The following pictures were taken in November 2007 on the coast at Yamba in New South Wales, Australia.

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.

The foam was so thick it came all the way up to the surf club "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.

Children play among all the foam which was been whipped up by cyclonic conditions .
