Standing on the frozen sea, they endure
the full force of the Antarctic storms

Only by huddling together can they can
survive the appalling winter months

They take it in turns to bear
the brunt of the gales

They can only live here at all because
Antarctica is surrounded

by the Great Southern Ocean and no land
predators have been able to reach it,

so unlike Arctic animals,
they're not threatened by polar bears

The sea is still frozen

But one seal, nonetheless,
manages to stay here,

even throughout the winter...

... the Weddell seal

Underwater, it's protected
from the storms above

But it must have access to the air
all year - in order to breathe

And they keep their breathing holes open
- with their teeth

Only by continually scraping away at the
ice can they maintain access to the air

But that means that their teeth
get badly worn down

Then they can no longer hunt
and eat effectively

Weddell seals die young

The continent of Antarctica
is so isolated

and so high - almost five
thousand metres in places

- that it's considerably colder
than the Arctic

lce slides slowly down from its centre
towards its rim in immense glaciers

During winter, the continent effectively
doubles in size as the sea freezes over

lce forms around its shores
and extends outwards

for hundreds of miles around
the entire land mass

Under the sea-ice live small
shrimp-like creatures - krill

They have been here all winter

During these dark months, they feed by
scraping algae from the ice

Remarkably, they also
shrink in size

and revert to their juvenile
form to save energy

As the temperature
rises in spring,

the ice begins to melt and little air
bubbles trapped within it are released

Microscopic algae grow around these
bubbles and the krill now graze on them,

gathering them up with
their beating legs

As the sun's rays grow stronger
and penetrate deeper into the water,

floating algae begin to
flourish and krill leave

the dwindling ice and gather in swarms
as they harvest this new crop

Far to the north, beyond the
blanket of sea ice,

chinstrap penguins have been
overwintering in the open ocean

The occasional iceberg gives
them the chance of a rest

- if they can get onto it

But at this time of year, where they
really want to be is on land
