Here is an interesting news.
Tsunami caused by earthquake in Chile causes suds on beaches along the California, including Hollywood Beach in Oxnard. The vast quantities of sea foam are unusual mix of weather and ocean conditions which are unstable in sedimentary layers, added to the large waves created by the massive Chilean earthquake. The spume is made from protein and fat molecules created by the breakdown of phaeocystis, microscopic sea creatures. Pollution is also said to affect the sea foam where too many nutrients in the water cause large colonies of phaeocystis to form.
