Cappuccino Coast Richard Shears – Daily Mail.co.uk August 28, 2007
It was as if someone had poured tons of coffee and milk into the ocean,
then switched on a giant blender. Suddenly the shoreline north of Sydney
were transformed into the Cappuccino Coast. Foam swallowed an entire
beach and half the nearby buildings, including the local lifeguards'
centre (right), in a freak display of nature at Yamba in New South Wales.
One minute a group of teenage surfers were waiting to catch a wave,
the next they were swallowed up in a giant bubble bath.
The foam was so light that they could puff it out of their hands and
watch it float away. It stretched for 30 miles out into the Pacific
in a phenomenon not seen at the beach for more than three decades. Scientists
explain that the foam is created by impurities in the ocean, such as
salts, chemicals, dead plants, decomposed fish and excretions from seaweed.
All are churned up together by powerful currents which cause the water
to form bubbles.
These bubbles stick to each other as they are carried below the surface
by the current towards the shore. As a wave starts to form on the surface,
the motion of the water causes the bubbles to swirl upwards and, massed
together, they become foam. The foam "surfs" towards shore until the
wave "crashes", tossing the foam into the air. "It's the same effect
you get when you whip up a milk shake in a blender," explains a marine
expert. "The more powerful the swirl, the more foam you create on the
surface and the lighter it becomes." In this case, storms off the New
South Wales Coast and further north off Queensland had created a huge
disturbance in the ocean, hitting a stretch of water where there was
a particularly high amount of the substances which form into bubbles.
As for 12-year-old beachgoer Tom Woods, who has been surfing since he
was two, riding a wave was out of the question. "Me and my mates just
spent the afternoon leaping about in that stuff," he said. "It was quite
cool to touch and it was really weird. It was like clouds of air - you
could hardly feel it." http://www.dailymail.co.uk/pages/live/articles/news/worldnews.html?in_article_id=478041&in_page_id=1811
