Strong waves and wind injecting air into the ocean and the presence of dissolved organic matter can form sea foam. The organic matter is mostly made of dead phytoplankton. The protein from the phytoplankton gives the water enough surface tension to form bubbles. Surf and winds cause the bubbles to pile up in suds-like masses that are often blown up on the beach. Although this may look worrisome, it is a perfectly natural process that helps the ocean purify its self. Viewed under a microscope, sea foam contains the extraordinarily beautiful glass-like skeletons of the phytoplankton. 10/26/10. http://www.dfw.state.or.us/rr/marine/ Изменить
