Abstract

This paper studies the ice patch development of the Jou Negro ice patch since the Little Ice Age, its structure and current dynamics. The ice patch lost mass throughout the 20th century following the general air temperature rise in the region. It was originally a glacier, but from the beginning of the 20th century it became a glacial ice patch, showing considerable loss of mass after the 1980s. The internal structure with 2 basal layers of saturated and partially frozen sediments upon which the glacial ice lies, favours contemporary movement. A considerable mass loss in 2009 has been detected associated with small displacements by sliding. The considerable clast cover and topoclimate favours the maintenance of the ice patch, which is in a state of imbalance with current environmental conditions
