[ACC38-P01] Estimation of glacier velocities at Pio XI in the Southern Patagonia Icefield detected by ALOS-2/PALSAR-2
In order to understand the dynamics of Pio XI glacier, this paper reports the temporal variations of flow velocities and terminus positions by using Advanced Land Observation Satellite-2/Phased Array-type L-band Synthetic Aperture Radar-2(ALOS-2/PALSAR-2)data acquired in 2015.
In 2015, Pio XI flows < 4m/d from Febrary to June. However in the term from August to September, Pio XI revealed significant acceleration. In 2015, the primary flow of Pio XI is terminate into Greve lake from north tongue.
