Winged snails on a one-year diet

[14. February 2006] 

The winged snail Clione limacina, a small mollusc floating in the water, is able to go without food for a whole year. Investigations at the Alfred Wegener Institute for Polar and Marine Research demonstrate that the snail’s ability to survive extended periods without nutrition is based on a combination of an extremely low metabolic rate, the breakdown of body cells and the utilisation of special lipids.

Successful completion of deep ice coring in the Antarctic

[20. January 2006] 

On January 17, 2006 an international team of scientists and technical staff under the leadership of the Alfred Wegener Institute for Polar and Marine Research has successfully completed the deep ice coring at the Alfred Wegener Institute’s Kohnen Station in Dronning Maud Land, Antarctica. Reaching a depth of 2774 metres, first on-site examinations of the ice core indicate that the ice cored at the deepest 200 metres is very old.

Scientists expect increased melting of mountain glaciers

[19. January 2006] 

Sea level rise due to increased melting of mountain glaciers and polar ice caps will be much lower in the 21st Century than previously estimated. However, decay of mountain glaciers in due to global warming will be much more rapid than previously thought. These are the major results of a study conducted in cooperation with the Alfred-Wegener-Institute for Polar and Marine Research, which is published in the scientific magazine Nature.

Ice harmonies

[25. November 2005] 

Vibrations originating from an iceberg were recorded seismographically at the Antarctic Neumayer Station by scientists of the Alfred Wegener Wegener Institute for Polar and Marine Research and ‘Fielax’, a private business. The recorded vibrations produce harmonic sounds with up to 30 overtones. However, the sounds are not audible to the human ear because of the tones’ low register. The data might facilitate a better understanding of the processes in volcanoes where vibration patterns are similar.

Close coupling of climate with green house gases in the past

[25. November 2005] 

Never before during the past 650,000 years, have concentrations of green house gases been as high as today. The warm climate periods between 650,000 and 420,000 years ago were characterised by even lower carbon dioxide and methane concentrations than subsequent warm periods. This is one of the conclusions drawn by a European team of researchers with contribution from scientists of the Alfred Wegener Institute for Polar and Marine Research, after analysis of an ice core from Antarctica. The results extend previous data on historic concentrations of carbon dioxide, methane and nitrous oxide in the atmosphere by 250,000 years.
