   "abstract": "A 1995\u201396 aeromagnetic survey over part of the Sinuous Ridge (SR) beneath the West Antarctic Ice Sheet (WAIS) divide shows a 70-km diameter circular pattern of 400\u20131200-nT anomalies suggesting one of the largest volcanic caldera(?) complexes on earth. Radar-ice-sounding (RIS) shows the northern part of this pattern overlies the SR, and extends south over the Bentley Subglacial Trench (BST). Modeled sources of all but one the caldera(?) anomalies are at the base of <1\u20132-km thick ice and their volcanic edifices have been glacially removed. The exception is a 700-m high, 15-km wide \"volcano\" producing an 800-nT anomaly over the BST. \u201cIntrusion\u201d of this \u201cvolcano\u201d beneath 3 km of ice probably resulted in pillow basalt rather than easily removed hyaloclastite erupted beneath thinner ice. The background area (\u2212300 to \u2212500-nT) surrounding the caldera(?) is possibly caused by a shallow Curie isotherm. We suggest uplift of the SR forced the advance of the WAIS.",
