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.

本提案旨在为与主要地球系统科学问题有关的研究领域做出贡献：气候动态、海平面变化和生物地球化学循环，所有这些都对社会安全和福祉产生影响。稳定的放射性同位素和放射性同位素构成了计划研究的主要工具。它们提供了对地球系统的地质时间和大量物理参数的访问，从而了解该系统的前仪器和“前人为修改”状态，从而破译驱动地球演化的自然机制，其时间尺度从数百万年前到现在。
