Brazil, Uruguay, Argentina – April 6th, 2013

Several bodies of water can be observed in this image of southern Brazil, Uruguay and Argentina. Near the coast are two lagoons: Lagoa dos Patos, in Brazil, and Lagoa Merim/Laguna Merín, shared by Brazil and Uruguay. There is a strong presence of sediments in both lakes.

In the upper left quadrant of the image are the Esteros del Iberá, or Iberá Wetlands, a mix of swamps, bogs, stagnant lakes, lagoons, natural slough and courses of water in the center and center-north of the province of Corrientes, Argentina. The Esteros are the second-largest wetlands in world after Pantanal in Brazil. They are of pluvial origin, with a total area 15,000 to 20,000 km². A fire can be seen near this wetlands area, releasing a white plume of smoke towards the south.

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.

Argentina, Paraguay, Uruguay, Brazil - May 13th, 2012

This image of South America stretches across Argentina, Paraguay, Uruguay and Brazil. The Argentine border is basically demarcated by the Uruguay River, flowing down from the upper part of the image and joining with the Paraná River in the lower left quadrant to create the sediment-filled Rio de la Plata Estuary. The city of Buenos Aires is visible on the lower shores of the estuary.

In the upper part of the image, the outline of the Argentine province of Misiones appears dark green, in contrast with the surrounding terrain of Brazil (to the northeast) and Paraguay (to the northwest). Visible along the Paraguay border is the lake created by the Yacyretá Dam, a dam and hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé on the Paraná River, between the Argentine Province of Corrientes and the Paraguayan City of Ayolas.

Finally, visible in the lower right quadrant, by the Uruguay-Brazil border, are two large, sediment-filled lagoons: Laguna Merín (Lagoa Merim), shared by the two countries (below), and Lagoa dos Patos, located entirely in Brazil (above).
