Geological summary
Magnetic and seismic data suggest that a submarine caldera with a central lava dome is present east of Granite Harbor and north of Ross Island, near the western coast of the Ross Sea and near the southern end of the submarine Victoria Land Basin. Apparent temperatures above the Curie temperature suggested the presence of magma and a Holocene age (Behrendt et al., 1987).
