Pollution Issues Affecting Río de la Plata Estuary, Argentina – February 16th, 2013

34.6S 58.3W

February 16th, 2013 Category: Image of the day, Rivers, Sediments

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).

Sun Glint on Rio de la Plata Estuary and Rincón del Bonete Lake, Argentina and Uruguay – December 15th, 2012

34.8S 57.1W

Argentina – December 13th, 2012

Sun glint causes the waters of the Rio de la Plata Estuary and the Rincón del Bonete Lake (upper right) to have a silvery color. The estuary is formed by the confluence of the Uruguay and Paraná Rivers, and it is located between Argentina and Uruguay. The Rincón del Bonete Lake is the largest body of fresh water in Uruguay. It is an artificial lake formed by a dam on the course of Río Negro. It was constructed in 1945 and has a surface of about 1,240 square kilometres (480 sq mi).

Green and Tan Sediments in Rio de la Plata Estuary – July 11th, 2012

35S 56.7W

July 11th, 2012 Category: Image of the day, Rivers, Sediments

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.

Sediments and Phytoplankton Trail by Rio de la Plata Estuary – July 7th, 2012

Argentina – July 5th, 2012

Dark tan sediments from the Uruguay and Paraná Rivers fill the Rio de la Plata Estuary; darker tan sediments can also be observed lining Samborombón Bay, the crescent-shaped bay to the southeast. A greenish trail is also visible in the Atlantic in an almost diagonal line from the shores of Buenos Aires province, due northeast, towards Uruguay. This trail is likely caused by sediments and phytoplankton growth around them, as they are rich in nutrients.

Sediments from the Uruguay and Paraná Rivers in Rio de la Plata Estuary, Argentina and Uruguay – July 2nd, 2012

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).
