First report of a surf zone diatom accumulation in the Eastern South Pacific: Aulacodiscus kittonii Arnott ex Ralfs (Bacillariophyta) as the dominant and exclusive species

The so-called "surf diatoms" constitute a small group of species that are present with great abundance in the surf zones of some sandy beaches where often the accumulations are dominated only for one of these species. They adhere to air bubbles generated by wave action forming green or bro...
