Antarctica plays a central role in global tectonic evolution. Competing theories have been put forward to explain the formation of the Transantarctic Mountains (TAMs) and the Wilkes Subglacial Basin (WSB), primarily due to a lack of information on the crustal thickness and seismic velocity of these areas. The research team is attempting to resolve how the TAMs and WSB originated and how their formation relates to Antarctica's geologic history. Since most of Antarctica is covered by large ice sheets, direct geologic observations cannot be made; therefore, "remote sensing" methods like seismology must be used to determine details about the earth structure.
