Another round for noisy ocean temperature test
- eds.
It's a deal a talk show host would kill for: $35 million to sound off for a while. But there's one other aspect of the bargain that might be a bit tough for the average radio personality: You've got to listen to your own noise and gauge whether the world is warming. Luckily, that's nothing new for oceanographer Walter Munk, who last week won funding from the Defense Advanced Research Projects Agency to conduct a second trial of his underwater sonic thermometer of the world's oceans. Sound waves are pulsed form underwater loudspeakers to receivers thousands of miles away. By the measuring the elapsed time, Munk and his collaborators can precisely measure temperatures in entire ocean basins and watch for signs of global warming.
