Dye 2 Position and Topography 1986.

Purpose: (1) To provide a satellite based fixed point close to Dye 2 for position and elevation reference. By measurement of this point, the surface velocity can be calculated; (2) To measure the surface topography within 3 km from the station. Irregular ice flow should be accompanied by changes in...

Description
Summary:Purpose: (1) To provide a satellite based fixed point close to Dye 2 for position and elevation reference. By measurement of this point, the surface velocity can be calculated; (2) To measure the surface topography within 3 km from the station. Irregular ice flow should be accompanied by changes in surface slope, thus the surface topography can be used as an indicator for variations in surface strain. The main objective was to obtain a precise fix, i.e., latitude, longitude and elevation at station Dye-2 on the Greenland ice cap. The site expedition established a benchmark 100 meters from Dye-2 and set up a Geoceiver with throdolite transportation to the site. Topographical data for the Geoceiver site is provided in this report.
