Straddling the southern Andes Mountains in Chile and Argentina, these glaciers have thinned significantly in the past four decades.
Throughout Antarctica, broad ribbons of ice known as ice streams shed large quantities of ice into the ocean.

This image shows the latest estimate of the ice edge around Law Promontory, which juts out from East Antarctica’s coastline near Stefansson Bay.
To the untrained eye, Antarctica may look like a giant piece of solid ice that rarely changes, but scientists studying the continent have long known better. The icy surface is dynamic, with glaciers and "streams" of ice flowing toward the ocean.
When this closely watched slab of floating ice births a giant iceberg, it will not be the first time it has seen dramatic change.
