The rise in anthropogenic CO2 is altering global climate and we must improve our predictive capabilities to decide on optimal societal responses. The ocean plays a critical role in regulating Earth's climate by controlling atmospheric CO2 and redistributing solar heat. Studying the distribution of trace elements and isotopes in seawater provides important tools to quantify carbon fluxes and circulation in the ocean and their impact on climate change, while studying the distribution of trace elements and isotopes in marine sediments provides the needed temporal context to distinguish between man induced climatic trends and recurring natural cycles.

人为二氧化碳的增加正在改变全球气候，我们必须提高我们的预测能力，以决定最佳的社会反应。海洋通过控制大气二氧化碳和重新分配太阳热量，在调节地球气候方面发挥着关键作用。研究海水中微量元素和同位素的分布为量化海洋中的碳通量和循环及其对气候变化的影响提供了重要工具，而研究海洋沉积物中的微量元素和同位素分布则提供了区分人为气候趋势和反复出现的自然周期所需的时间背景。
