In future, scientists want to acquire marine biology data with a high resolution in terms of time and space there by means of state-of-the-art sensor technologies. These data will then be available online via the Internet. For instance, climatically and anthropogenically induced changes in the hydrography and ecology of the North Sea will be examined in order to gain a better understanding of and be able to model the mechanisms of changes in the ecosystem due to climate change.
"MarGate" is part of the COSYNA oceanographic research infrastructure coordinated by the GKSS Research Centre Geesthacht and financed within the research field "Earth and Environment" of the Helmholtz Association of German Research Centres. In addition to the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, several nearshore research centres and universities in Germany are involved. This will result in creation of modern infrastructure enabling multidisciplinary and interdisciplinary work in coastal areas.
"Due to the unique location of Helgoland far from the German coast, in the middle of the North Sea, which is strongly influenced by climate change, we see the island as a strategic "hot spot" for marine research," states PD Dr. Philipp Fischer, scientific head of the Alfred Wegener Institute Centre of Scientific Diving and fish ecologist at the Biological Institute Helgoland. "The project gives us the opportunity to conduct experiments not only in the laboratory, but also under water directly in the North Sea over longer periods - which was previously possible only with the help of large and expensive research vessels," explains the dedicated scientific diver. "The island of Helgoland as the site offers us unique opportunities," Prof. Karen Wiltshire, director of the Biological Institute Helgoland that belongs to the Alfred Wegener Institute, is pleased to say.
To be able to meet the research demands of the scientists, the "MarGate" experimental field will be equipped with state-of-the-art technology. In cooperation with GKSS there will be underwater high-speed data line connections, so-called "data nodes", at which - as in the laboratory - measuring equipment and sensors or probes can be hooked up and remote controlled via the Internet for longer periods of time. Plans include, for example, recording small crustaceans automatically in their habitat with a zooplankton camera and at the same time obtaining information on the temperature and salt concentration of the water and the distribution of nutrients. This combination of continuous measurements opens up new ways of recording material flows in the sea and analysing food webs.
Thought has also been given to the power supply. Underwater sockets as well as diverse methods for storm-proof positioning of scientific equipment under water, even at wind force 12, will be tested and developed there in future. "We see MarGate only as the first step of a necessary development in taking marine research to where life in the sea takes place, namely under water," says Fischer. To implement such a project not only scientifically but also in practice, however, first the basic structures have to be installed now. Concrete tetrapods, each weighing six tons, will be put in place at a water depth of up to ten metres. This is made possible by good cooperation with construction companies and engineers that are able to provide the structures and position them precisely under water.

The Alfred Wegener Institute conducts research in the Arctic, Antarctic and oceans of the high and mid latitudes. It coordinates polar research in Germany and provides major infrastructure to the international scientific community, such as the research icebreaker Polarstern and stations in the Arctic and Antarctic. The Alfred Wegener Institute is one of the sixteen research centres of the Helmholtz Association, the largest scientific organisation in Germany.

Understanding animal social networks can aid wildlife conservation
23.06.2017 | Leibniz-Institut für Gewässerökologie und Binnenfischerei (IGB)
An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
