Science Of Great MigrationsStreaming Video - 2013
Travel the world to investigate the mysteries behind some of the most impressive and puzzling migrations. Watch the intricacies of placing the first radio transmitter on a butterfly and what this triumph of miniaturization may reveal. Follow ingenious scientists tracking elusive elephant seals in the dark and frigid depths using a "daily diary" - an advanced tagging device with sensors that monitor temperature, speed, and light - designed especially to find out what these creatures do during the annual ten months they disappear beneath the ocean surface. And meet a man whose life mission has been to study and advocate for the elephants of Africa, only to have historic floods destroy almost everything he has.
