Seismic sounding by early Soviet expeditions identified two subglacial mountains in Antarctica: the Gamburtsev Mountains (discovered in 1957–59 and named for the Soviet geophysicist G. A. Gamburtsev) and the Vernadskiy Mountains (named in 1963–64 for the geochemist V. I. Vernadskiy). An attempt is made here to correlate the subsequent air‐borne radar surveys in Enderby Land and around the South Pole and to determine the bedrock topography along the 40–42°E meridian by computing the values of gravity anomalies. A previous supposition that there is no connection between the two subglacial mountain forms is confirmed; they are found to be separated by lower‐lying relief.
