NASA’s new LVIS sensor to map polar regions with ‘return to sender’ technology

NASA’s Land Vegetation and Ice Sensor has yet to leave the atmosphere, but that’s the long-term plan for this high-flying mapping technology. In the nearer future, LVIS will produce high-resolution, three-dimensional maps of Earth’s unexplored polar regions, allowing scientists to follow changes in ice cover more accurately than ever before. Since 1998, LVIS has mapped rainforest canopies in Costa Rica, surveyed Gulf Coast ocean topography, and even tracked ivory-billed woodpeckers …

Hurricanes and Oil Will Mix

A hurricane as strong as Katrina may soon be on a collision course with the Gulf oil spill to create a “double-whammy of worst-case scenarios.” That’s the next potential nightmare looming ahead according to Heidi Cullen, one of several scientists who addressed a briefing on 30 June for Congressional staff. “The Deepwater Horizon oil spill is a worst-case scenario. And, I would say that the fear in the back of …

(CORRECTED*) Gulf Gusher: Oil-spill science has advanced, but data is sparse

Since the Deepwater Horizon oil-drilling platform sank on April 22, millions of gallons of oil and gas have spewed into the Gulf of Mexico. As efforts to staunch the undersea flow continue, scientists (including many AGU members) are working round-the-clock to determine where the oil is going, what’s happening to it, and how it is affecting the environment. Much is unknown about what the effects will be from a spill …
