海洋的生物碳泵在调节大气二氧化碳水平方面发挥着核心作用。特别是，下沉的有机碳在中层带被分解和呼吸的深度是至关重要的，更深的再矿化作用会导致更大的碳储量。然而，直到最近，还没有在海洋的任何区域建立中大洋有机碳供应和消费的平衡预算，控制有机碳周转的过程仍然知之甚少。大规模的数据综合表明，影响再矿化深度的因素很多，包括上层海洋生态相互作用、内部溶解氧浓度和温度。然而，这些分析并没有提供对再矿化的机械论理解，这增加了对中层碳动态进行适当建模的挑战。有鉴于此，英国自然环境研究理事会资助了一项以机械理解为目标的计划，通过有针对性的实地工作，在IPCC级全球生物地球化学模型中实施了一种新的中层再矿化参数。海洋中远洋内部碳储存控制(COMICS)方案将对中远洋地带的碳循环过程以及这些过程如何影响海洋碳储存提供新的见解。在这里，我们概述了该方案的基本原理、目标、计划的实地工作和模特活动，目的是促进国际合作。
The ocean’s biological carbon pump plays a central role in regulating atmospheric CO2 levels. In particular, the depth at which sinking organic carbon is broken down and respired in the mesopelagic zone is critical, with deeper remineralisation resulting in greater carbon storage. Until recently, however, a balanced budget of the supply and consumption of organic carbon in the mesopelagic had not been constructed in any region of the ocean, and the processes controlling organic carbon turnover are still poorly understood. Large-scale data syntheses suggest that a wide range of factors can influence remineralisation depth including upper-ocean ecological interactions, and interior dissolved oxygen concentration and temperature. However these analyses do not provide a mechanistic understanding of remineralisation, which increases the challenge of appropriately modelling the mesopelagic carbon dynamics. In light of this, the UK Natural Environment Research Council has funded a programme with this mechanistic understanding as its aim, drawing targeted fieldwork right through to implementation of a new parameterisation for mesopelagic remineralisation within an IPCC class global biogeochemical model. The Controls over Ocean Mesopelagic Interior Carbon Storage (COMICS) programme will deliver new insights into the processes of carbon cycling in the mesopelagic zone and how these influence ocean carbon storage. Here we outline the programme’s rationale, its goals, planned fieldwork and modelling activities, with the aim of stimulating international collaboration.
