Our planet is a blue planet

Nearly three quarters of its
surface is covered by the oceans

Their enormous size and the fact
that we know so little about

many of the creatures
that live there,

presented the film-makers
behind the Blue Planet series

with some very difficult challenges

The series took the best part
of five years to make

and we filmed in nearly two hundred
locations world-wide

Much of the behaviour of
the animals in the series

had never been filmed before
and some was new to science

To get it, the Blue Planet team
were helped by researchers

at the cutting edge of marine
science all over the world

This film is about how we
worked with those scientists

and were able to see
so much that is new

One of the least known and hardest
animals to film is the blue whale

lt roams thousands of miles of open
ocean and can move at thirty miles an hour

You have to be very lucky even
to catch up with one

This, this immense body
is just the tip of the flank

of the biggest creature that
exists on the planet, the blue whale

Over 30 metres long and weighing
as much as 200 tonnes,

lt's larger than the
biggest dinosaurs

And yet its migration routes
are still largely unknown

and we have no idea
where blue whales breed

The biggest research
project trying to solve

these mysteries is
based off California,

working with one of the largest
remaining populations of blue whales

Marine biologist, Bruce Mate,
is pioneering

a new technique which uses electronic
radio tags to send signals to satellites

Amazingly we don't know where most
whale species are at least half the year

and it's really important that
we know their critical habitats,

the places where they feed,
breed, calve and migrate

because those are the areas
that they can't do without

We have to be very careful
not to frighten them off,

but as we approach you can see the
flukes, you can see the head start to rise

When it blows you know you're in the
presence of a huge, huge animal

There's a sense of intimidation there
which you can't help,

just by the sheer
size of the animal

Squeeze in right
Alright!

Oh yeah!

The dart is little more
than a pin prick to the whale

and in under six months
it will fall off

The little tag sends up
signals to the satellite

that records the whale's exact position
each time it surfaces to breathe

The latest results confirm that
this population commutes each year

from Oregon in the north to Mexico
and Costa Rica in the south,

with many whales over-wintering
in the Gulf of California

For three years we had cameramen
on stand-by all along this migration route

using a microlite and helicopters
to try to film blues

from the air without
disturbing them

The microlite was specially adapted
for landing on the water

so the cameraman could jump
in ahead of the whale

to try and get an underwater shot

But soon the whales headed out
of microlite and helicopter range

and we had to follow them south
into the Gulf of California

There we worked with another
marine biologist, Diane Gendron

lf we want to do an estimation
of the population,

an estimation of the
numbers of blue whale

who use the Gulf of
California we need to know

if we're looking at the whole
population or just part of it

And that's what we're doing
with the aerial transect,

We're trying to estimate
the number of blue whales

that use the Gulf of
California during winter

Pilot, Sandy Lanham, has an expert eye
for spotting blue whales from the air

For the last ten years
she'd worked with biologists

studying these animals
in the gulf

What's really exciting is that
there are early indications

that this may be the place that
blue whales come with their calves

For our cameraman, Rick Rosenthal,
it was a unique opportunity

to get rare footage of a blue whale
mother with its young

Marylee, we're just got a...
