Atlantic: The Wildest Ocean on Earth

In the wild North Atlantic, massive whale pods, giant turtles and monstrous jellyfish ride the Gulf Stream, a huge ocean current that becomes a migration super-highway and helps warm Northern Europe. Meanwhile, fishermen battle for survival in mountainous seas as they try to reap the current's natural fertility.

Explore the huge expanses of the South Atlantic and see how spectacular oases of life are able to arise there. The answer lies with the powerful volcanic forces which formed the Mid Atlantic Ridge - the longest mountain range on Earth. Such volcanic undersea ridges and islands punctuate the South Atlantic, and their nutrient-rich upwellings create profusions of life. Huge pods of leaping dolphins, vast, chaotic penguin colonies and the largest gathering of marine mammals on Earth pack the South Atlantic’s extraordinary islands.

In the Tropical Atlantic, everything from dolphins to manatees thrive in the Caribbean's warm, sheltered waters, fringed with coral reefs and rich mangrove forests, but extreme heat in Africa unleashes terrifying hurricanes.
