Argentina – December 2nd, 2012

A beautiful mix of colors from sediments and algal growth can be seen in the Rio de la Plata Estuary, between Argentina (below, left) and Uruguay (above, right): many different hues including dark brown, tan, greyish brown, green and blue are all present. Visible on the Argentine side is the country’s capital city, Buenos Aires, appearing as a large grey area. Montevideo, the capital of Uruguay, is visible further east, on the upper banks.

Argentina and Uruguay – July 9th, 2012

Sediments diffusing into the Atlantic Ocean give intense coloring to the Rio de la Plata estuary, separating Argentina (left) and Uruguay (above). The sediments rushing into the estuary from the Paraná and Uruguay Rivers give its upper reaches a dark tan hue, which changes to opaque yet lighter tan near the mouth, before mixing with the waters of the Atlantic Ocean in beautiful greenish tones. Visible near the left edge, on the shores of the estuary, is the Argentine capital, Buenos Aires. Montevideo, the Uruguayan capital, can be seen near the right edge.

Argentina and Uruguay – June 25th, 2012

The Uruguay and Paraná Rivers and the sediments they carry join together in the upper left quadrant of this image to form the extremely silty Río de la Plata river and estuary on the border between Argentina and Uruguay. As the sediments flow through the 290 kilometre (180 mi) long funnel-shaped indentation of the estuary, they gradually diffuse into deeper waters approaching the Atlantic Ocean and become lighter in color. Visible on the shores of the estuary are Buenos Aires, the capital of Argentina (left), and Montevideo, the capital of Uruguay (right).

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.

Uruguay and Argentina - December 29th, 2011

This orthorectified wide-swath ASAR image shows the Rio de la Plata estuary, between Uruguay (above) and Argentina (below). The city of Buenos Aires, Argentina, can be observed as a large white area near the left edge, while Montevideo, Uruguay is visible near the image center and the city of Punta del Este, Uruguay, is visible near the right edge.

Buenos Aires is the capital and largest city of Argentina, and the second-largest metropolitan area in South America, after São Paulo. Montevideo is the largest city, the capital, and the chief port of Uruguay. It has an area of 530 square kilometres (200 sq mi) and extends 20 kilometres (12 mi) from west to east.
