Ross Ice Shelf

travel wonder in Antarctica

Why the
Ross Ice Shelf of
Antarctica if special

An ice shelf is a thick plate of ice that floats on the sea (or rests on a seabed) but is still attached to the glacier that feeds it. The one of the Ross Sea is the world's largest and is as big as France.

tips & insights

In 2000, an iceberg measuring 300 kilometers (180 miles) in length broke away from the Ross Ice Shelf. My red arrow on the satellite image (see photo) points out that elongated calved iceberg that was officially named B-15.

Although B-15 is gigantic, its breakaway reduced the size of the Ross Ice Shelf by only two percent.

If global warning were to completely melt the Ross Ice Shelf and its sister the Ronne Ice Shelf, the oceans around the world would rise up to 70 meters (220 feet). This would inundate coastal cities like Shanghai and New York.

However, the corresponding rise in the air temperature would create enough additional snow over the Antarctica glaciers to replenish the melted ice. Note: Unfortunately, this would not be the case with northern hemisphere glaciers such as those in Greenland.

The frozen ice sheet over the Ross Sea helps preserve the lifespan of the glacier that feeds it, for two reasons. It helps break the glacier's journey to the sea. And, it adds distance between the glacier and the open sea water, which has a warming effect.
