MT site locations across the central TAM and surroundings. Locations and physical features are plotted using a MODIS satellite base map⁷². Grid north is up and both latitude–longitude and Universal Polar Stereographic (UPS) coordinates are overlain on main panel. Orange diamond denotes CTAM multi-investigator camp location active during 2010–11 austral summer season (orange sites), whereas yellow diamond denotes Ross Ice Shelf field camp (RISC) for 2011–12 season (yellow sites). Specific sites discussed in text are labeled. The sole passive seismic station^{22, 23} within the field of view is MILR. Beardmore and Nimrod glaciers are BM and NR, whereas RIS and PPl are Ross Ice Shelf and Polar Plateau, respectively. Within the TAM, the MT transect lies along the lesser Law–Walcott–Lennox–King glaciers. In the inset, WA and West Antarctica, EA is East Antarctica, SP is South Pole, and RI is Ross Island
