New research highlights how interactions between ocean currents and the ocean floor, rather than just wind, are crucial in driving the rapid melting of Antarctic ice shelves, posing a threat to global sea levels. Dotson Ice Shelf, Amundsen Sea, Antarctica. Credit: Taewook Park

The study focused on the role of a layer of warm water beneath the frigid surface waters, known as the ‘modified Circumpolar Deep Water,’ in melting these ice shelves from below. “The intensity and trajectory of ocean currents encircling the ice shelves directly govern the influx of warm water, thereby intricately shaping their rate of melting” explains Taewook. This shows the importance of the ocean in understanding and addressing the impacts of climate change.

Ocean currents threaten to collapse Antarctic ice shelves, study findsOcean currents threaten to collapse Antarctic ice shelves, study findsA new study published in Nature Communications has revealed that the interplay between meandering ocean currents and the ocean floor induces upwelling velocity, transporting warm water to shallower depths. This mechanism contributes substantially to the melting of ice shelves in the Amundsen Sea of West Antarctica.
