Research Abstract

(1) At Perito Moreno Glacier of the Southern Patagonia Icefield, we measured the glacier surface heights, glacier flow velocity, and calving speed, and long-term temperature at the upper reach.We drilled 510m boreholes with a hotwater drill.Three LIA advances in 15C, 17C and 19C were recognized. (2) The fan deltas distributed on the eastern side of the Northern Patagonia Icefield were investigated. Variations of 21 outlet glaciers of the NPI between 2004/5 and 2008/9 resulted in a total area loss of 5.8 km^2. (3) With the JAMSTEC's research ship [Mirai] we cored sea floor sediments at the offshore of the NPI.
