Winter ice in the Bering Sea, in the northern Pacific Ocean between Alaska and Russia, is at its lowest level in the past 5,500 years.

Researchers analyzed vegetation that accumulated on the uninhabited island of Saint Matthew over the last five millennia.

According to AFP, they looked at variations in peat layers of oxygen atoms called isotopes 16 and 18, whose proportions over time correlate with atmospheric and oceanic changes and precipitation.

The 1.45-meter peat core, taken from Saint Matthew in 2012, represented 5,500 years of accumulation.

"It's a small island in the middle of the Bering Sea, and it's essentially been recording what's happening in the ocean and atmosphere around it," said Miriam Jones, the researcher who conducted the study at the University of Alaska and then at the US Geological Survey.

The ice in the Arctic and Bering Seas melts in summer and freezes anew in winter, but satellite observations only date back to 1979. The advantage of the new analysis, published in the journal Science Advances, is that it goes back much further in time.

For the Arctic, the reduction of winter ice in recent decades is clear and rapid, in parallel with global warming and the increasing concentration of carbon dioxide in the atmosphere. But the Bering Sea in recent decades has seemed stable, the authors of the study say, with the exception of 2018 and 2019, when a strong reduction was observed. In this study, researchers tried to establish whether the current levels are an anomaly or a trend.

"What we've seen most recently is unprecedented in the last 5,500 years," writes Matthew Wooller, director of the Alaska Stable Isotope Facility, who participated in the analysis.

At this rate, conditions are now favorable for a completely ice-free Bering Sea, the authors conclude, highlighting an effect of consequences on the ecosystem.
