The Antarctic plateau provides a unique window to observe the dynamic processes that lead to the transfer of mass, energy, and momentum from the solar wind into and throughout the geospace system. Over the course of one day, geomagnetic field lines emanating from the southern high latitude region extend to the outer dayside magnetosphere, boundary layers and cusp across the polar cap to the mantle, lobe and portions of the plasma sheet.
