Outline of Final Research Achievements

We carried out field observations on the Glaciar Perito Moreno, Patagonia in the South America. From those results, annual variations in location of the glacier terminus, distribution of the terminal flow speed, and ice thickness of the glacier ablation area, are revealed. We, however, have not yet accomplished to investigate hydraulic correlations between the glacier terminal / ice thickness variations and water pressure of the proglacial lake evaluated from the lake depth data, unfortunately. Nevertheless, we have stored precious data set for the glacier, those have been seldom obtained on other calving glaciers. We are convinced that our data set should contribute to clarify mechanism of calving glaciers’ variations through continuing the analysis.
