Arctic feedbacks -- Snow and ice processes and sea-ice thickness in different regions

Tildelt: kr 0,14 mill.

This is an application for a post-doctoral fellowship for M. Nicolaus within the Leiv Eiriksson mobility program. The exchange is suggested between the Norwegian Polar Institute (NPI; home institute, Tromsø, Norway) and the University of Alberta (UA, host institute, Edmonton, Canada) for five months in the second half of 2009. M. Nicolaus is currently carrying out post-doctoral research at NPI in the Polar Climate section, with focus on sea ice and snow studies in the EU project DAMOCLES. Main objective of the project is a better understanding of sea-ice processes under changing climate conditions. Additionally, he is involved in different projects monitoring Arctic sea ice and its changes, improving sea ice descriptions in numerical models, and advancin g research cooperation, especially among the Northern Countries, incl. Canada. Both institutions, NPI and UA, have a good expertise in studying physical properties of snow and ice in general. The Norwegian partner is specialized on optical measurements an d energy-balance studies of sea ice in Fram Strait and on Svalbard, whereas the Canadian partner conducts most research on ice-thickness and snow physics on sea and land ice in the Canadian Arctic. Central aspects of the planned exchange are (1) to impro ve our understanding of feedback mechanisms related to optical and other physical properties of sea ice, and (2) the common analysis and interpretation of electromagnetic thickness measurements of sea ice in different regions of the Arctic. Therefore, fie ld data from previous expeditions will be shared, analyzed and published in peer reviewed articles. A joint field campaign will be performed in autumn 2009, and short visits of two additional project partners will be included. M. Nicolaus will be involved with lecturing at the UA based on his expertise on micro-physics of snow and sea ice as well as experience with numerical snow/sea ice models and analysis of ice samples in an ice laboratory.
