For seven weeks each winter, we live on Isle Royale National
Park, a remote island wilderness in Lake Superior, North
America. Here we follow the lives of a population of wolves and
moose that inhabit the island. Sea turtles are the ancient
mariners of our oceans. After hatching on a beach, they cross
thousands of miles of ocean to reach areas with food. Yet,
little is known about where these green sea turtles go and how
they migrate.
