Fifty years of sampling at Heligoland Roads: Marine data for climate modelers, biologists and structural engineers
“Data from the Heligoland Roads marine sampling site are of immense importance for sustainability considerations of future generations.” With these words the Parliamentary State Secretary to the German Federal Minister of Education and Research, Dr. Helge Braun took celebratory the water sample marking the 50th Anniversary of the establishment of the Heligoland Roads sampling series.

Witnesses of glacial melting: marine researchers examine the influence of the rapid rise in freshwater inflow on marine algae along the west coast of Greenland
This year Greenland is experiencing one of the warmest summers in its recent history. This heat wave has meant that an international research team is in the unique position of being able to collect important climate data from the changing Arctic. Until today German and US scientists on board the research ship MARIA S. MERIAN have been studying the extent to which the strong inflow of meltwater into the fjords along Greenland’s west coast are altering the chemical composition of the seawater and thus the living conditions for algae and other…

Methane measurements at low level flight
A team of scientists from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) and the GFZ German Research Centre for Geosciences has just completed an airborne measurement campaign that allowed for the first time to measure large-scale methane emissions from the extensive Arctic permafrost landscapes.

Climate research with maximum added value: radiation researchers from all over the world meet at the Alfred Wegener Institute
The sun is viewed to be the driving force of all life on earth. How much of its energy actually reaches the earth’s surface is being recorded by scientists with the Basic Surface Radiation Network (BSRN), a worldwide network of 54 radiation measurement stations. The measurements taken here were originally intended to investigate the energy flows at the earth’s surface which are responsible for our climate. However, the highly precise data are now not only of interest to climate researchers. Photovoltaic installations, for example, generate more energy if…

Current study in the scientific journal Nature: researchers publish results of an iron fertilisation experiment
An international research team has published the results of an ocean iron fertilization experiment (EIFEX) carried out in 2004 in the current issue of the scientific journal Nature. Unlike the LOHAFEX experiment carried out in 2009, EIFEX has shown that a substantial proportion of carbon from the induced algal bloom sank to the deep sea floor. These results, which were thoroughly analyzed before being published now, provide a valuable contribution to our better understanding of the global carbon cycle.

Just a question of time? The inner clock of polar plankton organisms as a focal research topic of a new virtual Helmholtz Institute
Function and significance of the biological clocks in polar planktonic organisms are the focus of the virtual Helmholtz Institute entitled PolarTime starting July 1st, 2012. It is one of eleven new virtual institutes funded by the Helmholtz Association.

Research vessel Polarstern embarks on its 27th Arctic expedition
This Thursday, 14 June 2012, the research vessel Polarstern will leave Bremerhaven on course for the Arctic. 44 expedition participants from institutions from Germany, Belgium, USA and the United Kingdom will spend around one month at sea. Their main study area is the Fram Strait between Spitsbergen and Greenland where they will conduct long-term oceanographic measurements.

North-East Passage soon free from ice again? Winter measurements show thin sea ice in the Laptev Sea, pointing to early and large scale summer melt
The North-East Passage, the sea route along the North coast of Rus-sia, is expected to be free of ice early again this summer. The forecast was made by sea ice physi-cists of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Associa-tion based on a series of measurement flights over the Laptev Sea, a marginal sea of the Arctic Ocean. Amongs experts the shelf sea is known as an “ice factory” of Arctic sea ice. At the end of last winter the researchers discovered large areas of thin ice not being thick enough to withstand the…
