abstract = "{Drake Passage is considered a gateway for oceanic and asthenospheric
flows since its opening, entailing widespread consequences for
climate and plate tectonics, respectively. Both the surface and
the 50 km upward continued Bouguer anomaly maps of the Scotia
Sea and surrounding areas, based on Gravity Recovery and Climate
Experiment gravity satellite data, improve our knowledge of deep
lithospheric structures and the asthenosphere. We show that the
West Scotia Sea is likely to be underlain by an anomalously low-
density upper mantle. Gravity data are compatible with variable
lithospheric thicknesses related to asthenospheric currents. The
new data suggest that the development of the Shackleton Fracture
Zone since the middle Miocene was probably a main factor that
determined the evolution of the eastward Pacific mantle flows
and the extinction of the West Scotia Sea oceanic spreading
around 6 Ma ago. Deep lithospheric roots are likely to divert
asthenospheric currents around them, flowing eastward through
Drake Passage.}",
