Impact of Supraglacial Lakes on Ice-Shelf Stability
We study ice-shelf response to meltwater load movement in the area of the McMurdo Ice Shelf adjacent to McMurdo Station and the Pegasus Ice Runway. As meltwater accumulated in surface lakes on the floating ice shelf, the ice shelf must flex in accord with hydrostatic equilibrium (floatation). This f...
