  abstract = {{T}he isotopic composition of precipitation, in deuterium, oxygen 18 and oxygen 17, depends on the climatic conditions prevailing in the oceanic regions where it originates, mainly the sea surface temperature and the relative humidity of air. {T}his dependency applies to present-day precipitation but also to past records which are extracted, for example, from polar ice cores. {I}n turn, coisotopic measurements of deuterium and oxygen 18 offer the possibility to retrieve information about the oceanic origin of modern precipitation as well as about past changes in sea surface temperature and relative humidity of air. {T}his interpretation of isotopic measurements has largely relied on simple {R}ayleigh-type isotopic models and is complemented by {L}agrangian back trajectory analysis of moisture sources. {I}t is now complemented by isotopic {G}eneral {C}irculation {M}odels ({IGCM}) in which the origin of precipitation can be tagged. {W}e shortly review published results documenting this link between the oceanic sources of precipitation and their isotopic composition. {W}e then present experiments performed with two different {IGCM}s, the {GISS} model {II} and the {LMDZ} model. {W}e focus our study on marine water vapor and its contribution to precipitation over {A}ntarctica and over the {A}ndean region of {S}outh {A}merica. {W}e show how {IGCM} experiments allow us to relate climatic conditions prevailing in the oceanic source of precipitation to its isotopic composition. {S}uch experiments support, at least qualitatively, the current interpretation of ice core isotopic data in terms of changes in sea surface temperature. {A}dditionally, we discuss recent studies clearly showing the added value of oxygen 17 measurements.},
