Lakes and Steppes of Argentine Patagonia

38.9S 68W

April 8th, 2012 Category: Lakes, Rivers

Argentina - March 31st, 2012

The Neuquén (above) and Limay (below) rivers, which converge just below the image center, are flanked by green vegetation, while most of the rest of the region shows the tan steppes characteristic of Argentine Patagonia.

Several artificial reservoirs can be observed near the joining of the rivers: the largest, created by El Chocón Dam, is turquoise from sediments in its eastern section. To the north are two lakes that form part of the Cerros Colorados Complex; the western one of the pair is slightly more green in color.

Argentine Coast from Bahía Blanca to Tierra del Fuego

Argentina - December 22nd, 2011

Sediments can be observed off the Atlantic Coast of Argentina, near the city of Bahía Blanca (upper right). The coastline further south appears mostly sediment free, with the exception of a greenish tinge around the Valdés Peninsula. The full image stretches southward all the way to Tierra del Fuego.

Visible further inland are several lakes in the province of Neuquén. They lie near the confluence of the Neuquén River (above) and the Limay River (below). Also located at their confluence is the city of Neuquén.

Argentina - November 15th, 2011

This orthorectified image shows Nahuel Huapi Lake, located in the lake region of northern Patagonia between the provinces of Río Negro and Neuquén, in Argentina. The lake depression consists of several glacial valleys carved out along faults and Miocene valleys that were later dammed by moraines.

Nahuel Huapi lake, located within the Nahuel Huapi National Park, has a surface of 529 km2 (204 sq mi), rests 2,510 feet (770 m) over the sea level, and has a maximum measured depth (as of 2007) of 1,437 feet (438 m).

Two Ash Clouds from Puyehue Volcano Over Argentine Patagonia – August 14th, 2011

41.3S 68.8W

August 14th, 2011 Category: Volcanoes

Argentina and Chile - August 13th, 2011

Hanging in the air over Patagonia in mid-August is ash from the 2011 Puyehue volcanic eruption, which began in early June. The ash seems to be blowing in a generally northeasterly direction.

The two most evident ash clouds are visible south of a cluster of lakes in Neuquén (below image center) and west of Bahía Blanca (upper right quadrant).

The Pampas and Sediments Near Bahía Blanca, Argentina

37S 64.1W

July 6th, 2011 Category: Sediments

Argentina - June 17th, 2011

Sediments line the coast near Bahía Blanca, Argentina, giving the waters there a greenish tinge. While the land near the shore and in the upper right quadrant is part of Buenos Aires Province, that in the upper left quadrant is part of La Pampa province, and that to the lower left is in Neuquén province.

Situated in the middle of the pampas, the low, flat steppe receives 500 mm of rain a year, diminishing towards the West. The low humidity and temperate weather result in high contrast in temperature between day and night, which is reflected in the vegetation of the region.
