Synopsis of glacier researches in Patagonia, 1993

The Glacier Research Project in Patagonia with a theme of Characteristics of Recent Glacier Variations in Patagonia, Southern Andes was carried out in the field during the austral summer of 1993/94 : from 9 November to 28 December 1993 at and around Upsala, Ameghino, Moreno and Tyndall glaciers, outlet glaciers from the Southern Patagonia Icefield, and around the Northern Patagonia Icefield. The research topics accomplished include : 1) ice-thickness changes between 1990 and 1993, 2) flow of glaciers, 3) meteorological conditions and heat balance, 4) morphology and thickness of glaciers, 5) landforms around glaciers and Holocene glacier variations, and 6) aerial photographic survey (Northern Patagonia Icefield). As ancillary projects, the following topics were also studied : 7) lake- and glacier-sediments, dendrochronology and glacier fluctuations, 8) recent climatic changes in the Patagonia region. Outline of the project and summaries of the results are presented.
