The outcrop to the north is rich with minerals that interact with rainwater to produce an acidic environment on rock surfaces that leads to rapid chemical weathering of rock, while the combination of minerals in the outcrop to the south produces a less acidic environment that slows weathering. Nowadays (2014), Gorner Glacier retreats about 30 metres (98 ft) every year, but with a record loss of 290 metres (950 ft) in 2008. The Gorner Glacier is the source of the Gornera river which flows into Zermatt, although most of the water is diverted into the Grande Dixence hydroelectric system and is pumped into Lac des Dix. The rockfalls send debris ranging from pebbles to large boulders tumbling down onto the ice in a rush. Land. Likewise, a moving glacier can carry with it evidence of geologic events it has witnessed. Snow and Ice. All … (pdf). They also stated that New Zealand glaciers on the whole had lost 5.8 cubic kilometers (roughly 1.4 cubic miles) over the same time period. Debris bands with different geochemical compositions are visible. NIWA scientists stated that this glacier had retreated by 5 kilometers (about 3 miles) over the previous three decades. Like almost all other glaciers in the Alps, and most glaciers on the globe as well, due to global warming the Gorner Glacier is a retreating glacier—and in quite a dramatic way.

It is part of a glacier system in- ... out of equilibrium with a clear trend toward glacial retreat. The Great Aletsch is part of a UNESCO World Heritage Site. Glaciologists analyse the activity of glaciers year on year. The bottom image shows Gorner Glacier, another valley glacier near Zermatt. Caption by Adam Voiland. Four smaller glaciers converge to form the Aletsch Glacier at Concordia Place. When glaciers began their final retreat 10,000 years ago, they left … But it’s not long before the snowy surfaces are painted over with coats of dust, soot, ash, pollen, salt, sand, rocks, and other debris. Where mighty glaciers once Glaciers may retreat when their ice melts or ablates more quickly than snowfall can accumulate and form new glacial ice. The method is shown to give results consistent with ground-based observations for the Franz Josef and Gorner glaciers and is further applied to estimate the retreat of Viedma, a glacier with no available ground measurements. Winds can blow in plumes of smoke and dust to coat surfaces with black, gray, metallic, even reddish or yellow tones. What's hot in the news around climate and sea ice and what are scientists talking about now? NASA Goddard Space A trip up to the Gornergrat takes about 35 minutes and once you are up there you get a magnificent, 360° panoramic view in the midst of the Alps; the Matterhorn, Liskamm and the Monte-Rosa group with a view over the glacier.
