The presence of enormous floating glacial ice plates that are connected to the ice sheet and nourished by snow accumulation is a significant glacial feature of Antarctica. They are known as ice shelves.
An ice shelf is a sizable ice platform that develops as an ice sheet or glacier flows down to a coastline and onto the water's surface. Antarctica, Greenland, Northern Canada, and the Russian Arctic are the only places where ice shelves exist. The grounding line is the line separating the floating ice shelf from the anchor ice that feeds it and is resting on bedrock. Ice shelves can have a thickness of 100 to 1,000 meters. Around the Antarctic continent, it can also be found in the Southern Ocean.
