Hallan fuente de calor volcánico bajo glaciar en la Antártida
June 28, 2018 - Al analizar muestras de agua de la Antártida, un grupo de científicos descubrió una fuente considerable de calor volcánico cerca del Glaciar Pine Island.
Elevated levels of helium-3 gas detected in the waters around Pine Island glacier indicate volcanic activity beneath the ice sheet – exhibiting as much as 25 times more thermal energy than a dormant volcano.
The volcanic heat source is one more factor to account for when modelling the stability of the West Antarctic Ice Shelf. The shelf's stability has serious implications for the future of sea level rising.
