Abstract
The Patagonia Icefield (Hielos Patagónicos) comprises Hielo Patagónico Norte (HPN) and Hielo Patagónico Sur (HPS) and is the largest temperate ice body in the Southern Hemisphere with the combined area of 17,200 km2. Glaciological research project in Patagonia was carried out in 1998 and 1999, with the two main objectives; (1) to elucidate the Holocene glacier variations of HPN, and (2) to drill in the accumulation area of Glaciar Tyndall of HPS. The other research topics included; (1) glaciological, meteorological and hydrological resurveys at Glaciar Soler of HPN, (2) study of snow/ice biology (insects and algae) at Glaciar Tyndall of HPS, (3) ice calving observation and measurements of Glaciar Perito Moreno of HPS, (4) bathymetric survey of Brazo Upsala of Lago Argentino in HPS, and (5) aerial survey of Glaciar Soler and HPN outlet glaciers. The background of the project is presented, and field work and some of the major results are described.
