Keel Laying for New Research Ship
The Alfred Wegener Institute is setting new standards for sustainability in German maritime shipping. On 8 June 2021 the keel for the successor to the research cut

Wadden Sea Station Sylt
The AWI’s new experimental facility on Sylt makes it possible to simulate the effects of climate change on coastal ecosystems.
