Climate modelling

global sea-level rise of up to seven metres. Moreover, the tremendous amounts of meltwater produced could influence ocean currents, sparking massive changes in the climate, especially in the North Atlantic [...] accurately simulates the past, it can also project the future, paving the way for forecasts on e.g. future sea-level rise or global warming. In this way, these models provide the scientific basis for formulating [...] floodwalls and levees are costly. That’s why it’s important to be able to estimate today how much the sea level will rise, or how much the intensity of hurricanes will increase, tomorrow. Climate modeling

coasts of our seas have always been a natural and constant companion for the inhabitants. However, due to the climate crisis, they can increase dramatically and get out of hand. With rising sea levels and [...] an increase in extreme storms, severe erosion is taking place on many coasts - not only in the North Sea, but also in the Mediterranean.

The excellent scientific infrastructure [...] future, visitors will be able to experience a unique exhibition ranging from the history of the North Sea to the future of marine research. Among other things, the focus will be on an 80,000-litre aquarium [...] researching on Helgoland? What animals and plants live in the waters around the island? How has the North Sea changed over time? And what impact will climate change have right on our doorstep in the future

North Atlantic Deepwater and its precursors

The deep branch of the North Atlantic THC mainly consists of deep-water formed by atmospheric cooling in the Nordic Seas, which overflows the Greenland-Scotland Ridge into the North Atlantic. The Eirik Drift [...] to the poles. The major formation regions of deep and bottom water are the Nordic Seas, the Weddell and the Ross Seas. The Eirik Drift south of Greenland and the Argentine continental margin (red circles) [...] closely downstream of the North Atlantic deep-water formation region and has been shaped by the Western Boundary Undercurrent (WBUC), which constitutes the main part of the deep North Atlantic THC. The sedimentary

100 years of Wadden Sea Station Sylt

The Wadden Sea forms a transitional habitat between land and sea. The shallow depth and constant exchange with the adjacent North Sea create a very special geological space. The Wadden Sea Ecosystem Our [...] Happy Birthday, AWI Wadden Sea Station! When the Wadden Sea Station in List on Sylt was founded 100 years ago, its original mission was to investigate the living conditions of the European flat oyster [...] and how climate change will impact our ecosystem. The Wadden Sea Over the Course of Time With the ‘Sylt Roads’ time series, the Wadden Sea Station in List makes an important contribution to the long-term
