Abstract

This thesis presents the design of the hard- and software of a new shape measurement probe for ice boreholes. It allows logging the borehole’s shape and its evolution in time, which relates to the local deformation regime in the borehole’s vicinity. Therefore, the enhanced geometrical data contribute to the understanding of ice-sheet dynamics especially as a reference when verifying numerical simulations. The presented probe is designed to measure 16 individual points over the borehole circumference with three axial acceleration sensors based on micro-electro-mechanical systems (MEMS) design and the borehole inclination. This geometry data combined with the additional parameters pressure, density and temperature should be logged in boreholes filled with drill fluids over a maximum depth of 3.5km in Greenland and Antarctica.
