The ocean plays a major role in mitigating the impact of climate change, sequestering 20-30% of atmospheric anthropogenic carbon dioxide each year. The Biological Carbon Pump refers to the biological processes that transport oceanic carbon from the surface to the ocean deep. It is a key controller of how much carbon is stored in the ocean, however there are many influences on this system, from food-web interactions to physical and chemical drivers. Understanding these influences and their impact on carbon sequestration is vital in order to improve climate change predictions. This project will therefore use a modelling-based approach to explore and analyse different ecosystem impacts on the functioning of the BCP, both under present day conditions and over the 21st century.

海洋在减轻气候变化的影响方面发挥着重要作用，每年吸收20-30%的大气人为二氧化碳。生物碳泵是指将海洋碳从表面运输到海洋深处的生物过程。它是海洋中储存多少碳的关键控制器，但这个系统受到许多影响，从食物网相互作用到物理和化学驱动因素。了解这些影响及其对碳固存的影响对于改进气候变化预测至关重要。因此，本项目将采用基于模型的方法，探索和分析在当今条件下和世纪对BCP功能的不同生态系统影响。
