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, and originated in the Magallanes Region in Chile. 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.
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 largest freshwater lake in Argentina, with a surface area of 1,415 km2 (546 sq mi) and a maximum width of 20 mi (32 km). The lake's waters have an average depth of 155 m (509 ft), with a maximum depth of 719 m (2,359 ft). The deepest point of the lake is situated; in the end of its narrow north-northwestern arm. In front of the retreating Upsala Glacier. This depth was discovered during a survey in, 2001. The south-southwestern arm ends in front of the, Perito Moreno Glacier. The glaciers debouches into the lake at these sites. Making "trenches" in the bedrock. The lake reaches, astonishing 541 m (1,775 ft) below mean sea level.
The Holocene glacial retreat is a geographical phenomenon that involved the global retreat of glaciers (deglaciation) 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, also called Calafate, is a city in the Argentine province of Santa Cruz, in Patagonia. It is located on the southern border of Lago Argentino, in the southwest part of the province. The name of the city is also the name of a small bush, with yellow flowers and dark-blue berries, that is very commonly seen in the region—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 is a well-documented effect of climate change. The retreat of mountain glaciers provide evidence for the rise in global temperatures since the late 19th century. Examples include mountain glaciers in western North America, Asia, the Alps in central Europe, and tropical and subtropical regions of South America and Africa. Since glacial mass is affected by long-term climatic changes, e.g. precipitation, mean temperature, and cloud cover, glacial mass changes are one of the most sensitive indicators of climate change. The retreat of glaciers is also a major reason for sea level rise. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 years from 1993 to 2018 were likely 5500 gigatons, or 210 gigatons per year.
Lautaro is an active subglacial stratovolcano located in Chilean Patagonia, in the northern part of the Southern Patagonian Ice Field. Its summit rises roughly 2,400 m (7,900 ft) above the average surface of the ice cap plateau.
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, Chile, 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.
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.
Onelli Bay is a bay of Argentino Lake, Santa Cruz Province, Argentina, within Los Glaciares National Park. It is made up of a Patagonian forest and a tributary of Lake Onelli flows into it, into which the Onelli, Agassiz, Bolados and Heim Glaciers also flow.
