CALCULATING BOREHOLE GEOMETRY FROM STANDARD MEASUREMENTS OF BOREHOLE INCLINOMETRY.

The most common method for estimating borehole geometry in glaciers is standard borehole inclinometry. Inclinometry data collected during the drilling operation are used to monitor the progress of drill (Gundestrup et al. 1982) and eventually are used to orient and interpret the stratigraphy in the core. Subsequent remeasurements of borehole geometry are the most accurate methods for estimating intraglacial strain rates. In this paper the authors describe the details of a method they used in analyzing inclinometry data collected in the borehole at DYE-3, Greenland. Refs.
