Characteristic Seismic Waves Associated with Cryosphere Dynamics in Eastern Dronning Maud Land, East Antarctica

Distribution of subglacial lakes (blue solid circles) in wide region of Wilkes Land, East Antarctica. The target areas for several geophysical surveys including the International Polar Year (IPY 2007–2008) campaign period are demonstrated, by yellow lines (air-borne geophysics by AGAP), red line (Chinese traverse by AGAP), green triangles (seismic stations by AGAP) and several black circulated areas (the other air-borne geophysics projects). (The map is by courtesy of Professors R. Bell and M. Studinger; http://www.ldeo.columbia.edu/~mstuding/AGAP/). The formation, distribution and stability of subglacial lakes tell us the fundamental question how the tectonic processes control them.
