Argentina and Uruguay – January 26th, 2013

The Río de la Plata is a complex water system that connects the del Plata Basin with the Atlantic Ocean. Streams flow from southwest to northeast discharging along the coast of the Río de la Plata Estuary.

Its southwestern coastal sector holds densely populated areas (here, the city of Buenos Aires is visible as a large grey area) with tributaries running across them, which are also receptors of different discharges of pollutants. Human activity is the cause of serious pollution of surface waters, sediments and soils due to point and non-point industrial, agricultural and urban sources.

Results of recent studies show high burdens of different chemical loads in tributaries such as Riachuelo and Canal Oeste. Concentration levels of pollutants are within ranges expected to produce biological effects on aquatic biota, pointing to the need for mitigation interventions (click here for more information).

Lagoons and Estuaries Along Coast of South America

Argentina – October 26th, 2012

Sediments can be seen in various bodies of water along the coast of South America. In the lower left quadrant is the Río de la Plata Estuary, between Argentina (minimally visible at the left edge) and Uruguay. The city of Montevideo can be seen along the shoreline by the estuary. Moving northeastward up the coast, Laguna Merín (or Lagoa Mirim) appears filled with greyish brown sediments, while Lagoa dos Patos, further up the coast in Brazil, shows sediments with a more reddish hue.

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 - June 6th, 2010

Argentina has an area of 1,073,520 sq mi (2,780,403 sq km) and a population (2009 est.) of about 40,276,000. The capital is Buenos Aires, visible near the center of the image along the lower shores of the Rio de la Plata estuary (neighboring country Uruguay is visible along the upper shores). Dense sediments flow out of the estuary and into the Atlantic Ocean.

Argentina can be divided into four general regions: the North, the Pampas, Patagonia, and the Andes Mountains. The subtropical plains in the northeast are divided by the Paraná River into Mesopotamia to the east and Gran Chaco to the west and north.
