Brackish Tan Waters of Lagoa dos Patos, Brazil30S 51.2W
Lagoa dos Patos is a large lagoon located in the state of Rio Grande do Sul, near the coast of southern Brazil. A sandbar of about 5 miles (8 kilometers) wide separates it from the Atlantic Ocean, although the Rio Grande at its southern end forms an outlet to the ocean. Here, the lagoon’s brackish waters appear tan in color.
Partially visible to the south is Lagoa Mirim, to which Lagoa dos Patos is connected by the navigable São Gonçalo Channel. Upon opening the full image, the Paraná River can be seen flowing vertically down the left side, marking the border between Brazil and Argentina.
