EPOCA: Ocean Acidification and its Consequences on Ecosystems

[26. May 2008] 

The European Project on Ocean Acidification (EPOCA) will be launched on 10 June 2008. Its goal is to document ocean acidification, investigate its impact on biological processes, predict its consequences over the next 100 years, and advise policy-makers on potential thresholds or tipping points that should not be exceeded.

The Antarctic deep sea gets colder - RV Polarstern finished first Antarctic field season within the International Polar Year

[21. April 2008] 

The Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile.

Methane sources over the last 30,000 years – New insights into natural changes in atmospheric methane concentrations

[16. April 2008] 

Ice cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) were now able to identify the most important processes responsible for changes in natural methane concentrations over the transition from the last ice age into our warm period. The study now published in the scientific magazine nature shows that wetland regions emitted significantly less methane during glacial times. In contrast methane emissions by forest fire activity remained surprisingly constant from glacial to interglacial times.

Seven Months on a Drifting Ice Floe - Drift Expedition NP 35 has Produced Unique Data about the Hibernal Atmosphere above the Central Arctic

[14. April 2008] 

For the first time, a German has taken part in a Russian drift expedition. Jürgen Graeser, a 49-year-old scientific technician of the Potsdam Research Unit of the Alfred Wegener Institute, has spent seven months on an ice floe and gained observational data from a region, which is normally inaccessible during the Arctic winter.

The response of marine algae to climate change: Young scientist at the Alfred Wegener Institute gets EU funding in the amount of 1.4 million Euros

[25. March 2008] 

A new project at the Alfred Wegener Institute dealing with the impact of climate change on marine phytoplankton will be funded by the European Research Council ERC with 1.4 million Euros. With his project "PhytoChange" Dr. Björn Rost was among the 3% of successful applicants for the Independent Investigator Grant and succeeded against more than 9,000 competitors from all over Europe.
