Mass Balance and Velocity Data for Greenland Ice Sheet at High Elevations

By Beata Maria Csatho1, Ashlynn Narkevic1, and Ivan Parmuzin1
1. University at Buffalo SUNY UB

This is an estimation of mass balance of the Greenland Ice Sheet at higher elevations, computed as the difference between the estimated annual total snow accumulation and ice discharge. Measurements are taken at 161 stations located 30 km apart, at 2000 m elevation that circumnavigates Greenland. Ice velocities are determined from GPS data, and ice thickness from ice-penetrating radar. Results are presented for single gates between adjacent stations, and gate combinations representing larger areas.

Abstract

This is an estimation of mass balance of the Greenland Ice Sheet at higher elevations, computed as the difference between the estimated annual total snow accumulation and ice discharge. Measurements are taken at 161 stations located 30 km apart, at 2000 m elevation that circumnavigates Greenland. Ice velocities are determined from GPS data, and ice thickness from ice-penetrating radar. Results are presented for single gates between adjacent stations, and gate combinations representing larger areas.
