1802 The Seals of Sable Island | Changing Seas | Preview

Season 18 | 2m 46s

Each winter, Sable Island transforms into the planet’s largest gray seal breeding colony. The Canadian government has studied this seal population since the 1960s, and now experts from the U.S. are conducting a unique physiological study on mom and pup pairs to better understand how iron transferred during lactation influences a pup’s survival.

Major funding for this program was provided by The Batchelor Foundation, encouraging people to preserve and protect America’s underwater resources. Additional funding was provided by The Parrot Family Endowment for Environmental Education. Distributed by American Public Television.
