| Research Abstract |
Valuable observational data were obtained in order to verify a hypothesis that a positive feedback can operate between variation of glacier thickness and calving rate into a proglacial lake in case of a lake-calving glacier. In concrete terms, glacier thinning rate, terminal flow speed, water level of proglacial lake and so on were repeatedly measured at Glaciar Perito Moreno in the Patagonia Icefield, South America. In addition, glacier thinning was surveyed on two glaciers and size change was detected through repeat photos on 18 glaciers and glacial lakes, in the Bhutan Himalayas.
