Narwhals, beluga and bowhead whales, which you can hear in the background, make their homes in the Arctic. There are about 100,000 narwhals in the world, and the vast majority of them - about 50,000 to 70,000 - live in the Arctic waters of Greenland.http://www.podcast.noaa.gov/audio2007/narwhal-podcast-04-19-2007.mp3 Researchers Find Global Positioning System Is Significantly Impacted by Powerful Solar Radio Burst- April 6, 2007 It came from outer space traveling 93 million miles in eight minutes. Once it arrived on Earth, there was no mistaking the fact that a solar flare that produced an intense radio burst a day later affected the satellites that make up the Global Positioning System. Many of the GPS satellites were not available to technology dependant on them, as well as other communication technologies using radio waves, such as cell phones, bank money transfers and navigation systems.http://www.podcast.noaa.gov/audio2007/solar-flares-gps-podcast-04-06-2007.mp3 |
