This paper provides an overview of Russian geophysical studies of Mac. Robertson, Princess Elizabeth and Wilhelm II Lands, East Antarctica. The dedicated complex geological and geophysical investigations during the 17–19th SAE (1971–1974) austral summer field seasons paved the way for systematic research works. These included deep seismic sounding, ground-based gravity measurements with reflection seismic sounding over the 30 x 30 km survey grid, and combined aeromagnetic surveys on a scale of 1:2 000 000, and radio-echo sounding (RES). After a significant gap, a new phase of the investigations in this region has been underway since the 31st SAE (1985/86) field season. The airborne geophysical investigations include airborne magnetic and RES surveys along the traverse lines with the 5 km interval between the profiles, which have covered the area between 62° E and 88° E in East Antarctic, from the coastal line to the 2800 m ice surface elevations in the South.
