From the abstract of the referenced paper:
During the Australian National Antarctic Research Expeditions (ANARE) Voyage 6, 1987, observations were made of heavily glaciated Heard Island. Features of moraines and their sediments were recorded at three glaciers at the north-western part of the island. They indicated that in these glaciers basal movements has little corrosive effect. Erosion with up-transport of debris occurs mainly at the transition from steeper to lower gradients. Moraines formed there may contain basal till. In other positions moraines are formed mainly of supraglacial debris from rockfalls or wind transport. The moraine sediments are mainly waterlaid or debris flows and, in places, possibly flow till.
