From sea foam appearing on the shores of Argentina

A thick layer of sea foam covered several beaches in the Argentinian city of Mar del Plata on Wednesday.
Young and old were seen enjoying it and taking pictures in an unusually thick layer of sea foam that covered the beaches of one of Argentina's major tourist cities in the middle of the summer season.
According to reports, the strange phenomenon is related to a mixture of waves with high concentrations of organic matter found on the Argentine Atlantic coast.
