Sea Foam

This is amazing. This happened in August 2007, when the Australian shoreline at Yamba, north of Sydney, was swallowed up by a layer of foam.

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.

  1. do those stupid people even know what they playing in. Dead secreted plant stuff, dead fish and whale sperm.


    Steve S Reply:

    Strictly speaking, we’re all made of dead plants, fish and, I would assume, some whale sperm. There’s no obvious reason that sea foam would be harmful to people.


  2. Yeah, I don’t think I’d be playing in that stuff. Probably has a nasty fishy odor to it.

    Reminds me of the end of the Ghostbusters movie, though…


  3. Seafoam is simply created by any sort of wave action, formed from bodies of diatoms and flagellates. Flagellates live in colonies surrounded by gelatinous polysaccharides, and the structure of this mucus makes it subject to foaming by wave action. The silica-shelled bodies of diatoms are smashed apart by waves, and the silica and oils from their bodies create foam structure. Seamfoam can be stable for hours to days, and tends to accumulate on beaches or drift on currents. In the sun it will turn brown or a greenish colour, leading many to think it is pollution. Seafoam is actually a great indicator of a healthy, productive ocean ecosystem, as there is a high density of phytoplankton in the water.


  4. That’s earth jizz
