| Outline of Final Research Achievements |
The total glacier recession of the HPN during the study period of 2010-2014 (4 years) is 8.43km2. The largest recession is found at Gl. San Quintin that lost an area of 3.35km2. Other fast retreating glaciers include Gl. Colonia (1.5 km2), Gl. Fiero (0.76 km2), HPN3 (0.71 km2), Benito (0.67 km2), and Gl. Steffen (0.65 km2). On the other hand, I found several glaciers that did no vary substantially during the study period. These are Gl. San Rafael, Gl. Gualas, and Gl. Reicher on the west of the icefield, Gl. Piscis, Gl. Pared Sur, Gl. Arco and Gl. Leon on the east side, and Gl. Exploradores on the north side.
When we look at the recession rate closely, the average recession speed per glacier for 2013-15 is 1/5 of that for 2011-12 and 1/3 of that for 2012-13, indicating that the recession speed has decreased during the study period.
