Second Life Insider reports that NOAA has set up a Second Life sim called Meteroa
The NOAA's sim is called Meteroa, which is derived from the Greek adjective meteoras which means 'suspended in the air' (Full disclosure, I'm Greek). On this lovely island sim you can find fully interactive educational demonstrations about the ocean and weather. Examples include a sea life submarine ride created by The Magicians, and two different tsnuami demos by Aimee Weber Studios and Electric Sheep Company. Other fun stuff includes a demonstration of a real-time temperature map powered by Yahoo, narration by Exploratorium Chief Scientist Paul Doherty, an airplane ride into a hurricane, and a melting glacier demonstration.
Meteroa includes instructional tsunami videos and a sea life submarine ride.
