Now seafloor sediments reveal that Larsen B's grounding line had remained stable for thousands of years before the ice shelf's collapse.
If they begin to melt, however — particularly as they're exposed to warmer ocean water — the shelves become thinner and the grounding line begins to retreat backward, causing the glacier to become less stable and making the ice shelf more likely to break.
The MISI is based on a number of studies that indicated the theoretical existence of the instability... The most fundamental derivation, that is, starting from a first - principle ice equation, states that in one - dimensional ice flow the grounding line between grounded ice sheet and floating ice shelf can not be stable on a landward sloping bed.
