In 1958, a Russian airplane navigator named Robinson was making his landing approach at the newly opened Vostok research station when he noticed a large, flat, oval depression «with gentle shores» on the glacier surface.

Recent artworks include Earth — Moon — Earth (Moonlight Sonata Reflected from the Surface of the Moon), 2007 which involved the transmission of Beethoven's Moonlight Sonata to the moon and back; Vatnajökull (the sound of), 2007 - 8 — a live phone line to an Icelandic glacier; and All the Dead Stars, 2009; a large map documenting the locations of the 27,000 dead stars known to humanity.

Examination of recent rapid supraglacial (i.e. on the surface) lake drainage documented short term velocity changes due to such events around 10 %, but little significance to the annual flow of the large glaciers outlet glaciers (Das et.al, 2008).

Using 10Be surface exposure ages and radiocarbon - dated lake sediments, we constructed a detailed chronology of ice - margin fluctuations over the past 10 k.y. for Jakobshavn Isbræ, Greenland's largest outlet glacier.

The heavily crevassed surface (extending to the distant horizon) of Jakobshavn Isbrae, one of Greenland's fastest outlet glaciers, is shown on this large iceberg that calved from the glacier's end.

This conclusion has subsequently been supported by an array of evidence that includes both additional large - scale surface temperature reconstructions and pronounced changes in a variety of local proxy indicators, such as melting on icecaps and the retreat of glaciers around the world, which in many cases appear to be unprecedented during at least the last 2000 years.

6 Ice age — time in the past when continental glaciers covered large parts of Earth's surface Global warming — a gradual increase in the temperature of Earth's atmosphere Greenhouse gas — Gases in the atmosphere, such as carbon dioxide, that trap solar energy Ozone hole — a large area of reduced ozone concentration in the stratosphere, found over Antarctica Chlorofluorocarbon — chlorine compounds that are the main cause of ozone depletion KEY TERMS

Projections of future large - scale mass change are based on surface mass balance models that are open to criticism, because they ignore or greatly simplify glacier physics.

Huge sheets of ice (glaciers) cover large parts of the Earth's surface.

The large ice shelves can exist in part due to the lower surface melt rates and the lower flow rates of the glacier.

In principle, a large enough return flow of fresh water from rivers and glaciers could reduce the density of the surface waters sufficiently to stop them from sinking, in which case the whole AMOC would stop.

In 2002, the Larsen B ice shelf collapsed; in 2003, the World Glacial Monitoring Service reported that «The recent increase in the rates of ice loss over reduced glacier surface areas as compared with earlier losses related to larger surface areas (cf. the thorough revision of available data by Dyurgerov, 2002) becomes even more pronounced and leaves no doubt about the accelerating change in climatic conditions.»
