Effects of impurities on the ice microstructure of Monte Perdido Glacier, Central Pyrenees, NE Spain
Monte Perdido Glacier, located in the central Pyrenees, is one of the southernmost glaciers in Europe. Due to climate change, this glacier is suffering an accelerated mass loss, especially in the last decades. If the current trends persist, this glacier is expected to disappear in the next 50 years....

Monte Perdido Glacier, located in the central Pyrenees, is one of the southernmost glaciers in Europe.
