We arrived to CTAM by LC-130 on December 9, 2013 after a few days on hold in McMurdo. The put-in to action came as a surprised as we started the day listed in red on the flight board, but we came ready quick when it went green. We had to wait three nights at CTAM … Continue reading

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
