Volcanoes that occur underneath glacial ice sheets are known by the term "Glaciovolcanism", or subglacial volcanoes. An article published in 2017 claims that researchers from Edinburgh University recently discovered 91 new volcanoes below the Antarctic ice sheet, adding to the 47 volcanoes that were already known. As of today, there have been 138 possible volcanoes identified in West Antarctica. There is limited knowledge about West Antarctic Volcanoes due to the presence of the West Antarctic Ice Sheet, which heavily covers the West Antarctic Rift System -- a likely hub for volcanic activity. Researchers find it difficult to properly identify volcanic activity due to the comprehensive ice covering.
