An ice shelf is a thick, floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface, typically in Antarctica or Greenland.
The boundary between floating ice shelf and the grounded (resting on bedrock) ice that feeds it is called the grounding line.
When the grounding line retreats inland, water is added to the ocean and sea level rises.
