Sable Island is a National Park Reserve off the coast of Nova Scotia, Canada. This twelve mile long crescent, isolated in the Atlantic, is known for its incredible wildlife — from wild horses to birds and uniquely adapted insects. The world's largest grey seal breeding colony, some 400,000 strong, flourish on this remote island home. In June of 2011, scientists tagged a handful of Sable Island's seals with satellite tracking devices and followed their movement for six months in intimate detail. Explore the map to see how five of these seals interact with the island and surrounding sea.
