The abundance and distribution of Earth's water and soil resources are strongly influenced by the spatial and temporal variability of climatic parameters. Thus, there is a need to understand how climate change, whether of natural causes or induced by human activity, impacts fluvial and soil systems. This project will use novel isotopic techniques to study the links between climate variability, chemical weathering, which produces soil, and sediment transport, which affects fluvial systems and water resources. The composition of stable lithium, boron and calcium isotopes, and of radioactive uranium-series isotopes in sedimentary records will shed new light on our understanding of these processes.

地球水资源和土壤资源的丰富程度和分布受到气候参数的时空变异性的强烈影响。因此，有必要了解气候变化，无论是自然原因还是人类活动引起的气候变化，如何影响河流和土壤系统。该项目将使用新的同位素技术来研究气候变化、产生土壤的化学风化和影响河流系统和水资源的沉积物迁移之间的联系。沉积记录中稳定的锂、硼和钙同位素以及放射性铀系同位素的组成将为我们对这些过程的理解提供新的线索。
