4. The Science of Ice Shelf Melt

Warm ocean water is melting Antarctic ice shelves. Physical oceanographer Dr. Elin Darelius explains how the Southern Ocean carries heat beneath floating ice shelves and why that interaction matters for the future of Antarctica’s land-based ice. Learn the differences between ice sheets, ice shelves, sea ice, and icebergs, how oceanographic moorings collect data in extreme conditions, and what scientists discovered by drilling through the Fimbul Ice Shelf. The episode also explores how ice shelves slow the movement of glaciers and why their weakening can contribute indirectly to sea level rise. A clear guide to ice shelf melt, physical oceanography, and the ocean processes shaping Antarctica under climate change.Episode Guest: Dr. Elin DareliusMore information about Dr. Elin Darelius here. Browse Dr. Elin Darelius’ publications on Google ScholarFollow Dr. Elin Darelius’ blog More information on polar research at the University of BergenMore information on the Bjerknes Center for Climate ResearchFind.
