Each spring, the Arctic Ocean undergoes an extraordinary transformation.

An area of sea ice the size of Europe melts, exposing the rich waters beneath.

Short-tailed shearwaters have travelled 10,000 miles from Australia to be here.

18 million visitors darken the skies, the largest gathering of sea birds on the planet.

Humpback whales have come all the way from the Equator to feed in these rich polar water.

Their giant tails are five meters across.

Simply raising them above the surface give the whales enough downward momentum 

to reach the great swarms of krill and herring below.

The shearwaters follow the giant's lead.

For those who can get here, in summer, these waters provide a feast of epic proportions.

But the good times will be very short. a problem that faces all life in the polar regions.
