TI  - How the study of water stable isotopes measurements in vapour helps understanding the dynamic of water cycle in East Antarctica
BT  - 27th IUGG General Assembly, 8-18 July 2019, Montréal, Canada
N2  - Recent Monitoring Studies Have Evidenced The Added Value Of Water Stable Isotopes Composition Measurements In Air Dynamics Studies (Atmospheric Circulation), Providing An Integrated Tracer Of The Atmospheric Water Cycle. Water Vapour Isotopic Composition Carries A Fingerprint Of The Oceanic Evaporative Flux, Which Depends On Local Meteorological Conditions, And Reflects Fractionation Processes Occurring Along Atmospheric Transport Pathway And At Precipitation Sites. Our Study Is Focused On Those Processes, As Well As Snow-air Exchanges, Motivated By The Need To Better Understand The Drivers Of Water Vapour Isotope Variations, In Both Vapour Or Surface Snow, In East Antarctica.  We Present Here New Data Of Water Vapor Isotopic Composition From Two Sites In East Antarctica (Dumont D’urville In Coastal Antarctica And Dome C On The East Antarctic Plateau). These Two Sites Have Different Characteristics: Dumont D’urville Is Under The Influence Of Katabatic Wind While The Flat Relief At Dome C Prevents The Existence Of Any Katabatic Wind, Dome C Is A Clear Sky, Dry And Cold Place. However, Both Sites Are However Related Since Dumont D’urville Is On The Main Pathway Of The Oceanic Air Masses Reaching Dome C. After Several Successful Summer Seasons On Both Sites, We Measure Continuously Water Stable Isotopic Composition Of Vapour In Low Atmosphere Using Laser Spectrometers, In Parallel, At Both Sites Since November 2018. We Focus Here On The First Results Obtained Since The End Of 2018 With A Comparison With Previous Summer Campaigns Obtained In Different Contexts (Presence Vs Absence Of Sea Ice On The Coastal Station).
