The Wadden Sea of the southwestern North Sea, the world’s largest area of connected intertidal flats, has existed for several thousand years, despite a more or less steady rise of the sea level.
This has been compensated for by transport of sediments into the Wadden Sea from the adjacent offshore waters of the North Sea. There is an ongoing scientific debate about the mechanisms which cause this onshore sediment transport. Coordinated by the Leibniz Institute for Baltic Sea Research in Warnemünde, an international consortium of scientists from the Netherlands, Germany and Denmark has now joined forces and launched the project PACE (The future of the Wadden Sea sediment fluxes: still keeping pace with sea level rise?) to investigate the new hypothesis that the sediment transport through tidal channels is triggered by salinity differences. First computer simulation studies and field observations at several points in the Wadden Sea support this new hypothesis.
The following essential questions will be answered:
1. To which extent are salinity differences between the North Sea and the Wadden Sea responsible for the net sediment transport into the Wadden Sea and how does their effect compare to known processes such as tidal asymmetries?
2. How do these transports depend on the strength of the salinity differences which may in turn be increased or decreased due to climatological changes in precipitation?
3. Will the intertidal flats in the Wadden Sea survive an accelerated sea level rise due to global warming?
The researchers from the Netherlands, Germany and Denmark will mainly apply high resolution, realistic computer simulation models for the Wadden Sea, which are well calibrated to observational data. The models will be used to answer questions such as “what happens to the sediment fluxes if the freshwater flux into the Wadden Sea increases and sea level rise is accelerated?” Focal areas of the study will be the Marsdiep-Vlie-Schiermonnikoog system in the western Dutch Wadden Sea, the waters around the island of Spiekeroog in Lower Saxony, the waters around the island of Sylt in Schleswig-Holstein and the Danish Wadden Sea north of the island of Rømø.
The project had its kick-off meeting on March 6/7 in Delmenhorst (Germany) to coordinate their research and to define the specifications of the model simulations.
The project is jointly funded by the Netherlands Organisation of Scientific Research (NWO) and the German Ministry of Research and Education (BMBF) in the framework of the Georisk part of the 1st transnational call for proposals on Bilateral Wadden Sea Research.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
