Abstract
Abstract Two geomorphological types of ice shelves are distinguished: (a) land‐ice shelves freezing and melting at the base, and including most of the Antarctic ice shelves, for example, Ross Ice Shelf; (b) fast ice with active freezing at the base, for example, McMurdo Ice Shelf. The mechanism of exaration of the sea floor by the two types of ice shelves is examined, together with erosion rates and the nature of the exaration relief. A classification of unconsolidated deposits formed by ice shelves is offered.
