Ailsa Chung’s article about stagnant ice and age modelling in the region of Dome C (Antarctica) was published in The Cryosphere in August 2023. This is the very first article with a DEEPICE PhD student as main author that has been published.

We combined a numerical model with radar measurements in order to determine the age of ice in the Dome C region of Antarctica. Our results show that at the current ice core drilling sites on Little Dome C, the maximum age of the ice is almost 1.5 Ma. We also highlight a new potential drill site called North Patch with ice up to 2 Ma. Finally, we explore the nature of a stagnant ice layer at the base of the ice sheet which has been independently observed and modelled but is not well understood.
