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扮演着至关重要的角色，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对人类过程进行修改的时间和强度，以便将大气二氧化碳稳定在450ppm。我们测量和模拟这个汇的能力是有限的(从测量的和模拟的碳吸收之间的显著差异就可以证明)，目前研究的前沿领域是一套与所谓的生物C泵内较高营养水平行为相关的生物过程。高等生物的这种参与表明，人类活动(捕鱼、能源和矿物开采)有能力影响海洋碳汇，但我们缺乏将直接人类压力和海洋碳储存定量联系起来的能力。海洋ICU将衡量这些关键过程并评估它们的总体意义，将那些重要的过程转换成模型，为气专委的过程提供信息，并以这种方式有助于解决海洋C汇估计的模型数据不匹配问题。我们将把这一信息直接带给缔约方会议，以支持《气候公约》将海洋碳汇纳入全球评估的雄心。我们将使用我们获得的关于生物系统的基本知识来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。这一组成部分将涉及与终端用户和利益攸关方的广泛对话，并产生一个决策支持工具，该工具将使我们能够提出有关50年后如何在变化的海洋中管理渔业和资源开采的问题，从而对我们交付绿色协议的能力做出重大贡献。
