SEA FOAM: BUBBLES AT THE BEACH


Newscasts all over Australia and off shore aired footage of an extreme example of sea foam in  Queensland's Sunshine Coast at the end of January. Here is one broadcast that told the story.




As a great follow up CSIRO's Science by Email features a classroom activity and information on sea foam. Students and teachers can sign up for Science by Email here

And there is a great article by NOAA available online here that explains some of the more interesting facts around sea foam. 

"Seawater contains dissolved salts, proteins, fats, dead algae, and a bunch of other bits and pieces of organic matter. If you shake this glass of ocean water vigorously, small bubbles will form on the surface of the liquid. Sea foam forms in this way — but on a much grander scale — when the ocean is agitated by wind and waves. Each coastal region has differing conditions governing the formation of sea foams."  






A first hand experience with storm surf and storm foam is something to remember!
