Landsat Satellites Track Yellowstone's Geothermal Activity

Yellowstone National Park sits on top of a vast, ancient, and still active volcano. Heat pours off its underground magma chamber, and is the fuel for Yellowstone's famous features -- more than 10,000 hot springs, mud pots, terraces and geysers, including Old Faithful.But expected development by energy companies right outside Yellowstone's borders have some fearing that Old Faithful could be cheated out of its energy.

The park funded a study by Lawrence and his co-author Shannon Savage to apply a new perspective to the problem of tracking geothermal activity. Their work is being presented at the American Geophysical Union conference in San Francisco on December 9. Lawrence and Savage used both visible light and heat-sensitive Landsat data channels to get a broad view of the park's geothermal activity....

Whales win, walruses lose in warmer Arctic
