October 12th, 2010 Category: Image of the day, Sediments

Argentina - September 21st, 2010

The coastline of the southernmost part of the Argentine province of Buenos Aires, near the city of Bahía Blanca (meaning “White Bay”) appears greenish due to sediments from the Naposta Stream. Some sediments can also be seen north of the Valdes Peninsula, situated at the bottom left edge of the image.

Since the city of Bahía Blanca is located at the limit between Pampas and Patagonia, it is warm and more humid to the north and varies rapidly to the south, becoming drier. This change from Pampas to Patagonian steppes is evident in the image, as the northern parts appear greener and more fertile, while the southern parts appear browner and drier.

The green of the Pampas (above) gradually fades into the tan of Patagonia as one moves southward in this image of Argentina and parts of Chile (far left). The Valdes Peninsula stands out along the coastline to the right.

The peninsula is located along the Atlantic coast in the Viedma Department in the north east of Chubut Province, Argentina. Its surface area is about 3,625 km². The nearest large town is Puerto Madryn, and the only town on the peninsula itself is the small settlement of Puerto Piramides. There are also a number of estancias, where sheep are raised.

Most of the peninsula is barren land with some salt lakes. It is an important nature reserve which was listed as a World Heritage Site by UNESCO in 1999. The coastline is inhabited by marine mammals, like sea lions, elephant seals and fur seals. Southern right whales can be found in Golfo Nuevo and Golfo San José, protected bodies of water located between the peninsula and the Patagonian mainland. The inner part of the peninsula is inhabited by rheas, guanacos and maras, as well as a high diversity and range of birds.

Argentina and Chile - January 25th, 2010

The landscape of Argentina and Chile (far left) shows a greatly varied vegetation index in this FAPAR image. Patagonia appears white to light yellow, indicating a low presence of photosynthesis and vegetation covering.

Green to red areas, on the other hand, indicate a good to high presence of photosynthetic activity and vegetation. Here, such areas are visible in the Pampas, the fertile central plains of Argentina and the source of the country’s agricultural wealth, and central to southern Chile.

Central Chile experiences a Mediterranean climate and dominates in terms of population and agricultural resources, and southern Chile has a rainy temperate climate and is rich in forests and grazing lands.

Rosario, the largest city in the province of Santa Fe, Argentina, can be seen in the lower half of this image on the western shore of the Paraná River, about 300 km (187 miles) northwest of Buenos Aires. With 1,159,004 residents as of the 2001 census, it is the third largest city in Argentina by its population.

The city is located on a smoothly undulated plain typical of the Pampas, between 22.5 and 24.6 metres above mean sea level; the original settlement rests on the ravine on the right-hand shore of the Paraná, opposite a group of islands of the Paraná Delta which are partly in the jurisdiction of the province of Entre Ríos. The nearest city across the river’s 60 kilometer-wide flood plain (the Paraná Delta) is Victoria, Entre Ríos, linked to Rosario by the Rosario-Victoria Bridge.

The city is a major railroad terminal and the shipping center for northeastern Argentina. Ships reach the city via the Paraná River, which allows the existence of a 34-feet deep port. The Port of Rosario is subject to silting and must be dredged periodically.

Province of Buenos Aires, Argentina - November 7th, 2008

In this image we have a cloudless view of the  Province of Buenos Aires, Argentina. The Rio de la Plata is clearly visible thanks to the great number of sediments present.

We can also see part of Bahia Blanca, less affected by sediments but with a phytoplankton bloom, in the bottom center. West of Bahia Blanca, we can observe the terrain becoming less flat as it approaches the Sierra de la Ventana mountain range.

The province of Buenos Aires Province (Provincia de Buenos Aires) is the most populated province of Argentina. The province has a population of 13,827,203 (2001) and its capital is La Plata (694,253 inhabitants), 56 kilometers south of the city of Buenos Aires.

The city of Buenos Aires, located next to provincial territory, is an autonomous city and not part of the province.

The Buenos Aires province has an area of 307,571 km²; it is also the largest province of Argentina.

The landscape is mainly flat, with two low mountain ranges; Sierra de la Ventana (near Bahía Blanca) and Sierra de Tandil (Tandil). The highest point is Cerro Tres Picos (1.239 m) and the longest river is Río Salado (700 km).

As part of The Pampas the weather of the province is strongly influenced by the ocean, with hot summers and temperate winters. Humidity is high and precipitations are abundant and distributed over the year. The Western and Southwestern regions are dryer.
