An anomalous return of the Odden ice tongue suggests unusual Arctic conditions
Data from many sources, including NASA, have shown a significant decrease in Arctic sea ice since 1979. However, the processes driving the melting and freezing of sea ice are complex, and fluctuations occur throughout the year.
AI Summary
A recent Polar Science study reports that winter sea ice has increased in the Greenland Sea near the West Jan Mayen Ridge, causing the Odden ice tongue to reappear after a period of absence. The authors note that short‑term variations in temperature, winds, ocean convection and water salinity can drive such fluctuations, despite the long‑term Arctic sea‑ice decline documented since 1979. This recurrence may help clarify the processes behind short‑term sea‑ice variability.
