Antarctic Canyons Channel Warm Water, Accelerating Ice Sheet Melting

Antarctic canyons play a critical role in the melting of the East Antarctic Ice Sheet by channeling relatively warm Circumpolar Deep Water to its base, a new study reveals. Led by the National Institute of Oceanography and Applied Geophysics (OGS), researchers discovered sedimentary formations within these canyons, indicating persistent bottom currents that transport ocean heat.
