December 24th, 2011 Category: Lakes, Rivers, Sediments

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 - August 16th, 2011

This image stretches across the Argentine province of Santa Cruz to Tierra del Fuego, shared by Chile and Argentina. Visible in the lower right corner is Mitre Peninsula, the easternmost part of Isla Grande de Tierra del Fuego.

The land to the east is snow-free, while that to the west, by the Andes Mountains, is snow-covered. Visible amidst the snow are three bright blue lakes: Lake O’Higgins/San Martín, Lake Viedma and Lake Argentino (from north to south).

The lake known as O’Higgins in Chile and San Martín in Argentina, is located in Patagonia, between the Aysén Region and the Santa Cruz Province. Its surface is of 1,058 km² at 250 metres above mean sea level, and has a shoreline length of 525 km. Viewed from above, the lake consists of a series of finger-shaped flooded valleys, of which approximately 554 km² are in Chile and 459 km² in Argentina.

Viedma Lake, approximately 50 miles (80 kilometers) long in southern Patagonia near the border between Chile and Argentina, is a major elongated trough lake formed from melting glacial ice. The Viedma Glacier measures 3 miles (5 kilometers) wide at its terminus at Lake Viedma.

Lago Argentino is a lake in the Patagonian province of Santa Cruz, Argentina. It is the biggest freshwater lake in Argentina, with a surface area of 1,466 km2 (566 sq mi) (maximum width: 20 mi (32 km)). It has an average depth of 150 m (492 ft), and a maximum depth of 500 m (1,640 ft).

Argentina - September 15th, 2010

The southern end of Argentina covers the left side of this image. Sediments can be seen by the coastline, particularly that of the province of Tierra del Fuego at the very bottom.

Further east, the Falkland Islands (or Islas Malvinas) can be observed amidst some patches of clouds. East Falkand (right) is cloud free, while West Falkland (left) is partially obscured. They are located 250 nautical miles (463 km; 288 mi) from the Argentine mainland.

Tierra del Fuego, Argentina and Chile

Argentina - October 6th, 2009

Tierra del Fuego (Spanish for “Land of Fire”) is an archipelago 73,753 km2 (28,476 sq mi) off the southernmost tip of the South American mainland, across the Strait of Magellan. The southern point of the archipelago forms Cape Horn.

Tierra del Fuego is shared by Argentina and Chile. More precisely, 18.507,3 km2 belongs to Argentina (38,57% of the region’s total surface), 29.484,7 km2 belongs to Chile (61,43% of total surface).

The climate in this region is very inhospitable. It is a subpolar oceanic climate (Köppen climate classification Cfc) with short, cool summers and long, wet, moderate winters. The precipitation averages 3,000 mm (118 in) a year.

Temperatures in Ushuaia hardly surpass 9 °C (50 °F) in summers and average 0 °C (30 °F) in winters. Snowfall can occur in summer. The cold and wet summers help preserve the ancient glaciers.

The southernmost islands possess subantarctic climate typical of tundra that makes the growth of trees impossible. Some areas in the interior have a polar climate.

Habitat Changes on the Falkland Islands

Argentina – January 29th, 2013

The Falkland Islands (Islas Malvinas) are located in the South Atlantic Ocean on a projection of the Patagonian Shelf about 310 miles (500 kilometres) east of the Patagonian coastline and about 280 miles (450 kilometres) north-east of the southerly tip of Tierra del Fuego, Argentina. The Falklands, which have a total land area of 4,700 square miles (12,173 square kilometres) and a coastline estimated at 2,200 miles (3,500 km)[92] comprise two main islands, West Falkland and East Falkland and about 776 smaller islands. The two principal islands are 140 miles (220 km) from east to west and 87 miles (140 km) from north to south. They are heavily indented by sounds and fjords and have many natural harbours. The two main islands are separated by the Falkland Sound.

There is little long-term data on habitat changes, so the extent of human impact to the islands is unclear. Vegetation such as tussac grass, fachine, and native box have been heavily impacted by introduced grazing animals. Virtually the entire area of the islands is used as pasture for sheep. Rats and Grey foxes have been introduced and are having a detrimental impact on birds that nest on the shores, as are feral cats. Many breeding birds similarly only live on offshore islands, where introduced animals such as cats and rats are not found. There is also an introduced reindeer population, which was brought to the islands in 2001 for commercial purposes. Twenty two introduced plant species are thought to provide a significant threat to local flora.
