Patagonian Ice Sheet Ice Sheet resulted in a dramatic release of freshwater to the adjacent ocean, decreasing its salinity and altering its circulation, resulting in significant ecological changes both locally and remotely. Patagonian Ice Sheet The Patagonian Ice Sheet was a large elongated and narrow ice sheet centered in the southern Andes that existed during the Llanquihue glaciation. The ice sheet covered all of Chile south of Puerto Montt plus the western fringes of Argentine Patagonia.
