海洋岛屿 8

And it's not just love that's in the air.

At these southerly latitudes

ocean winds bring rain six-and-a-half days out of seven.

And when it doesn't rain,it snows.

It couldn't be more different

from the cliched image of a South Pacific island.

But surprisingly, what makes Macquarie so rich in wildlife

also benefits other islands in the tropical South Pacific

thousands of miles away.

Macquarie's penguins and seals depend on a cold

nutrient-rich current and that doesn't stop here.

Powered by the strongest winds in the world

the current continues east until it hits the tip of South America

where it's driven northwards.

Over 8,000 miles later

the cold current reaches the equator

and a remote archipelago.

The water has warmed up on the journey north

but it's still cold and nutrient rich.

This has allowed some animals to live here

which you wouldn't normally find this close to the equator.
