The present proposal aims at contributing to research fields pertaining to major Earth system science issues: the dynamics of climate, sea-level changes and biogeochemical cycles, all having impact on society's security and welfare. Stable, radioactive and radiogenic isotopes constitute primary tools for the planned studies. They provide access to geological time and to a large array of physical parameters of the Earth system, thus to pre-instrumental and "pre antropogenically-modified" states of this system, hence to the deciphering of natural mechanisms driving the evolution of the Earth, at time scale varying from million years ago, to the present.

本提案旨在促进与重大地球系统科学问题有关的研究领域：气候动态、海平面变化和地球化学循环，所有这些都对社会安全和福祉产生影响。稳定、放射性和放射性同位素是计划进行的研究的主要工具。它们提供了对地质时间和地球系统大量物理参数的访问，从而提供了对该系统的前仪器和“前人为修改”状态的访问，从而破译了驱动地球演化的自然机制，时间尺度从百万年前到现在。
