Gravity anomaly map.
EGM2008 gravity anomaly map. The hypothesis was detailed in a paper by Weihaupt in 1976. Evidence cited included a large negative gravity anomaly coincident with a subglacial topographic depression 243 kilometres (151 mi) across and having a minimum depth of 848 metres (2,782 ft). The claims were challenged by Charles R. Bentley in 1979.

As explained above, Bouguer gravity removes from the free-air gravity the signal expected purely from surface relief, assuming a (constant) crustal density. Over the whole spectrum, the Bouguer map is dominated by the crustal thickness dichotomy between nearside and farside, and the South Pole-Aitken basin is also prominent.This part of the DVP is bounded in the north by the Kachchh rift zone and limited to the east by the Cambay rift zone. Accordingly, the gravity map shows a distinct anomaly pattern in this domain. The area is mostly populated with high-frequency gravity highs in the borders and separated with gravity low in the central part of the area.
