Ground-based radar

The ground-based radar system we used is a coherent system; it records a time-domain voltage induced in the receiving antennas, and thus preserves both the phase and the amplitude of the echoes. The transmitted pulse is +/- 2000 volts and the center frequency of the mono-pulse depends on the lengths chosen for the antennas, which … Continue reading

Ice-shelf seismics

During the 2012 season we conducted active and passive seismics on Beardmore Glacier, about 30 km upstream from the grounding line. During this season (2013-2014), we conducted seismic experiments on the Ross Ice Shelf a few km downstream of the Beardmore Glacier.       Paul installs GPS receiver (background) and Max installs a passive … Continue reading

Transantarctic outlet glacier dynamics

Work on Beardmore Glacier, an outlet glacier in the Transantarctic mountains, has been funded by the National Science Foundation Division of Polar Programs. I am part of this research project, led by Twit Conway (UW) and Paul Winberry (Central Washington University). Recent observations of rapid changes in discharge of fast-flowing outlet glaciers and ice streams … Continue reading
