Glaciar Perito Moreno (hereafter GPM; 50°30′S and 72°50′W) is a major outlet glacier from the South Patagonia Icefield. In contrast to most Patagonian glaciers, glaciological studies indicate that GPM has been advancing or remained stable during the 20th century. The advances periodically block Canal de los Témpanos creating an ice dam that impounds Brazo Sur–Rico arms of Lago Argentino, raising their elevations, until the water is released in a major outburst flood. Documentary evidence…

Stratigraphic signature of the Perito Moreno ice-dammings during the Little Ice Age (southern Patagonia, Argentina)

The spectacular water outburst occurring semi-periodically when the ice-dam formed by the external front of the Perito Moreno glacier collapses, is one of the most attracting events in the UNESCO

Patterns of Tree Establishment Following Glacier-Induced Floods in Southern Patagonia

Whereas tree establishment after large-scale disturbances such as fires, avalanches, and landslides have been documented for Patagonian forests, information on forest recovery following floods is

Late-glacial fluctuations of two southern Patagonia outlet glaciers revealed by high-resolution seismic surveys

Abstract Lago Argentino hosts various calving glaciers, among them the famous Perito Moreno. Whereas the onland late Pleistocene–Holocene glacial history is rather well constrained, the submerged

The submerged footprint of Perito Moreno glacier

Evidence of two subaqueous moraine systems both in the Canal de Los Témpanos and in the Brazo Rico are interpreted as the evidence of the most pronounced advance of Perito Moreno glacier during the mid-Holocene cooling event that characterized this sector of the Southern Hemisphere.

Depositional setting of the southern arms of Lago Argentino (southern Patagonia)

ABSTRACT Lago Argentino hosts a series of calving glaciers originating from the Southern Patagonian Icefield, the largest temperate ice cap of the southern hemisphere. Brazo Rico and Brazo Sur are

Overview of the ice-dam formation and collapse of Glaciar Perito Moreno, southern Patagonia, in 2003/04

A spectacular ice-dam rupture at Glaciar Perito Moreno (GPM), southern Patagonia, which occurred on 14 March 2004, was reported by Chinni and Warren (2004). Unfortunately, that correspondence

The 2004 outburst flood at Glaciar Perito Moreno, Argentina

The 2004 outburst flood at Glaciar Perito Moreno, Argentina Glaciar Perito Moreno (508280 S, 738020 W), with a surface area of 259 km, is one of the major eastern outlet glaciers of Hielo Patagónico

Freshwater calving and anomalous glacier oscillations: recent behaviour of Moreno and Ameghino Glaciers, Patagonia

Moreno Glacier has been consistently advancing during a period of general glacier retreat this century, and has repeatedly dammed an arm of Lago Argentino. The most recent episode of ice-dam failure

Glaciar Perito Moreno, Patagonia: climate sensitivities and glacier characteristics preceding the 2003/04 and 2005/06 damming events

Abstract Mass balance and climate sensitivity of Glaciar Perito Moreno (GPM), one of the main outlet glaciers of Hielo Patagónico Sur (southern Patagonia icefield), were investigated. Field

Dynamic behavior of Glaciar Perito Moreno, southern Patagonia

Frontal oscillations since the beginning of the 20th century are known at Glaciar Perito Moreno, an eastward outlet glacier of Hielo Patagónico Sur (southern Patagonia ice field). In 1900, the

Climatic significance of intra-annual bands in the wood of Nothofagus pumilio in southern Patagonia

Intra-annual bands occurred more frequently in the twentieth century than the late eighteenth and nineteenth centuries, and seems to be a response to the combination of a long-term warming trend and a significant decrease in precipitation recorded during the last 100 years in this region of southern South America.
