IACS Early-Career Award Winners 2017:

Dr Thorben Dunse, University of Oslo

Dunse, T., Schellenberger, T., Hagen, J. O., Kääb, A., Schuler, T. V., & Reijmer, C. H. (2015). Glacier-surge mechanisms promoted by a hydro-thermodynamic feedback to summer melt. The Cryosphere, 9(1), 197-215. doi:10.5194/tc-9-197-2015.

Citation for Dr Dunse by the 2016 Selection Panel:
“Thorben Dunse and colleagues analyze unique field observations of ice velocity during the onset and development of a surge in one of the drainage basins of the Austfonna ice cap in Svalbard. The data set provides new insights into the yet poorly understood mechanisms of surging glaciers. The authors propose a hydro-thermodynamic feedback that mobilizes stagnant ice initially frozen to the bed, thus leading to fast basal motion and surge initiation. The possibility of such instabilities caused by warming initially cold marginal ice resisting fast drainage may have major implications for ice sheet stability.”

Dr Rachel Tilling, University College London

Tilling, R. L., Ridout, A., Shepherd, A., & Wingham, D. J. (2015). Increased Arctic sea ice volume after anomalously low melting in 2013, Nat. Geosci., 8, 643–646.doi:10.1038/ngeo2489

Citation for Dr Tilling by the 2016 Selection Panel:
“Rachel Tilling and her colleagues assessed variations in Northern Hemisphere sea-ice thickness and volume between 2010 and 2014, and analyzed the drivers of these changes. Results reveal complex spatio-temporal patterns and indicate that Arctic sea-ice is sensitive to modest environmental changes. A pronounced increase in sea-ice volume following a cool summer indicates a resilience in Arctic sea-ice previously not anticipated.”

The 2016 evaluation panel: Regine Hock (Chair), Tómas Jóhannesson, Olga Solomina, and Christine Schøtt Hvidberg.
