Arctic melt time lapse

The summer melt of Arctic ice opens up nearly three million square miles of ocean and land.

Underwater Armageddon

A mighty army of dolphins, sharks, whales, seals and gannets hunt down the billions of sardines along South Africa's east coast each winter.

This is the sardine run: an underwater Armageddon, the greatest gathering of predators anywhere on the planet, and the most spectacular event in the world's oceans.

Bait ball feast

In late summer the plankton bloom is at its height.

Vast shoals of herring gather to feed on it, diving birds round the fish up into a bait ball and then a humpback whale roars in to scoop up the entire ball of herring in one huge mouthful.
