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.

This orthorectified wide-swath ASAR image shows the city of Porto Alegre, in the Brazilian State of Rio Grande do Sul. The city is situated by the shores of the freshwater Lagoa dos Patos, the second largest lagoon in Latin America and the biggest in Brazil. It is 174 miles (280 km) long, has a maximum width of 44 miles (70 km), and a total area of 3,803 sq. mi. (9,850 km).

Porto Alegre, appearing as a bright white area near the northern shores of the lagoon, is the tenth most populous municipality in Brazil and the capital city of the country’s southernmost state, Rio Grande do Sul. The city lies on the eastern bank of the Guaíba River estuary, where five rivers converge to form the Lagoa dos Patos.

The large lagoons known as Lagoa dos Patos and Lagoa Mirim are located near the Atlantic Coast of Brazil and Uruguay. Lagoa Mirim, also called Laguna Merín, is the further south of the two, located partially in both countries. The lagoon is mostly a uniform brownish grey color.

Lagoa dos Patos, on the other hand, meaning Lagoon of the Ducks, is the larger of the two, and located entirely within Brazil. It appears mostly greenish in color here, although upon opening the full image, some dark brown, tan, and dark green areas can also be observed. The city of Porto Alegre can be seen on its northern shores.
