| Outline of Final Research Achievements |
We carried out satellite and field measurements to study the role of glacier dynamics in rapid retreat of calving glaciers. Glacier front positions and ice speed over the entire area of Southern Patagonia Icefield were quantified from 1984 to 2011. Details of the data revealed the fundamental role of glacier dynamics in the significantly large retreat observed in several glaciers. Lake measurements confirmed the influence of bed geometry on glacier stability, and unique lake temperature structures in front of calving glaciers. We also performed hot water drilling on glaciers on Livingston Island in Antarctic Peninsula. Subglacial and englacial measurements provided us clues to understand the mechanism of short-term ice speed variations. These results demonstrated that the glacier dynamics is a key driver of the recent rapid retreat of calving glaciers, and also suggested potentially important role of ice-lake interactions in the glacier change.
