Inner Core Experiments: Teleseismic exploration of the antipode

A seismic experiment at the antipode of a nuclear test will yield high resolution data for the inner core, outer core, and core‐mantle boundary of the earth that are not obtainable at any other place on the earth's surface. The antipode to the Nevada test site lies 180° opposite in the Crozet basin of the Southwest Indian Ocean between Madagascar and the Kerguelen Islands. An ocean bottom seismometer (OBS) array deployment at the antipode is feasible with present‐day navigation and technology. Current seismic wave propagation techniques can handle the analysis and modeling of data from an antipode experiment. The primary impediments of an antipode experiment are threefold: security of nuclear tests, ship scheduling, funding coordination . Although difficulties are presented by each, they can be overcome.
