30 years ago, Walter Alvarez (1982) suggested the Scotia Sea as an outlet for flow within the asthenosphere from the shrinking Pacific into the growing Atlantic. He conceived such flow necessary to establish mass balance between the two mantle domains, and argued that the Scotia Sea is one of the few potential outlets of the Pacific, where neither continental roots nor subducting slabs interfere with the proposed shallow mantle flow. We test this hypothesis by calculating the present-day dynamic topography (DT) of the Scotia Sea in search for a systematic trend in DT from west to east in response to a flow related pressure gradient in the sublithospheric mantle.
