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

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
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
Beardmore Glacier, Antarctica… nearly there (again)
Our team is ready and waiting in McMurdo for our second field season on the Beardmore Glacier. Last year we were about 30 km from the grounding line of this massive glacier moving East Antarctic ice through the Transantarctic Mountains and into the Ross Ice Shelf. This year we will be positioned near the grounding … Continue reading
McMurdo Station and surroundings
We have been and are still waiting in McMurdo Station for our flight to Beardmore Glacier. While waiting, I have a chance to put together some blog posts! The station has some highlights: interesting walks, interesting people, and interesting history. We went to visit Captain Robert Falcon Scott’s Discovery hut near the station. Built in … Continue reading
