The map published by the British Crown, as part of the documentation of the "Laudo of 1902", illustrates a clear demarcation line (from the Fitz Roy to the Stokes) to the east of the Southern Patagonian Ice Fields leaving most of the territory in question in the Chilean side (Santis, 1995:3–7). Date: 15 October 2017: Source: Own work Water At first light the group breaks camp and sets out towards the Marconi Glacier. Many glacier tongues showed significant annual “retreat” of their ice fronts, a familiar signal of climate change. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The Southern Patagonian Ice Field (Spanish: Hielo Continental or Campo de Hielo Sur), located at the Southern Patagonic Andes between Chile and Argentina, is the world's second largest contiguous extrapolar ice field.

The yellow stars represent field camps within the study area. From the air, initial exploration was conducted in 1928–29 by Gunther Plüschow after whom a glacier is named. Northern Patagonia is one of the world's last great expanses of wilderness, accessed by a gravel highway known as the Carretera Austral, completed in 1988.

This is not the first time the Patagonian ice sheet has experienced large-scale iceberg calving events. Nevertheless, some areas of the field remain largely unexplored A fluctuating ice sheet. [5][6][7][8] Gateway to Astronaut Photography of Earth. Fifty kilometers of the Chile–Argentina border, between Mount Fitz Roy and Cerro Murallón, remain undefined[2][3] on the ice field. An Ice Field is a large body of ice that forms at high elevation and is drained by smaller outlet glaciers. Storms that swirl into the region from the southern Pacific Ocean bring rain and snow (between 2 to 11 meters of rainfall per year), resulting in the buildup of the ice sheet. Geologists now know that ice tongues extended far onto the plains in the foreground, completely filling the great Patagonian lakes on repeated occasions. Nevertheless, some areas of the field remain largely unexplored. In 2006, the Argentine Instituto Geográfico Militar (IGM) (today Instituto Geográfico Nacional) edited a map without a note about the nondefined border but showed the Argentine claims as the official borderline. This grand panorama of the Southern Patagonia Ice Field was photographed by a crew member aboard the International Space Station (ISS) on a rare clear day in the southern Andes Mountains. Located on southern Chile’s Pacific coastline, Laguna San Rafael National Park is one of the most breathtakingly beautiful parts of the country and definitely warrants a visit if you have the chance. This tour gets up close and personal with several of the most famous glaciers in and around the Torres del Paine National Park, including Amalia, El Brujo, Bernal, Herman, and the Fiordo Calvo area. Flight Center, Rignot, E., Rivera, A., Casassa, G. (2003). A recent expedition revealed a new rift in Kilimanjaro’s northern ice field. Thickness and volume. Patagonia (Spanish pronunciation: [pataˈɣonja]) is a sparsely populated region at the southern end of South America, shared by Argentina and Chile.The region comprises the southern section of the Andes Mountains, lakes, fjords, and glaciers in the west and deserts, tablelands and steppes to the east. However, they also agreed that final demarcation and exact location of the line there would wait until completion of a detailed 1:50,000 scale map of the area and further negotiations.

Image of the Day Mount Fitz Roy is a distinct mountain located in the Southern Patagonian Ice Field in Patagonia. The image was taken by the Expedition 38 crew. NASA Goddard Space Due to their inaccessibility they are among the least researched volcanoes in Chile and Argentina. There are two known volcanoes under the ice field; Lautaro and Viedma. An important part of the ice field is protected under different national parks, such as the Bernardo O'Higgins and Torres del Paine in Chile, and the aforementioned Los Glaciares in Argentina. Scientific significance and data collection: The acceleration of glaciers on the Southern Patagonian Icefield (SPI) can be driven in two distinct ways: from the top-down, or the bottom-up (Figure 2a-e). The Patagonian ice cap is the largest non polar ice on earth, and the third glacier mass in size after Antartica and Greenland. The results of a survey by Romain Millan and others was published last year in the journal Geophysical Research. Wellington Island Wellington Island is an island west of Southern Patagonian Ice Field, Chile. It assessed the ice thickness and volume of the Northern and Southern Patagonian Ice-fields. It towers over the southern part of the Northern Patagonian Ice Field. Cerro Arenales is a heavily ice-covered stratovolcano located in the Aysén del General Carlos Ibáñez del Campo Region of Chile, within Laguna San Rafael National Park. Background imagery was collected from Landsat 8 on 17 July 2018 and 8 October 2018.

It was also a rare opportunity to see the Southern Patagonian Ice Fields, which sounded super awesome. After Chilean diplomatic protests, the Argentine government withdrew the map and urged Chile to expedite the demarcation of the international border that had already been established by both countries in the 1881 treaty. The five dramatic Patagonian provinces stretch from the ice fields and granite peaks of the Andes mountains to the rugged Atlantic coast, where southern right whales gather to breed. Dense temperate rainforests cover the western coast, whereas the eastern plains are flat, vast, and arid. Caption by M. Justin Wilkinson, Jacobs at NASA-JSC. The GREEN BOX is … Harding Icefield, Kenai National Wildlife Refuge. Later, in 1998, both governments agreed that the line would run along the high peaks and watershed (as specified in their 1941 treaty) northward from Cerro Murallón to a point on a line of latitude due west of "Section B" that was specified in the 1998 agreement a few km southwest of Mt. World of Change. Isla Little Wellington On 1 August 1991 the governments of Chile and Argentina agreed on a borderline, but the agreement was never ratified by the Argentine parliament. The findings … Snow and Ice Fitz roy. The Southern Patagonian Ice Field (Spanish: Hielo Continental or Campo de Hielo Sur), located at the Southern Patagonic Andes between Chile and Argentina, is the world's second largest contiguous extrapolar ice field. This number becomes more meaningful when compared with the rate in the last five years of the study (1995-2000): an average of 38.7 cubic kilometers per year. However, many in Chile consider the border to have been established by the "Laudo of 1902," which was an agreement signed "to perpetuity" by both countries under British tutelage. Argentina (...) we have an agreement signed in 1998, which establishes that we are setting Day 3: Marconi Pass – Southern Patagonian Ice Field Entrance. The Patagonian Ice Field forms the largest mass of ice in the Southern Hemisphere. The RED BOX is Torres del Paine National Park. and to a decrease of the precipitation on the Pacific Ocean side of the ice field by as much as 1.4 m a-1 (Rosenblüth and others, 1995). "[12] An ice field (also spelled icefield) is a large area of interconnected glaciers, usually found in a mountainous region.
