Sif Island is an island in Pine Island Bay of the Amundsen Sea, in Antarctica. It is 1,150 feet (350 m) long and consists of potassium feldspar granite, mostly covered in ice. It was discovered in February 2020 after the Pine Island Glacier melted away from around it, and is named after Sif, an Æsir goddess associated with the Earth in Norse mythology. It is plausible that the island emerged as a result of post-glacial rebound, a process in which retreating glaciers relieve pressure on the ground, causing it to rise.
