Climate Change in Patagonia, Argentina

43.6S 69.2W

March 22nd, 2013 Category: Climate Change

Argentina – March 21st, 2013

Most focus on climate change in Argentina has been in the north, where impacts are more noticeable. However, new studies also show how changes in the south, particularly in the Patagonian province of Chubut, are also likely to be significant.

Increasing temperature and decreasing rainfall in northwest Chubut are shifting the patterns of agricultural viability. Predominant patterns of cattle and sheep farming are likely to face increasing shortages of dry season grazing. Natural forests and existing and planned plantations are also likely to face increasing aridity—exacerbating the risk of dieback, forest fires and pest and disease outbreaks.

Water shortage is likely to become an increasingly pressing concern—especially with the heavy reliance on hydropower, major development plans for irrigated agriculture and forestry, heavy technological demands from the petrochemical industry for water pressure to drive oil extraction, and the importance of aquatic environments for regional tourism (click here for more information).

Argentina – November 4th, 2012

A green and blue phytoplankton bloom continues to flourish off the coast of Argentine Patagonia (click here for previous images of the bloom). Also visible here is some blue phytoplankton growth in the San Matías Gulf (upper left), an inlet of the Atlantic Ocean bordered by the Río Negro Province to the north and west, and the Valdes Peninsula of the Chubut Province to the south.

Sediments in San Jorge Gulf and Along Argentine Coastline

Argentina - July 23rd, 2011

Sediments line the coastline of Argentina by the provinces of Chubut and Santa Cruz. The large, semi-circular indentation is the San Jorge Gulf (Golfo San Jorge), a bay in southern Patagonia that opens to the Atlantic ocean. Its shoreline spans both of the aforementioned provinces.

The gulf measures approximately 142 miles (229 km) at its mouth and covers approximately 39 square kilometres (15 sq mi). It is located between Cape Dos Bahías and Cape Tres Puntas. Due to its geography, more than 70% of the gulf’s basin is between 70 metres (230 ft) and 100 metres (328 ft) deep. To the south it is about 50 metres (164 ft) 60 metres (197 ft) deep and in the north 90 metres (295 ft).

Visible in the lower right quadrant are the Falkland Islands (Islas Malvinas), an archipelago in the South Atlantic Ocean, located about 250 nautical miles (290 mi; 460 km) from the coast of mainland South America.

Argentina - February 23rd, 2010

This image of Argentina includes the provinces of Neuquén (upper left), Río Negro (upper right) and Chubut (lower half). Neuquén is located at the northern end of Patagonia. The province’s southeastern limits are set by the Limay River, facing the Río Negro Province.

There are two main distinctive landscapes; the mountainous fertile valleys with forest on the West, and the arid plateau with fertile land only near the basins of the rivers on the East, mainly the Limay River and Neuquén River.

Río Negro is also located at the northern edge of Patagonia. The main water source at the arid plains that cover most of the province is the Río Negro River, in whose valley most of the settlements and farms are located. The over 600 km of the Rio Negro’s valley are divided in Alto Valle (West), Valle Medio (center) and Valle Inferior (East).

Finally, Chubut is situated in the southern part of Argentina between the 42nd parallel south (forming the border with the Río Negro Province) and the 46th parallel south. The Andes range, partially visible in the lower left corner, separates the province from Chile.
