Surface-wave dispersion in Byrd Land, Antarctica

UNIVERSITY OF WISCONSIN DEPARTMENT OF GEOLOGY AND GEOPHYSICS GEOPHYSICAL AND POLAR RESEARCH CENTER, MIDDLETON, WISCONSIN 53562

Abstract

Assuming constant density and Poisson's ratio of 0.25, theoretical surface-wave dispersion has been computed for the Byrd Land area in Antarctica, where the velocity increases monotonically with depth. Comparison with observed dispersion indicates 8 to 10 per cent anisotropy in the ice cap. Such anisotropy was also detected from ultrasonic velocity measurements on snow cores.
