth. Study of the phenomenon could lead to a new system which monitors changes in gamma radiation emitted from radioactive materials, and if the underlying hypothesis proves correct (abstract), this could lead to solar flare advance warning systems that would assist in the protection of satellites, power systems and astronauts."
