The deep-sea carbon reservoir through geological time

尽管深海碳酸盐是地球上最大的碳库，但深海碳酸盐及其在地球系统中的循环是我们对全球碳循环知识中最重要的缺失环节。该项目旨在利用最近开发的时空计算和模型数据合成工具，追踪过去1.5亿年来深海碳库的演变。该项目将首次严格量化深海碳酸盐中碳的分布和体积，以及它在地球表面和内部之间的通量。它将促进我们对二氧化碳储存和脱气在地质时期的历史和速度的理解，并为公众关于气候变化的辩论提供信息。

Despite being by far the largest carbon reservoir on Earth, deep-sea carbonate and its recycling through the Earth system are the most significant missing links in our knowledge of the global carbon cycle. This project aims to track the evolution of the deep-sea carbon reservoir over the last 150 million years by using recently developed spatio-temporal computational and model-data synthesis tools. The project will provide the first rigorous quantification of the distribution and volume of carbon in deep-sea carbonate, and its fluxes between the Earth’s surface and interior. It will advance our understanding of the history and rate of carbon dioxide storage and degassing over geological time, and inform public debate on climate change.
