In-situ measurements and satellite remote sensing of the sea ice mass balance

我的研究涉及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和调节器。特别是，我感兴趣的是，由于冰生长、融化和变形的热力学和动力边界条件的变化，包括积雪的作用，海冰质量平衡的变化。虽然我的研究一般包括北极和南极的海冰，但我最近的研究重点是建立对加拿大海岸和北极之间的北冰洋多年厚冰的长期、系统的冰块平衡观测。这些观测将包括一年两次的季节性和年际冰厚度变化的航空电磁测量，以及对冰变形和雪特性的观测。现场测量将得到卫星遥感和建模工作的补充，并将有助于验证新的卫星产品和模型结果。

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.
