Ice Thickness and Surface Elevation, Southeastern Ross Embayment, West Antarctica (D.D. Blankenship et al.)

Subglacial Topography

Figure. Subglacial topography obtained by subtracting ice thickness from CASERTZ airborne radar sounding from surface elevations. The assumed crustal boundary for the Ellsworth/Whitmore crustal block (EWB; -250 m a.s.l.) is shown by the broken red line; the boundary for the Whitmore Mountains/Ross Embayment transitional crust (WRT; -500 m a.s.l.) is indicated by the broken orange line.
