New Copernicus capability for trophic ocean networks

海洋的生物多样性支持着30多亿人的生计，提供重要的服务，包括食物和养分循环。然而，即使使用了欧洲哥白尼海洋服务（CMEMS）最先进的操作模型，海洋政策和资源管理也没有考虑到最新的科学进展。我们的目标是通过将新数据融合到创新的生态系统模型中，整合海洋生态系统的生物和非生物成分、栖息地和压力源，使CMEMS能够提供为海洋生物多样性保护和食物资源管理提供信息的新产品。NECCTON将连接CMEMS系统中的新模型，从而建立新的能力来模拟更高营养水平、底栖生物栖息地、污染物，并提供气候变化影响的预测。我们将开发和利用新的数据处理链，支持CMEMS使用新的生态系统观测数据，包括来自卫星的新高光谱数据，以及现有的声学、污染和组学数据。我们将通过使用创新的机器学习算法来改进模型和数据同化方法来融合这些新的数据和模型。这些发展将应用于13个案例研究，作为我们影响途径的一部分，与渔业和保护管理人员共同设计，从而展示NECCTON产品的技术准备程度6级。项目目标将由一个由23个世界级组织组成的团队来实现，这些组织拥有所有关键项目组成部分的跟踪记录。它包括CMEMS委托实体和核心开发者，他们将推动CMEMS最终采用NECCTON。项目完成后，NECCTON将为CMEMS提供科学和技术能力，以维持其运营组合中的25种新产品，最终使用户能够对海洋服务的开发做出明智的决定，提高可持续性和保护。

The ocean’s biodiversity supports the livelihoods of over three billion people, providing vital services, including food and nutrient cycling. However marine policy and resource management do not yet consider the latest scientific advances, even when the state-ofthe-art operational models of the European Copernicus Marine Service (CMEMS) are used. Our objective is to enable CMEMS to deliver novel products that inform marine biodiversity conservation and food resources management, by fusing new data into innovative ecosystem models that integrate biological and abiotic components, habitats, and stressors of marine ecosystems. NECCTON will interlink new models in the CMEMS systems, thus building novel capacities to simulate higher-trophic-levels, benthic habitats, pollutants, and deliver projections of climate change impacts. We will develop and exploit new data-processing chains, supporting CMEMS' use of novel ecosystem observations, including new hyperspectral data from satellites, as well as available acoustic, pollution and omicsdata. We will fuse these new data and models by using innovative machine-learning algorithms to improve models and data assimilation methods. These developments will be applied in thirteen case studies, co-designed with fisheries and conservation managers as part of our pathway-to-impact, resulting in the demonstration of Technological Readiness Level 6 of NECCTON products. The project objectives will be achieved by a team of twenty-three world-class organizations with track records for all the key project components. It includes the CMEMS Entrusted Entity and core developers, who will promote the final uptake of NECCTON by CMEMS. On project completion, NECCTON will provide CMEMS with the scientific and technical capabilities to sustain twenty-five new products in their operational portfolio, ultimately enabling users to make informed decisions on the exploitation of marine services, enhancing sustainability and conservation.
