GEOMORPHOLOGICAL MAP OF THE COASTAL AREA OF THE STRAITS OF MAGELLAN BETWEEN PUNTA DUNGENESS AND BAHÍA INÚTIL (CHILE)
This paper presents the first results of the geomorphological survey of the coastal area Strait of Magellan between Punta Dungeness and Cabo San Isidro (Pategonia) and between Punta Catalina and Punta Yanou (Tierra del Fuego). The data on the map are mainly referred to the mapping and on land survey...

This paper presents the first results of the geomorphological survey of the coastal area Strait of Magellan between Punta Dungeness and Cabo San Isidro (Pategonia) and between Punta Catalina and Punta Yanou (Tierra del Fuego). The data on the map are mainly referred to the mapping and on land survey made during the 1991 /92 Italian Expedition within the National Antarctic Research Project. During this expedition regional-scale investigations were carried out that allowed an improvement of the features links to climatic variations of the Upper Quaternary. The studies have so far been focused on the littoral dynamics (morphological surveys of intertidal beach and beach samples). These studies allowed a preliminary reconstruction of sediment dispersion pattern from North-East to South-West , along the central axis of the Strait and in the opposite direction, in the subcoastal areas of particular physiographic units (Primera and Segunda Angostura).
