"Warm" water is flowing toward one of Antarctica's biggest ice shelves, which, if it melted, could dramatically raise sea levels.
The Filchner-Ronne Ice Shelf (FRIS) extends over the Weddell Sea in Antarctica. Unlike some other Antarctic ice shelves, FRIS currently appears stable in our warming world. However, previous ocean modeling has shown that relatively warm water from the deep sea could threaten the integrity of this shelf.
