There is a force sufficiently powerful
to move the oceans of this world

lt is a force, not of this earth

The moon is large enough
to generate gravity

and with sufficient force
to pull on the earth,

two hundred and thirty
thousand miles away

As the moon orbits the earth its gravity
sweeps across the face of our planet

lts power drags a great bulge of oceanic
water in its wake

- the rising tide

The River Amazon in Brazil

On some special days the
gravitational forces

of the moon and the sun pull together
- to extraordinary effect

A growing tidal wave from the ocean
is being forced two hundred miles inland

This is a tidal bore

Fortunately tidal bores are rare,

but the moon does create strong
tides out in the world's oceans,

on every day of the year

The Bay of Fundy, in Nova Scotia

The tides here are
the largest in the world

and have a profound effect on marine life,
creating a rich feeding ground

A feast that attracts some of the
largest diners on the planet

Humpback whales

But they are not the biggest
threat to the herring

These are finback whales

At seventy tonnes - the second
largest animal on earth,

but so beautifully streamlined that
it is the fastest of the great whales

This combination of
speed and immense size

makes the finback a voracious
hunter of schooling fish

The Bay of Fundy can attract so many fish,
that during the summer,

as many as five hundred of these
magnificent whales hunt here every day

The feeding is best where
the tides run strongly

So the whales move
further into the bay,

following tidal rips
and searching for fish

Their movements are closely watched
by flocks of Cory Shearwaters

As the whales dive down
toward the fish

- more and more birds gather,
anxious to pick up scraps

The flowing tide may provide
a feast for the whales,

but before long it will turn

ln just six hours,
one hundred billion tonnes of water

will flow out of the bay

The sea level falling
by as much as 1 5 metres
