Uruguay and Brazil – July 9th, 2012

Sediments and phytoplankton growth give the Lagoa dos Patos, in southern Brazil’s state of Rio Grande do Sul, an array of different colors. Tan sediments can be seen entering the lagoon in the northern part, near the city of Porto Alegre, while reddish brown sediments enter below the middle by the upper shoreline, near the city of São Lourenço do Sul. The southern part of the lagoon is more green in color. Further south, greyish tan sediments can be observed in Lagoa Merim (Laguna Merín), on the Brazil-Uruguay border. Sediments also line the Atlantic shoreline between the two lagoons.
