But scientists increasingly attribute much of the observed grounding line retreat — particularly in West Antarctica — to the influence
of warmer ocean water seeping beneath the ice shelves and lapping against the bases of glaciers, melting the ice from the bottom up.
These changes include melting and thinning of the coastal margins (30) and surging of outlet glaciers (29, 31), which may be contributed to by the intrusion
of warming ocean waters (32).

of warmer ocean water and increasing amounts of meltwater from the surface of the Greenland ice sheet.
When cold surface water no longer sinks into the depths, a deeper layer
of warm ocean water can travel across the continental shelf and reach the bases of glaciers, retaining its heat as the cold waters remain above.
Rise is due to both melting ice and the thermal expansion
of warming ocean waters.
R Gates > Apparently the many scientists who have been studying the largest and perhaps most important «pocket»
