New island discovered in Svalbard

Climate change is altering the landscape of Svalbard at an accelerating pace. Satellite images from this summer reveal that a new island has emerged from beneath Svalbard’s largest glacier, Austfonna, as the ice has melted away.

The Norwegian Polar Institute announced this in a press release.

The small island—roughly the size of Frogner Park—is a new addition to Svalbard’s many Arctic islands. Located off the southeastern coast of Austfonna in Harald V Land, it was previously connected to the mainland by the glacier; however, the glacier has since retreated, opening up a strait between the island and the main ice mass.

"We first spotted it about a month ago in satellite images taken this summer," says Geir Moholdt, a glaciologist at the Norwegian Polar Institute.

The fact that there is now a gap of several hundred meters between the front of Austfonna and the island suggests that warm ocean water is the primary cause—a finding consistent with the ocean warming observed east of Svalbard in recent years. There are strong indications that this trend will continue.

"Svalbard’s glaciers are retreating onto land. As they pull back, fjords lengthen, and the glaciers will eventually be situated entirely on land. At the same time, they are thinning due to warmer summers characterized by significant melting. In recent years, Svalbard’s glaciers have lost an average of more than a meter of surface ice annually. That is far more than what has been observed previously," Moholdt points out.
