Formation of sea ice ponds from ice-shelf runoff, adjacent to the McMurdo Ice Shelf, Antarctica by Macdonald, Grant J., Popović, Predrag, Mayer, David P.

“…Ponds that form on sea ice can cause it to thin or break-up, which can promote calving from an adjacent ice shelf. Studies of sea ice ponds have predominantly…”

Simple Rules Govern the Patterns of Arctic Sea Ice Melt Ponds by Popović, Predrag, Cael, B B, Silber, Mary, Abbot, Dorian S

“…Climate change, amplified in the far north, has led to rapid sea ice decline in recent years. In the summer, melt ponds form on the surface of Arctic sea ice,…”
