Ice shelf
Appearance
An ice shelf is ice has flowed off an ice sheet and floats on the sea, typically in Antarctica or Greenland. Minor ice shelves may also form due to the accumulation of sea ice. When a chunk breaks off from an ice shelf, this is called "calving", and the product is an ice berg.
Scientists are divided over whether recent episodes of calving are alarming indicators of global warming or just normal, isolated local phenomena.
The world's largest ice shelves are the Ross Ice Shelf and the Filchner-Ronne Ice Shelf.
