The tallest rises to a height of 12,600 feet (3,850 meters) the size of the Eiger in Switzerland.
Surveys carried out by scientists at the University of Edinburgh found a range of active volcanoes underneath thick layers of ice.
There are concerns if they were to erupt the amount of magma produced could melt large chunks of the ice sheets.
The volcanoes are located in the area known as the West Antarctic Rift System, which extends for 2,200 miles (3,500 kilometers) from the Ross Ice Shelf to the Antarctic Peninsula, according to a report by Gizmodo. The seepage of meltwater beneath Greenland's and West Antarctica's ice sheets also lubricates ice streams which make them move more quickly into the sea. Only 47 had been previously recorded.
How this discovery of more volcanoes in the Antarctic will impact the world remains to be seen.
It's not now known which of these volcanoes, if any, might be active or whether they could exacerbate the effects of climate change in the area by melting the underside of the ice sheet, causing it to become unstable.

But what does it mean?"We have nearly trebled the number of volcanoes known to exist in west Antarctica", Robert Bingham, from University of Edinburgh, told The Guardian.
And now we return to the discovery's significance to the fate of a planet with a warming climate and rising seas, which depends mostly on the level of volcanic activity beneath the ice.
The arguments in favor of an inactive rift are based on the anomalously low elevation of the WARS compared to other active continental rifts and the relative absence of basalt pebbles recovered from boreholes.
Several previous studies have suggested that the Marie Byrd Land massif is supported by particularly low-density mantle, possibly comprising a volcanic "hotspot".
"The big question is: how active are these volcanoes?".
How many of those volcanoes are active?
