Sea Foam

This is a natural process occurring in especially big seas, where plankton and other small sea organisms are literally pulverised against the rocks of the shoreline, resulting in a very fine protein suspension in the sea which coats the air-bubbles created by the waves to create a stiff froth, just the same way as egg protein coats air bubbles to make meringue, and beer protein coats air bubbles to produce a head of foam in a beer glass. from viv.id.au/blog/20070827.871/sea-foam/
