Argentina - April 15th, 2012

Opaque tan sediments color the waters of the Rio de la Plata Estuary, stretching between Argentina (below) and Uruguay (above). The city of Buenos Aires can be observed on the southern shores of the estuary, while Montevideo can be observed on the northern shores. Both cities appear as grey areas against the surrounding green terrain.

Slightly darked sediments also frame the shores of Samborombón Bay, located at the Rio de la Plata’s mouth, about 160 kilometres (99 mi) southeast of Buenos Aires. The bay receives the Salado and Samborombón Rivers. As the sediments from these rivers and the Rio de la Plata diffuse into the Atlantic Ocean, they become greenish in color. Further offshore, however, near the right edge of the image, is a green stain caused by phytoplankton growth.
