This causes the sea to rise

On the Nordaustlandet of Svalbard we find the glacier Austfonna. Right now a part of this glacier - the Basin-3 Austfonna - surges for the first time in 140 years. Glaciolog Thorben Dunse from the Department of Geosciences, was interviewed on 16 May in Svalbardposten about the movement in the glacier.

When a glacier surge there is a periodic wave motion in the glacier resulting in a rapid movement forward of the front part of the glacier. For such a large glacier that Austfonna on Svalbard means this a lot of ice that will be released into the sea. The Basin-3 Austfonna will probably loose more ice into the ocean than any other glaciers in Svalbard combined.

Austfonna covers 8,102 km ² (8,492 km ² including Vegavonna) and is the largest glacier in Europe and the eighth largest in the world.

Surge in glaciers are common for glaciers in the Arctic region.
