Glacial Retreat in Argentina

For the crew onboard the International Space Station daylight views of the Earth’s Southern Hemisphere offer fewer opportunities to observe and document land features with onboard cameras. However, South America’s Patagonian Ice Fields and glaciers in the far southern Andes mountains offer beautiful, dynamic features with frequent passes whenever weather conditions permit. On the afternoon of January 3, 2004, the crew took this view of the Upsala Glacier in Argentina. A worldwide retreat of glaciers was observed during the twentieth century and most of the Patagonia’s glaciers, including Upsala, were no exception.

Brüggen Glacier, Chile

Brüggen Glacier in southern Chile is the largest western outflow from the Southern Patagonian Ice Field and, unlike most glaciers worldwide, advanced significantly since 1945. From 1945 to 1976, Brüggen surged 5 km across the Eyre Fjord, reaching the western shore by 1962 and cutting off Lake Greve from the sea.

Northern Patagonian Ice Field, Chile

The Northern Patagonian Ice Field (NPIF), centered near 47°S, 73.5°W, is the smaller of two remnant ice masses crowning the Andes Mountains of lower South America. The NPIF is a vestige of an extensive ice sheet that covered much of Patagonia just over a million years ago. Today, with its glaciers largely in retreat and only an area of 4,200 sq km, it is still the largest continuous mass of ice outside of the polar regions.

Glaciers in the Tropics, but Not for Long

Though the mountains are located just south of the equator, their elevation is high enough and the air temperatures are cold enough to still support a few small areas of ice.
