| In
the Bhutan Himalayas, ASTER data have revealed significant spatial variability
in glacier flow, such that the glacier velocities in the terminus zones
on the south side exhibit significantly lower velocities (10 - 20 m/yr),
versus much higher flow velocities on the north side (20 - 200 m/yr). The
velocity magnitude for the northern glaciers suggests a relatively high
basal velocity versus substantially stagnated ice for the southern glaciers.
These and other results are emerging from the Global Ice Measurements from
Space (GLIMS) project, under the direction of Dr. Jeff Kargel of the University
of Arizona. This ASTER scene was acquired 20 November 2001, is centered
near 28.3 degrees north latitude, 90.1 degrees east longitude, and covers
an area of 32.3 x 46.7 km. |
