Radar sounding of englacial water on Storglaciaren, Sweden
Listed in NASA Earthdata CMR
These data were acquired by a ground-based, ice-penetrating radar study of Storglaciaren in July of 2001 and 2002.
Description
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.
