Warm ocean currents cause the loss of ice in the Antarctic
Washington: warm ocean currents that are attacking from the bottom layers of ice may help to explain the loss of ice in Antarctica recently, a new study.
A team of scientists use measurements of snow and NASA, cloud, high satellite of the Earth (ICESat) and models to differentiate between the causes are known from the shelves melting ice: ocean currents warm melt part of the most vulnerable of extensions floating ice sheets and melting them with warm air from above. Discovery takes scientists a step closer to providing reliable forecasts of future sea level rise. The researchers concluded that 20 of 54 ice shelves are melting by warm ocean currents.
Most of them in West Antarctica, where glaciers are continental flowing in the direction of the coast, and feed on these platforms accelerated thin ice, and ice exchange over the sea and contribute to sea level rise, according to a statement issued by the British Antarctic Survey.
This ocean-driven thinning is responsible for the loss of ice faster and wider in West Antarctica, and for most of the ice loss in Antarctica during the study period.
"We may lose a large amount of sea ice in summer, warm enough without having to make snow in the upper part of the melting of glaciers," said Hamish Pritchard of the British Antarctic Survey in Cambridge, United Kingdom, who led the study. "You can not do all the work of the ocean without
