Geophysical data acquired using R/V Polarstern constrain the structure and age of the rifted oceanic margin of West Antarctica. West of the Antipodes Fault, the 145 km wide continent-ocean transition zone (COTZ) of the Marie Byrd Land sector resembles a typical Atlantic-type margin. New gravity and...
