Research
I am interested in many aspects of glaciology. In particular, I
am intrigued by all aspects of ice dyanimcs: from ice flow
at a divide on an icesheet to rapid sliding events on mountain
glaciers. I have thus far focused on two primary topics:
Snow and Firn Grain Size: I am helping develop a device to measure snow
grain size in cores and in boreholes. The
device records how the light intensity falls off with distance when a
point source is emitted into the snow pack. To find
out more check out this poster: Grain Size Poster
Subglacial Dynamics of a Mountain Glacier: I did extensive research on
Bench Glacier in Alaska. My area of research
was how water flowed at the bed of the glacier. I am also
currently working on an rapid motion and water pressure
event that occurred in autumn. Interesting features of this event
are:
1) a varying relationship between water pressure and sliding speed even
in the span of 7 days
2) a sharp water pressure drop when sliding begins
3) two phases of reverse motion of at least 5 cm
Sorry for the lack of pictures - they are coming soon!
