A new study shows that channels beneath Antarctic ice shelves can trap warm ocean water and accelerate melting from below. Researchers focused on the Fimbulisen Ice Shelf in East Antarctica and found that this process may make even cold regions more vulnerable. The findings suggest current climate models could underestimate future sea level rise.

Scientists discovered that the shape of the ice shelf underside plays an active role in trapping heat. Long channels carved into the base allow small circulation patterns to hold warmer water against the ice for longer periods. This effect increases melting by roughly an order of magnitude in some areas, according to the research led by Tore Hattermann and Qin Zhou.

Warmer ocean drives Antarctic sea ice regime shift

New studies indicate that stronger winds and warming deep ocean water have triggered a sharp decline in Antarctic sea ice since 2016. Previously expanding, the ice reached a record high in 2014 before plummeting to record lows. Researchers link this shift to wind-driven upwelling of circumpolar deep water.

Scientists using deep-diving Argo floats have pinpointed the reason behind Antarctica's dramatic sea ice contraction starting in 2016. The decline stems from a violent release of pent-up heat from ocean depths, triggered by shifting winds and salinity changes. This discovery highlights the ocean's key role in sea ice variability.

Hektoria Glacier collapses rapidly in Antarctica

In 2023, Hektoria Glacier on Antarctica's Eastern Peninsula retreated eight kilometers in just two months, marking the fastest such event recorded. Nearly half of the glacier broke apart due to its position over a flat underwater bedrock. The discovery, detailed in a new study, highlights vulnerabilities in other Antarctic ice features.
