Sediments in Río de la Plata Estuary by Buenos Aires

34.6S 58.3W

June 20th, 2012 Category: Rivers, Sediments

Argentina - June 5th, 2012

Despite some dotted cloudcover, dense tan sediments in the Río de la Plata river and estuary are clearly visible in this image. The river is formed by the confluence of the Uruguay River and the Paraná River on the border between Argentina and Uruguay. The coasts of the Río de la Plata are the most densely populated areas of Argentina and Uruguay. Here, although the Uruguayan capital of Montevideo is blotted out by clouds, the Argentine capital of Buenos Aires is clearly visible on the southern shores of the estuary.

Argentina - April 17th, 2012

Sediments color two areas of Argentina’s eastern shoreline: visible in the upper right quadrant are tan sediments in the Rio de la Plata Estuary, near Buenos Aires, and visible further down the coast to the southwest are sediments near Bahía Blanca. Also visible near Bahía Blanca, but further offshore, are two small, teal colored phytoplankton blooms. Some sediments and/or phytoplankton can also been seen at the lower left, trailing off the Valdes Peninsula.

Buenos Aires on Shores of Rio de la Plata Estuary, Argentina

Argentina and Uruguay - January 1st, 2012

Buenos Aires is visible near the center of this image as a grey area along the Rio de la Plata estuary. It is the capital and largest city of Argentina, and the second-largest metropolitan area in South America, after São Paulo. It is located on the western shore of the estuary of the Río de la Plata, on the southeastern coast of the South American continent. The city of Buenos Aires lies in the pampa region, except for some zones that were all built on reclaimed land along the coasts of the river.

The Rio de la Plata is the heavily sedimented river and estuary formed by the confluence of the Uruguay River and the Paraná River on the border between Argentina and Uruguay. It is a funnel-shaped indentation on the southeastern coastline of South America, about 290 kilometres (180 mi) long. The Río de la Plata widens from about 2 kilometres (1.2 mi) at the inner part to about 220 kilometres (140 mi) at its mouth. It forms part of the border between Argentina and Uruguay, and its coasts are the most densely populated areas of both countries.

Paraná and Uruguay Rivers Flowing from Misiones to Buenos Aires, Argentina

26.9S 54.4W

October 5th, 2011 Category: Rivers, Sediments

Argentina - September 21st, 2011

Argentina’s Misiones Province is demarcated by the darker green region in the upper right quadrant. The province is surrounded by Paraguay to the northwest, Brazil to the north, east and south, and Corrientes Province of Argentina to the southwest.

The Misiones plateau includes a part of Brazil across the border. The province is surrounded by three big rivers including the Paraná, Uruguay and Iguazú. Following the Paraná and Uruguay Rivers southward, one comes to their convergence, forming the Rio de la Plata Estuary.

Tan sediments from the rivers give the estuary’s waters a muddy appearance. The city of Buenos Aires can be observed on its southwestern shores, with Montevideo visible across the water to the northeast.

Sediments by Buenos Aires, Montevideo and Bahia Blanca, Argentina and Uruguay

Argentina and Uruguay - December 14th, 2010

Sediments spill forth from the Rio de la Plata estuary, passing the cities of Buenos Aires, Argentina (grey area on the lower banks) and Montevideo, Uruguay (grey area on the upper banks).

Sediments can also be seen near the city of Bahía Blanca, further down the coast (bottom center). Visible even further to the south in the full image is the Valdes Peninsula. Of note offshore is a faint phytoplankton bloom, the remnants of one observed earlier (click here for previous article).

Finally, moving back to the north, the Mar Chiquita can be observed in the upper left corner. It is a salt lake whose waters appear mostly green.
