All aboard: A female polar bear and her cubs play in the snow in Canada after a long winter's rest in the denPlayfully clambering over their doting mother these polar bear cubs spring into action for the most sociable time of the year.
Across the polar regions from Norway to Canada these images show the intimate relationship between polar bear mothers and their young as they emerge from their winter hibernation.
Each winter females dig dens, where they give birth to their cubs - usually two, but sometimes as many as four.

The snow den, the mother's body heat and her milk, which is high in fat content, enable the cubs to keep warm and grow rapidly before leaving the den in March or April. Short trips are made to and from the den for several days as the cubs get used to the outside temperatures. Then the family leaves and makes its way to the sea ice, where the mother teaches, hunts for and protects her cubs.

But not before a bit of light play in the snow.
Photographer Steve Bloom has spent hundreds of hours in the Arctic regions, photographing the amazing interactions from lounging around in the snow to diving head first into the icy waters looking for food.

'Imagine a world without polar bears.
'It seems unthinkable, yet as climate change gathers pace, the Arctic ice floes upon which the polar bear depends are beginning to break up.

'The irony is that the polar bear represents one of conservation's greatest successes: thanks to an international convention controlling the hunting of the species.'
