Retreat of glaciers since Current Affairs, GK & News
The researchers from Australian Antarctic Program have discovered a network of lakes lying under the ice during their 160-day expedition to the Totten Glacier, the largest in eastern Antarctica. The lakes were detected by scientists setting off small explosives 2m below the surface of the Totten glacier and listening to the reflected sound. They are ..
The Greenland glacier was one of the fastest shrinking ice and snow masses on the earth. A NASA study proves that it is growing again. The Jakobshavn glacier was retreating at 3 km annuallu. In the past two years it has now started to grow at the same pace. However scientists beleive that this is ..
Totten Glacier is a large glacier draining a major portion of the East Antarctic Ice Sheet, through the Budd Coast of Wilkes Land in the Australian Antarctic Territory. The catchment drained by the glacier is estimated at 538,000 km2 extending approximately 1100 km into the interior and holds the potential to raise sea level by at least 3.5 m. As per recent reports Totten Glacier might just ..
Glacier Mass Balance is the gain and loss of ice from the glacier system. When glaciers lose more mass than they receive, it will be in negative mass balance and so will recede. When glaciers gain more mass than they lose, they will be in positive mass balance and will advance. Whereas, when Glaciers gain ..
