Abstract
Summary In a recent paper, Evison, Ingham, Orr & Le Fort concluded from the analysis of dispersed Love and Rayleigh waves along four complex wave paths that the thickness of the crust under Marie Byrd Land is around 25 km. However, gravity and surface elevation evidence suggest a thickness of about 30 km. It is believed that the agreement between these methods can be improved by a more realistic choice of crustal wave velocities than those used by Evison & others.
