CRITERIA FOR MEASUREMENT OF STRAIN RATES IN DEEP BORE HOLES IN POLAR GLACIERS
The different components of vertical strain rate are discussed, as well as their relation to horizontal strain rate. Based on a simplified model, strain rates as a function of depth below the surface are calculated for Camp Century, Greenland, and Byrd Station, Antarctica. The results indicate that...

Summary: | The different components of vertical strain rate are discussed, as well as their relation to horizontal strain rate. Based on a simplified model, strain rates as a function of depth below the surface are calculated for Camp Century, Greenland, and Byrd Station, Antarctica. The results indicate that only very high measurement accuracy is likely to yield useful results. Measurement of horizontal shear rate is also discussed. (Author) |
