Alpine glaciers contribute to carbon cycling
Date:9/17/2012

This press release is available in German.

An international collaboration led by Tom Battin from the Department of Limnology of the University of Vienna unravels the role of Alpine glaciers for carbon cycling. The scientists uncover the unexpected biogeochemical complexity of dissolved organic matter locked in glaciers and study its fate for carbon cycling in glacier-fed streams. Their paper, now published in Nature Geoscience, expands current knowledge on the importance of the vanishing cryosphere for biogeochemistry.

Glaciers are receding worldwide with noticeable implications for the hydrological cycle, including sea-level rise. The potential role of glaciers in the carbon cycle remains poorly understood.

An international research team led by Tom J. Battin, Department of Limnology, at the University of Vienna has been able to unravel the biogeochemical complexity of dissolved organic matter in 26 glaciers in the Austrian Alps. Gabriel A. Singer, in collaboration with researchers from Germany (Thorsten Dittmar, Jutta Niggemann), used ultra-high resolution mass spectrometry to identify thousands of organic compounds locked in the glacial ice. Christina Fasching, together with Peter Steier, Faculty of Physics, Vienna Environmental Research Accelerator, estimated the radiocarbon age of the ice-locked organic carbon at several thousand years. She also determined the bioavailability of ice-locked organic carbon for microbial heterotrophs in the glacier-fed streams. For the first time, the researchers were able to relate, at the compound-specific level, radiocarbon age and carbon bioavailability to distinct molecular groups.

The researchers found that the biogeochemistry of the glacier organic matter is unexpectedly diverse. Phenolic compounds derived from vascular plants or soil dominate, together with peptides and lipids, poten
