The Ocean plays a crucial role in the global C cycle, taking up approximately 25% of the CO2 we emit to the atmosphere, and thus slowing the rate of climate change. The future trajectory of this sink will affect the timing and intensity of the modifications to human processes that we need to undertake in order to stabilise atmospheric CO2 at 450ppm. Our ability to measure and model this sink is limited (evidenced by significant discrepancies between measured and modelled C uptake) with the current frontier area of research being a suite of biological processes related to higher trophic level behaviour within the so called biological C pump. This involvement of higher organisms suggests that human activities (fishing, energy and mineral extraction) has the capacity to affect the ocean C sink however we lack the ability to quantitatively link direct human pressures and ocean C storage. Ocean ICU will measure these key processes and evaluate their overall significance, transferring those that are important into models that inform the IPCC process and in this way contribute to resolving the observed model data mismatch of Ocean C sink estimates. We will take this message directly to the COP in support of the ambition the UNFCCC has to include the ocean C sink in the global stocktake. We will use the fundamental knowledge we acquire around biological systems to evaluate the ability of human interventions in the ocean to alter the carbon cycle and produce management tools that allow the tension between resource extraction and C storage to be addressed. This component will involve extensive dialogue with end users and stakeholders and lead to a Decision Support Tool that will constitute a major contribution to our ability to deliver the Green Deal by allowing us to ask questions around how to manage fisheries and resource extraction in a changed ocean in 50 years time.

海洋在全球碳循环中起着至关重要的作用，约占我们排放到大气中的二氧化碳的25%，从而减缓了气候变化的速度。这个汇的未来轨迹将影响我们需要进行的人类过程修改的时间和强度，以便将大气CO2稳定在450ppm。我们的能力来测量和模拟这个水槽是有限的（证明了测量和建模的C吸收之间的显着差异）与目前的前沿研究领域是一套生物过程中的所谓的生物C泵内的更高的营养级行为。高等生物的参与表明，人类活动（捕鱼，能源和矿物开采）有能力影响海洋碳汇，但我们缺乏定量联系直接人类压力和海洋碳储存的能力。海洋ICU将测量这些关键过程，并评估其总体意义，将重要的过程转移到为IPCC过程提供信息的模型中，并以这种方式帮助解决观察到的海洋碳汇估计的模型数据不匹配问题。我们将把这一信息直接传达给缔约方会议，以支持《气候公约》将海洋碳汇纳入全球盘点的雄心。我们将利用我们获得的有关生物系统的基本知识，评估人类干预海洋改变碳循环的能力，并生产管理工具，以解决资源开采和碳储存之间的紧张关系。这一部分将涉及与最终用户和利益相关者的广泛对话，并导致决策支持工具，这将对我们提供绿色交易的能力做出重大贡献，使我们能够就如何在50年后改变的海洋中管理渔业和资源开采提出问题。
