On going PhDs

Axel Wohleber (2021-2024)

Director : Roberto Grilli
Funding : ministerial grant
Summary : This PhD thesis aims to explore the possibilities of a newly developed sensor for in situ measurements of water isotopes in the oceans. This tool would be key for studying the freshwater cycle, the interactions between the oceans and the ice shelves, and for understanding the processes responsible for the melting of the ice shelves. The student will work on the validation of the instrument in the laboratory as well and in the (…)

Ailsa Chung (2021-2024)

Directors : F. Parrenin, O. Eisen (AWI, Germany)
Funding : DEEPICE project
Summary : Understanding how ice flows in East Antarctica is of uppermost importance to determine the distribution of age with depth for deep ice cores. One of the most important applications is to produce the depth vs age relationship, hence the first age model, for the Beyond EPICA ice core. This study has also numerous other applications since other deep drilling are projected in the Dome C area with the aim to (…)

Etienne Legrain (2020-2023)

Directors : Frédéric Parrenin and Emilie Capron Funding : HOTCLIM MOPGA project
Summary : Many uncertainties remain about future and past interactions between climate and the carbon cycle, as well as their impact on components of the Earth system, particularly those that are most sensitive to a warming climate (eg ice caps, sea level, ocean circulation). In this context, the warm periods of the Quaternary, the interglacials, can provide useful information since they offer a series of (…)

Alexis Lamothe (2020-2023)

Director : Joël Savarino Funding : ministerial grant
Summary : The 20th century will remain as the anthropocene century. This period, characterized by the upheaval introduced by the massive and large-scale use of fossil fuels, leaves and will leave deep environmental scars from which we are not sure that humanity as we know it will recover. The environmental and ecological emergency is there, in front of our eyes. What actions must we take to reduce our impacts ? What effects will these (…)

Sarah Albertin (2020-2022)

Directors : Slimane Bekki (LATMOS) et Joël Savarino Funding : ministerial grant
Summary : This thesis is part of the international ALPACA-CASPA project, the purpose of which is to study urban pollution in polar environments. ALPACA-CASPA addresses key issues on the processes governing the formation, composition and distribution of aerosols in the Arctic (from local and remote sources) in order to reduce uncertainties in predictions regarding the oxidation of aerosol precursors, formation (…)

Albane Barbero (2018-2021)

Directors : Roberto Grilli and Joël Savarino Funding : ministerial grant
Summary : High southern latitude regions present specificities that are highly relevant for studying the climate in connection with the atmospheric chemistry. These regions are very sensitive to the global change : appearance and growth of the Antarctic ozone hole (1), rapid change of the sea-ice (2), rapid increases of temperature (3), changes in precipitation mass balance (4), etc. Contrary to regions of the rest of (…)
