shipping channels and berths fill up with sediment. Thanks to seasonal forecasts prepared by the Alfred Wegener Institute, the Hamburg Port Authority can now prepare for such developments well in advance –

Together with partner schools in Germany, schoolchildren from Aklavik, Canada are helping the Alfred Wegener Institute gather valuable data on permafrost. By doing so, they’re improving the joint understanding
