My research is concerned with the role of sea ice in the climate system, both as an indicator and modulator of changes of atmosphere-ice-ocean processes. In particular, I am interested in changes of the sea ice mass balance as a result of variations of the thermodynamic and dynamic boundary conditions for ice growth, melt, and deformation, including the role of the snow cover. While my studies generally include both Arctic and Antarctic sea ice, the recent focus of my research is the establishment of long-term, systematic ice mass balance observations of thick multi-year ice in the Arctic Ocean between the coast of Canada and the North Pole. These observations will include biannual airborne electromagnetic measurements of the seasonal and interannual ice thickness variability, as well as observations of ice deformation and snow properties. In-situ measurements will be complemented by satellite remote sensing and modelling work, and will contribute to the validation of new satellite products and model results.

我的研究关注海冰在气候系统中的作用，既是大气-冰-海洋过程变化的指示器，也是调制器。特别是，我对海冰质量平衡的变化很感兴趣，因为冰的生长、融化和变形的热力学和动态边界条件的变化，包括积雪的作用。虽然我的研究一般包括北极和南极海冰，但我最近的研究重点是建立长期系统的冰质量平衡观测，观测加拿大海岸和北极之间的北冰洋厚冰多年。这些观测将包括半年一次的季节和年际冰厚变化的机载电磁测量，以及冰变形和雪特性的观测。现场测量将由卫星遥感和建模工作补充，并将有助于验证新的卫星产品和模型结果。
