Glaciological investigations in the grounding line area of the Foundation Ice Stream, Antarctica
During the summer of 1994-95, an extensive program of glaciological, geophysical and geodetic measurements was carried out along a flow line of the Foundation Ice Stream. The collected data are the basis for mass flux determinations in the entrainment area of the ice stream into the RonneIce Shelf....
