Argentina – April 18th, 2013

Plumes of smoke from fires can be seen in northern Argentina, northeast of the Mar Chiquita (lower left), in the province of Córdoba, and west of the Paraná River (right). In the full image, the precise locations of the fires are indicated by square markers.

Fires North of Reservoir of Yacyretá Dam, Paraguay

Paraguay – April 17th, 2013

Multiple plumes of smoke from fires in Paraguay can be seen north of the reservoir created by the Yacyretá Dam. The dam, also known as the Jasyretâ-Apipé Hydroelectric Power Station, is a dam and hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé in the Paraná River, between the Argentine Province of Corrientes and the Paraguayan City of Ayolas.

Bodies of Water and Phytoplankton, Argentina

Argentina – March 27th, 2013

Several bodies of water can be seen in this image of Argentina. In the upper left quadrant is the Mar Chiquita, a salt lake in the province of Córdoba, southeast of the white salt flats of the Salinas Grandes. Flowing down from the top right quadrant are the Uruguay and Paraná Rivers, which converge to form the wide, sediment-filled estuary of the Río de la Plata. Continuing south down the coast, a phytoplankton bloom, possibly mixed with sediments, can be seen near the bottom edge.

Paraná Delta and Rio de la Plata Estuary, Argentina

Argentina – January 28th, 2013

The Paraná River runs through Brazil, Paraguay and Argentina, where it flows into another river called Río de la Plata. Through the Parana Delta and the Rio de la Plata estuary, the second major hydrographic basin of South America (La Plata Basin) drains to the Atlantic Ocean.

From a geologic perspective, the complex system of the delta and the estuary are considered a dynamic sedimentary geologic-hydrologic unit which has a vital relevance not only for the region -a high populated area with more than 22 million inhabitants- but also for the hydrology of South American continent. According to the Intergovernmental Panel on Climate Change, the Rio de la Plata, the Amazon and the Orinoco carry into the Atlantic Ocean more than 30% of the renewable freshwater of the world.

The Delta of the Paraná River is one of the largest coastal wetlands systems of Argentina, spreading over 320 km and covering a surface of 15000 km2. The Delta presents a variable width, from 18 Km up to 100 km, and according to landscape parameters and hydrologic regimes, it presents more than 10 landscape units distributed in 3 zones: Superior, Medium and Lower Delta. The Parana Delta is rich in biodiversity and natural resources and faces the pressures of urban growth and the consequences of climate changes. It is a natural capital which represents a valuable benefit for the human population due to the ecosystem’s goods and services.

The high sediment transportation rate of the Parana River turns the delta into a changing territory whose front is expanding towards the Rio de la Plata and it is expected to reach the coast of the city of Buenos Aires (visible here as a grey area on the shores of the estuary) in around 110 years. This future trend makes important to develop a study of the complete system taking into account the natural phenomenon, the relation with the dynamics of the urbanization processes and climate changes (click here for more information).

Wetlands of Esteros del Iberá, Argentina

Argentina and Paraguay- December 2nd, 2012

This image shows the Iberá Wetlands or Iberá Provincial Nature Reserve (in Spanish, Esteros del Iberá), a mix of swamps, bogs, stagnant lakes, lagoons, natural slough and courses of water in the center and center-north of the province of Corrientes, Argentina.

The Esteros are the second-largest wetlands in world after Pantanal in Brazil. They are of pluvial origin, with a total area 15,000 to 20,000 km². Iberá is also one of the most important fresh water reservoirs in the continent. Visible in the upper part of the image is a reservoir along the Paraná River, on the border with Paraguay.
