Los Glaciares National Park is a federal protected area in Santa Cruz Province, Argentina.
Father Alberto Maria de Agostini born in Pollone, Piedmont was an Italian missionary of the Salesians of Don Bosco order as well as a passionate mountaineer, explorer, geographer, ethnographer, photographer and cinematographer.
The Perito Moreno Glacier is a glacier located in Los Glaciares National Park in southwest Santa Cruz Province, Argentina. It is one of the most important tourist attractions in the Argentine Patagonia.
Tronador is an extinct stratovolcano in the southern Andes, located along the border between Argentina and Chile, near the Argentine city of Bariloche. The mountain was named Tronador by locals in reference to the sound of falling seracs. With an altitude of 3,470 metres (11,380 ft), Tronador stands more than 1,000 m above nearby mountains in the Andean massif, making it a popular mountaineering destination. Located inside two national parks, Nahuel Huapi in Argentina and Vicente Pérez Rosales in Chile, Tronador hosts a total of eight glaciers, which are currently retreating due to warming of the upper troposphere.
Viedma Lake is a Patagonian lake in the province of Santa Cruz, Argentina, situated near its border with Chile. Measuring approximately 50 miles in length, it is a major elongated trough lake formed from melting glacial ice. Viedma Lake is the second largest perennial lake located entirely within Argentina.
The Northern Patagonian Ice Field, located in southern Chile, is the smaller of two remnant parts in which the Patagonian Ice Sheet in the Andes Mountains of southern South America can be divided. It is completely contained within the boundaries of Laguna San Rafael National Park.
An ice stream is a region of fast-moving ice within an ice sheet. It is a type of glacier, a body of ice that moves under its own weight. They can move upwards of 1,000 metres (3,300 ft) a year, and can be up to 50 kilometres (31 mi) in width, and hundreds of kilometers in length. They tend to be about 2 km (1.2 mi) deep at the thickest, and constitute the majority of the ice that leaves the sheet. In Antarctica, the ice streams account for approximately 90% of the sheet's mass loss per year, and approximately 50% of the mass loss in Greenland.
Lago Argentino is a lake in the Patagonian province of Santa Cruz, Argentina, at 50°2′S72°4′W. It is the biggest freshwater lake in Argentina, with a surface area of 1,415 km2 (546 sq mi). It has an average depth of 150 m (492 ft), and a maximum depth of 500 m (1,640 ft).
The Holocene glacial retreat is a geographical phenomenon that involved the global deglaciation of glaciers that previously had advanced during the Last Glacial Maximum. Ice sheet retreat initiated ca. 19,000 years ago and accelerated after ca. 15,000 years ago. The Holocene, starting with abrupt warming 11,700 years ago, resulted in rapid melting of the remaining ice sheets of North America and Europe.
El Calafate is a city in Patagonia, Argentina. It is situated on the southern border of Lake Argentino, in the southwest part of the Santa Cruz Province, about 320 kilometres (200 mi) northwest of Río Gallegos. The name of the city is derived from a little bush with yellow flowers and dark blue berries that is very common in Patagonia: the calafate ; the word comes from the word calafate, which is Spanish for 'caulk'.
The lake known as O'Higgins in Chile and San Martín in Argentina is located around coordinates 48°50′S72°36′W in Patagonia, between the Aysén del General Carlos Ibáñez del Campo Region and the Santa Cruz Province.
The Southern Patagonian Ice Field, located at the Southern Patagonic Andes between Chile and Argentina, is the world's second largest contiguous extrapolar ice field. It is the bigger of two remnant parts of the Patagonian Ice Sheet, which covered all of southern Chile during the last glacial period, locally called the Llanquihue glaciation.
The retreat of glaciers since 1850—affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, total global glacial losses were likely 5500 gigatons over 1993–2018.
O'Higgins Glacier is a glacier located in Bernardo O'Higgins National Park, Chile. It is one of the principal glaciers of the Southern Patagonian Ice Field. The summit of the active Lautaro volcano is the top of the accumulation zone of the glacier. The bulk of the glacier is part of the icefield plateau. It flows eastward into O'Higgins Lake and is about 2 km (1.2 mi) wide at the terminus.
Jorge Montt Glacier is a tidewater glacier located in the Aisén Region of Chile, south of the town of Caleta Tortel. It lies at the north end of the Southern Patagonian Ice Field, within Bernardo O'Higgins National Park. The mouth of Pascua River is located in the vicinity of the glacier calving front.
The tidewater glacier cycle is the typically centuries-long behavior of tidewater glaciers that consists of recurring periods of advance alternating with rapid retreat and punctuated by periods of stability. During portions of its cycle, a tidewater glacier is relatively insensitive to climate change.
Amalia Glacier, also known as Skua Glacier, is a tidewater glacier located in Bernardo O'Higgins National Park on the edge of the Sarmiento Channel. The glacier originates in the Southern Patagonian Ice Field. From 1945 to 1986, its terminus retreated 7 km (4.3 mi), being, along with the recession of the O'Higgins Glacier, the most dramatic retreat of the glaciers of the mentioned icefield during that period.
Flask Glacier, is a gently-sloping glacier, 25 nautical miles long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica. The lower reaches of this glacier were surveyed and photographed by the Falklands Islands Dependencies Survey (FIDS) in 1947. The entire glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–56, and mapped by the FIDS in 1957. It was named by the UK Antarctic Place-names Committee after the third mate on the Pequod in Herman Melville's Moby-Dick; or, The White Whale.
The Del Desierto lake or Lake of the Desert is a lake, located in the Lago Argentino Department, Santa Cruz Province, Argentina. The lake, located near the mount Fitz Roy and the O'Higgins/San Martín Lake, has been the subject of a territorial dispute between Argentina and Chile, escalating to a small battle on 6 November 1965 when 40 to 90 members of the Argentine Gendarmerie fought against four Chilean Carabineros resulting the lieutenant Hernán Merino killed and a sergeant injured, both members of Carabineros, the dispute was solved favourably for Argentina in 1994 with an arbitration.
Almut Iken was a German glaciologist most noted for her work on the role of basal meltwater in subglacial motion. In 2011, she was awarded the Seligman Crystal award from the International Glaciological Society and remains the only female recipient.
