The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies. The glacier currently loses depth at a rate of about 5 metres (16 ft) per year [ 2 ] and has receded more than 1.5 km (0.93 mi) and lost over half of its volume in the past 125 years.
One of the more accessible in the Canadian Rockies is the Athabasca Glacier, which is an outlet glacier of the 325 km 2 (125 sq mi) Columbia Icefield. The Athabasca Glacier has retreated 1,500 m (4,900 ft) since the late 19th century. Its rate of retreat has increased since 1980, following a period of slow retreat from 1950 to 1980.
The Columbia Icefield is the largest ice field in North America's Rocky Mountains. [1] Located within the Canadian Rocky Mountains astride the Continental Divide along the border of British Columbia and Alberta, Canada, the ice field lies partly in the northwestern tip of Banff National Park and partly in the southern end of Jasper National Park.
A newly published study led and authored by the director of the World Glacier Monitoring Service reports that glacier melting is now occurring at an unprecedented accelerated rate. The examination ...
Scientists have looked back in time to reconstruct the past life of Antarctica’s “Doomsday Glacier.” Their findings give an alarming insight into future melting The ‘Doomsday Glacier’ is ...
The glacier has since had a negative mass balance trend. [20] The Juneau Icefield Research Program also has studied the mass balance of the Lemon Creek Glacier since 1953. The glacier has had an average annual balance of −0.44 m per year from 1953 to 2006, resulting in a mean loss of over 27 m of ice thickness.
Sea level rise is accelerating, the melting of Europe’s Alpine glaciers shattered records and devastating floods, drought and heatwaves hit in 2022, the World Meteorological Organisation (WMO) said.
The ablation zone is found at the lowest altitude of the glacier, where ablation of material is lesser than accumulation. Ablation zone or ablation area refers to the low-altitude area of a glacier or ice sheet below firn with a net loss in ice mass due to melting, sublimation, evaporation, ice calving, aeolian processes like blowing snow, avalanche, and any other ablation.
