Climate changes brews trouble for marine life in European Seas, Marine Board-ESF report says

06.03.2007
How does Climate Change directly impact on marine ecosystems?

There is no denying that climate changes have profound impacts on the world and especially on the marine environment. Recent research has shown that the Northern Hemisphere has been warmer since 1980 than at any other time during the last two millenniums. As a result the increase in temperature under climate change was generally higher in northern than in southern European seas.

The latest European Science Foundation-Marine Board study report, “Impact of climate change on European marine and coastal environment - Ecosystem approach” shows how even moderate climate scenarios have caused marked consequences on the European marine environment.

The study has detailed the impact of climate change at a European Seas level – in the Arctic, the Barents Sea, the Nordic Seas, the Baltic, the North Sea, the Northeast Atlantic, in the Celtic-Biscay Shelf, the Iberia upwelling margin, the Mediterranean and the Black Sea.

Take the northern Arctic and Barents Seas for example the decline in sea ice cover there has triggered the most obvious temperature-related changes for marine life. The open systems structure of these seas has demonstrated how climate changes are causing further northward movement of marine organisms – Atlantic species are beginning to inhabit the more northern seas, the traditional preserve of Arctic species, and subtropical species are moving into southern waters where previously mainly temperate species existed.

In addition, the increased river runoff and subsequent freshening of the Baltic Sea have also led to shifts from marine to more brackish and even freshwater species while the temperature-induced loss of native species from enclosed systems, such as the Mediterranean and Black Sea, will enhance the introduction of non-native organisms, according to the study-report which is led by Dr. Katja Philippart from the Royal Netherlands Institute for Sea Research.

After taking in all of the recorded impacts on the European Seas for consideration, the ESF-Marine working group has identified other possible future challenges in terms of climate change monitoring, modelling, indicators and research and development. It has made several recommendations based on these challenges.

They are:

1. A concerted effort to gather, store and analyse previously and presently collected marine environmental data (e.g. common open access database and annual Pan-European reporting based on national contributions);

2. Identifying the nature and rate of consequences of climate change in European marine and coastal waters; this will require the maintainance of sustained monitoring efforts and use of new technologies to increase their spatial and temporal resolution;

3. Predicting the consequences of climate change for our marine environment; this will require the development and measurement of parameters.

4. Predicting the response and feedback of marine environments and ecosystems to climate change which would require the improvement of regional climate models and the development of biophysical models;

5. Predicting the impact on climate change on the distribution of marine organisms and on marine food webs; this will require the inclusion of knowledge on species’ physiology, bioenergetics and behaviour in biophysical and ecosystem models.

The study report, which started in 2005, was disclosed today at the annual Young Marine Scientist’s Day event taking place at the Boeverbos venue in Bruges, Belgium, organised by the Flanders Marine Institute (VLIZ). At the event the report was formally handed over to Koen Verlaeckt, head of cabinet ‘Science and Innovation’ of Fientje Moerman, Vice-Minister President of the Flemish Government and Flemish Minister of Economy, Enterprise, Science, Innovation and Foreign Trade.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
