Geophysical studies were undertaken during two Ocean Drilling Program cruises in and around the Southern Ocean. Log data were collected during Legs 181 and 188, and rock-magnetic data were collected from samples taken during Leg 181. A combination of downhole logging and continuous-core geophysical measurements was used to create synthetic seismograms to ground-truth seismic profiles recorded in Prydz Bay, Antarctica, and to derive high-resolution mass accumulation rate (MAR) curves of Neogene deposition around the margins of the Southern Ocean. The results of this study were used to document changes in the intensity of the Deep Western Boundary Current east of New Zealand, expansion of the East Antarctic ice sheet and acceleration of the tectonic uplift of the Southern Alps.
