00:00:45,962 --> 00:00:50,The frozen seas
are worlds unto themselves.

00:00:50,508 --> 00:00:53,Beneath their ceiling of ice,

00:00:53,345 --> 00:00:56,they have an eerie,
almost magical stillness,

00:00:56,639 --> 00:00:59,cut off from the storms
that rage above.

00:01:03,938 --> 00:01:08,In the winter, the feeble slanting
rays of the sun bring little warmth

00:01:08,485 --> 00:01:13,and the temperature seldom rises
above minus 50 degrees Centigrade.

00:01:13,323 --> 00:01:15,(HOWLING, WHISTLING WIND)

00:01:27,170 --> 00:01:31,For much of the year,
it is dark and cripplingly cold.

00:01:31,299 --> 00:01:34,Yet, there IS life here
at BOTH ends of the earth -

00:01:34,886 --> 00:01:38,the Arctic and the Antarctic.

00:01:48,400 --> 00:01:52,For most animals, whether
they live in or out of water,

00:01:52,195 --> 00:01:55,the winters,
when much of the sea is frozen,

00:01:55,323 --> 00:01:57,bring the greatest challenge.

00:02:01,246 --> 00:02:03,The northern hemisphere.

00:02:03,498 --> 00:02:05,It's February,

00:02:05,208 --> 00:02:07,and as the earth tilts on its axis,

00:02:07,711 --> 00:02:10,the sun's rays
creep slowly northwards

00:02:10,505 --> 00:02:13,and the Arctic emerges
from its harsh winter.

00:02:17,262 --> 00:02:21,The Arctic is a frozen ocean
surrounded by continents,

00:02:21,266 --> 00:02:24,and when the surface of the sea
between the continents

00:02:24,853 --> 00:02:26,freezes from shore to shore,

00:02:26,855 --> 00:02:29,land predators walk out onto it

00:02:29,524 --> 00:02:31,to hunt.

00:02:36,614 --> 00:02:38,It's early March,

00:02:38,867 --> 00:02:41,and the sea is still covered
with ice...

00:02:42,162 --> 00:02:45,But there are patches
of open water - polynyas -

00:02:45,457 --> 00:02:47,that never freeze over.

00:02:47,334 --> 00:02:51,Here, where tidal currents
are squeezed between islands,

00:02:51,921 --> 00:02:55,the water movement is so strong
that ice cannot form.

00:03:01,222 --> 00:03:04,Walruses spend the winter
in polynyas.

00:03:05,435 --> 00:03:08,Here they have permanent access
to the air,

00:03:08,480 --> 00:03:12,but they can also retreat
to the sea to shelter, to hunt.

00:03:26,331 --> 00:03:30,Other sea mammals overwinter
in polynyas as well - in this one,

00:03:30,627 --> 00:03:32,a young bowhead whale.

00:03:42,722 --> 00:03:44,Here, the current is really fast

00:03:45,058 --> 00:03:47,and the shifting ice is dangerous.

00:03:52,816 --> 00:03:54,This whale became trapped

00:03:55,068 --> 00:03:57,when ice encircled it last autumn.

00:04:04,994 --> 00:04:07,There is no food here,

00:04:07,247 --> 00:04:09,but a whale must breathe,

00:04:09,749 --> 00:04:14,and the only place it can do so
for miles around is in this tiny hole.

00:04:18,133 --> 00:04:21,It's living entirely
on its reserves of fat,

00:04:21,261 --> 00:04:23,but now, they're dangerously low.

00:04:23,930 --> 00:04:27,It will be some months yet
before it can escape.

00:04:41,281 --> 00:04:44,Elsewhere, other whales
have also been trapped.

00:04:44,743 --> 00:04:46,These are belugas.

00:04:46,703 --> 00:04:48,Their tiny hole in the ice

00:04:48,955 --> 00:04:51,has been kept open not by currents,

00:04:51,458 --> 00:04:54,but by the belugas'
continuous movements

00:04:54,461 --> 00:04:56,as they rise to breathe.

00:05:02,052 --> 00:05:05,Open water is now
some 20 miles away.

00:05:05,764 --> 00:05:09,It will be two months yet
before the ice melts.

00:05:21,488 --> 00:05:23,The belugas are extremely thin

00:05:23,990 --> 00:05:26,and most of them
are horribly scarred.

00:05:36,044 --> 00:05:39,But their wounds
were not inflicted by the ice.

00:05:48,932 --> 00:05:52,A whale would be a huge prize
for any meat-eating hunter,

00:05:52,852 --> 00:05:55,and these belugas,
trapped by the ice,

00:05:55,689 --> 00:05:57,are within reach of polar bears.

00:06:11,454 --> 00:06:13,Well aware of the danger,

00:06:13,665 --> 00:06:17,the belugas stay submerged
as long as they can,

00:06:17,293 --> 00:06:21,but they can only hold their breath
for about 20 minutes.

00:06:40,692 --> 00:06:44,Catching a four-metre-long whale
that weighs one tonne

00:06:44,696 --> 00:06:46,is no easy task,

00:06:46,448 --> 00:06:50,even if that whale
is weakened by starvation.

00:07:02,005 --> 00:07:05,But a beluga
is well worth waiting for.

00:07:29,574 --> 00:07:31,Day by day,
as the hole gets bigger,

00:07:32,035 --> 00:07:36,it becomes increasingly difficult
for the bear to land a whale.

00:07:40,126 --> 00:07:43,Keeping its fur in good condition
and free from salt

00:07:43,755 --> 00:07:45,is important for warmth,

00:07:45,799 --> 00:07:48,and the bear uses snow
like blotting paper.

00:08:00,772 --> 00:08:03,These belugas have been attacked
by many bears

00:08:03,942 --> 00:08:05,over the last six months,

00:08:05,777 --> 00:08:07,and some have been caught.

00:08:11,157 --> 00:08:14,It may have taken a long time
and a lot of patience,

00:08:14,619 --> 00:08:18,but a catch when it's made
brings abundant rewards

00:08:18,581 --> 00:08:20,of energy-rich blubber.

00:08:31,428 --> 00:08:35,Gulls rely on bear kills
at this time of the year,

00:08:35,265 --> 00:08:37,and the colour of blood
staining the ice

00:08:38,059 --> 00:08:40,attracts them from a long way away.

00:08:44,482 --> 00:08:47,The remaining belugas
still have a long wait

00:08:47,610 --> 00:08:50,before they're released
from their prison

00:08:50,655 --> 00:08:52,and the threat of slaughter.

00:09:21,269 --> 00:09:24,Arctic foxes
also rely on the polar bears

00:09:24,272 --> 00:09:26,to hunt on their behalf.

00:09:26,441 --> 00:09:28,They're the jackals of the north,

00:09:28,985 --> 00:09:32,and scavenge from bear kills
whenever they can.

00:09:40,997 --> 00:09:43,In winter and early spring,

00:09:43,249 --> 00:09:45,they're wholly dependent on bears.

00:09:46,127 --> 00:09:48,Only in the summer,
when the sea ice melts,

00:09:49,089 --> 00:09:52,will they regularly catch prey
for themselves.

00:09:59,599 --> 00:10:02,They're not strong enough
to tackle adult seals,

00:10:03,019 --> 00:10:06,but can certainly take
new-born pups or birds.

00:10:20,704 --> 00:10:22,This canny individual

00:10:22,580 --> 00:10:24,is going to bury its prize.

00:10:24,833 --> 00:10:28,It may need it
during the uncertain times ahead.

00:10:31,798 --> 00:10:33,The presence of bears

00:10:33,717 --> 00:10:38,affects the behaviour of almost all
the animals here, big and small.

00:10:38,471 --> 00:10:41,The bears tend to avoid
the fringe of fragmented ice

00:10:42,100 --> 00:10:43,bordering open water

00:10:44,060 --> 00:10:46,where travelling
can be very laborious,

00:10:46,938 --> 00:10:50,but that very fact
makes this area - the pack ice -

00:10:50,316 --> 00:10:52,a particularly good place

00:10:52,444 --> 00:10:54,for seals to pup.

00:11:03,079 --> 00:11:04,Harp seals breed here.

00:11:04,956 --> 00:11:07,Their pups are born with white coats

00:11:07,542 --> 00:11:11,which camouflage them
very effectively against the snow.

00:11:13,631 --> 00:11:16,Harp seals have
a very short nursing period -

00:11:16,760 --> 00:11:19,a necessity
on this unstable pack ice -

00:11:19,679 --> 00:11:22,but suckling is intensive.

00:11:22,724 --> 00:11:25,The pup feeds for just 12 days

00:11:25,727 --> 00:11:27,on milk that is 45 per cent fat.

00:11:28,146 --> 00:11:30,Then it's abandoned

00:11:30,940 --> 00:11:33,and has to fend for itself.

00:11:36,446 --> 00:11:37,A male hooded seal.

00:11:42,869 --> 00:11:44,This impressive nasal display

00:11:45,121 --> 00:11:48,is used to warn away other males...

00:11:54,881 --> 00:11:56,and to win a mate.

00:11:57,384 --> 00:11:59,Hooded seals also breed
on pack ice.

00:12:00,053 --> 00:12:02,Their pups suckle
for only four days,

00:12:02,722 --> 00:12:06,the shortest nursing period
known for any mammal,

00:12:06,267 --> 00:12:09,and all because
the threat of polar bears

00:12:09,938 --> 00:12:12,caused them to breed
on the unstable ice.

00:12:28,957 --> 00:12:33,Another Arctic seal opts
for the solid ice further north.

00:12:34,337 --> 00:12:37,Because it's easy for bears
to hunt here,

00:12:37,215 --> 00:12:40,these ringed seals
must be particularly vigilant

00:12:40,760 --> 00:12:42,and have to hide their pups.

00:12:46,850 --> 00:12:49,Ringed seals
are comparatively small,

00:12:49,644 --> 00:12:51,so they can give birth
to their pups

00:12:52,147 --> 00:12:54,in little caves or lairs
under the snow.

00:12:55,692 --> 00:12:57,Here, a pup is out of sight

00:12:57,694 --> 00:12:59,and protected from bad weather.

00:13:04,451 --> 00:13:06,In late March and into April,

00:13:06,703 --> 00:13:10,female bears emerge from
winter dens with their new cubs.

00:13:13,001 --> 00:13:16,The mother has not eaten
for at least five months

00:13:16,379 --> 00:13:18,and she's hungry - very...
