Radar sounding of englacial water on Storglaciaren, Sweden

These data were acquired by a ground-based, ice-penetrating radar study of
Storglaciaren in July of 2001 and 2002. Closely spaced grids were made in 4
locations using GPR at frequencies of 50 and 100 MHz. GPS measurements of the
grid locations were acquired but individual radar traces are not geolocated.

The purpose of this project is to understand how water is delivered from the
surface of a glacier through a linked system of cavities and conduits to the
bed, and the evolution of this system through time. Our research site is
Storglaciaren, a polythermal glacier in Arctic Sweden. The methods we utilize
are ice penetrating radar to image englacial features containing water and
hot-water drilling to intersect them. A variety of down-hole instruments
including bore-hole video are deployed to study the morphology of water-filled
conduits. The latter activities are carried out by our co- investigators at
Portland State University and the University of Stockholm. The radar portion
of the project has been carried out by St. Olaf College and is the focus of
this listing.
