Science of Great Migrations
Description
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.
