Climate change

Intensification and poleward shift of oceanic boundary currents

Change means greater heat and more winter storms for Asia; Gulf Stream is the exception

The ocean get heat from the tropical regions and release them to the mid-latitudes, especially over the routes of the subtropical western boundary currents. In a warming climate, the subtropical western boundary currents (except the Gulf Stream) are going to be stronger and shifting toward the poles. They will bring more heat and contribute to a much warmer climate over the adjacent regions (e.g.., Japan, China).

Global warming results in fundamental changes to important ocean currents. As scientists from the Alfred-Wegener-Institute show in a new study, wind-driven subtropical boundary currents in the northern and southern hemisphere are not only going to increase in strength by the end of this century. The Kuroshio Current, the Agulhas Current and other oceanic currents are shifting their paths towards the pole and thus carry higher temperatures and thus the risk of storms to temperate latitudes. For this study, researchers evaluated a wealth...


Climate and Vegetation

Siberian larch forests are still linked to the ice age

A new AWI study shows that the flora of the Northern Russian permafrost lags behind the climate often by several thousand years

Larches in the Russian Arctic. These trees just need an active layer of 20 or 30 centimetre to grow in summer. They also withstand very cold temperature.
[24. June 2016] 

The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing only a minimal response in forest composition. In the places where, when considering the air temperature, pine and spruce forests should be growing, Siberian larch trees are still thriving. The cause of this paradox has been tracked using million-year-old bee pollen by scientists at the Alfred Wegener Institute, the University of Cologne, and international partner...


Auszeichnung

Heinz Miller to receive the 2016 SCAR Medal for International Coordination

[21. June 2016] 

Prof. Heinz Miller from the Alfred Wegener Institute has been selected to receive the 2016 SCAR Medal for International Coordination. He "has an outstanding breadth of expertise and scientific contribution across glaciology, geophysics and applications to ice core research", writes the Commitee.

AWI Scientist Antje Boetius honoured

[20. June 2016] 

Professor Antje Boetius, Alfred Wegener Institute, was elected as Fellow of the European Academy of Sciences. Furthermore, she will be awarded the Goldschmidt Medal 2016 due to be presented in Japan.


RV Polarstern starts the Arctic season

New equipment for the AWI - "Gardener"

Expansion of the deep-sea long-term observatory AWI-Hausgarten

[09. June 2016] 

Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) are setting out with the research vessel Polarstern towards Spitsbergen, to use newly developed equipment in the Arctic Ocean. Autonomous instruments on the seabed, in the water column and in the air will complement the long-term measurements of the deep-sea research group. In this way researchers can analyse the climatic changes in the Arctic and their impact on the fauna in the future with higher temporal and spatial resolution.
