An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland, Northern Canada, and the Russian Arctic. The boundary between the floating ice shelf and the anchor ice (resting on bedrock) that feeds it is the grounding line. The thickness of ice shelves can range fro… Webiceberg, floating mass of freshwater ice that has broken from the seaward end of either a glacier or an ice shelf. Icebergs are found in the oceans surrounding Antarctica, in the seas of the Arctic and subarctic, in Arctic …
Ice shelf - Wikipedia
WebInteraction between the Amery Ice Shelf and ocean impacts the water mass and circulation. Ice pump is the major mechanism that drives the relative warmer shelf water entering the ice cavity and melting the ice shelf. The cold and saltier water formed by ice shelf ocean sea ice interaction is the potential source for the formation of AABW. WebMost of the meteoric water input must therefore come from glacial meltwater released by melting ice shelves. By integrating over the area of the Amundsen Polynya, we find that … banh duc tau
