Development of the subject and organisation of the work: One of the fundamental questions linked to climate change is the quantification of its impact on glaciers and polar ice caps. In the last twenty years, a significant acceleration of coastal glaciers retreat has been measured in Greenland. Quantifying and locating the ice mass loss of these glaciers, half of which is due to iceberg calving, is therefore a major challenge. In addition, there is a strong link, but still poorly understood, between iceberg calving and glacier dynamics, with calving sometimes leading to a significant acceleration in ice flow (Figure 1). The objective of this thesis is to make a breakthrough in the quantification of the spatio-temporal evolution of iceberg calving in polar regions by combining numerical simulation of iceberg calving and glacier dynamics in fluid and solid mechanics with seismological inversion methods.
