Ground penetrating radar data was collected along transects across the ice patches at 250 MHz and 500 MHz frequencies. Traces were collected roughly every 5 cm along the transects with the GPS location and elevation being recorded at each trace location. The data is in a Pulse EKKO format and indicates the thickness of the ice and internal layering. The transects were laid out in a grid manner such that the three dimensional geometry of the patch could be determined. : Purpose: Ground penetrating radar data was collected to image the geometry and internal structure of permanent high alpine ice patches. This data will assist in modelling the formation processes of ice patches, and determining their current accumulation/melt rates. : Summary: This dataset consists of ground penetrating radar data for three high alpine ice patches in the Mackenzie Mountains. This data was collected to determine the internal strucutre of permanent ice patch features, and to provide a better estimate of the rate at which ice patches are melting. This study is a component of the IPY-Federal funded NWT Ice Patch Study.
