            6 =========================
            7 
            8 PISM is often used to model whole ice sheets surrounded by ocean, with attached floating
            9 ice shelves, or smaller regions like outlet glaciers flowing into embayments and possibly
           10 generating floating tongues. This section explains the geometry and stress balance
           11 mechanisms in PISM that apply to floating ice, at the vertical calving faces of floating
           12 ice, or at marine grounding lines. The physics at calving fronts is very different from
           13 elsewhere on an ice sheet, because the flow is nothing like the lubrication flow addressed
           14 by the SIA, and nor is the physics like the sliding flow in the interior of an ice domain.
           15 The needed physics at the calving front can be thought of as boundary condition
           16 modifications to the mass continuity equation and to the SSA stress balance equation. The
           17 physics of grounding lines are substantially handled by recovering sub-grid information
           18 through interpolation.
