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

Put in: soon

I was optimistic for a timely put-in to our field work, but not unexpectedly we are waiting a few days for weather, planes, and destiny to cooperate. This gives time to reminisce about last year’s put in. First we will go to a location called “Central Transantarctic Mountains”, or CTAM. This was a base of … Continue reading
