Weather Buoy

If no one is there, how do we know if it is raining in the middle of the Pacific Ocean? For a transoceanic flight, this is much more than a silly koan. Since the middle of the twentieth century, a network of fixed and floating buoys have been launched to keep track of weather conditions across the world’s oceans. Ranging in diameter from 30 centimeters to 12 meters, these little (and not-so-little) guys keep track of surface conditions on the seas, recording and transmitting data out via satellite for all the pilots, sailors and scientists who need to know what the weather will bring them.
