The future of the Wadden Sea: Does more rain prevent it from drowning?

02.04.2012
New cross-border project PACE started

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.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
