项目摘要

The ocean plays a vital role in sustaining life on planet Earth, both providing us with living resources and regulating our climate. The trajectory of current and future anthropogenically driven climate change will be very substantially controlled by the ability of the ocean to continue absorbing the 93% of excess heat and 30% of anthropogenic carbon entering the atmosphere that it currently takes up. The Atlantic Ocean is particularly important as the Atlantic Meridional Overturning Circulation (AMOC) transports heat northwards, keeping north-west Europe 3 degrees warmer than comparable latitudes in N America and Asia. The heat loss associated with the AMOC facilitates intense solubility-driven uptake of both natural and anthropogenic carbon. The Atlantic also supports spatially and temporally diverse biological communities in the water column and at the seafloor which constitute biodiversity reservoirs, act to store carbon in the oceans, and underpin the marine food web; in essence the ocean's natural capital. We now have abundant evidence that many features of the Atlantic Ocean and its marginal seas are changing, including the strength of the thermohaline and wind-driven circulation, sea surface and interior temperature and salinity distributions, air-sea CO2 fluxes, primary production and nutrient fields. These changes may constitute significant threats, by driving fundamental, but poorly understood, changes in the benefits we derive from the Atlantic Ocean. In an era of rapid planetary change, expanding global population and intense resource exploitation, it is vital that we have internationally coordinated observing and prediction systems so policy makers can make sound evidence-based decisions about the ocean. CLASS will take the powerful synergistic approach of using a range of internationally coordinated observations and world-class numerical models to assess the current status and future evolution of the role Atlantic Ocean systems play in regulating key aspects of ocean services. It will support the UK element of international ocean observing and modelling programmes, prioritising the use of autonomous vehicles and new sensors to improve efficiency, and increase the spatial and temporal coverage of our ocean observations, while reducing dependence on expensive research ships. These underpinning activities will provide a platform for future funding investments for the academic community and contribute key datasets and model outputs that can be used across the UK and global community to address important marine policy relevant questions. Finally, we will create effective engagement activities ensuring academic partners have transparent access to NERC marine science capability through graduate training partnerships and access to shipborne, lab-based and autonomous facilities, and modelling capabilities.

海洋在维持地球生命方面发挥着至关重要的作用，既为我们提供了生物资源，又调节了我们的气候。当前和未来人为驱动的气候变化的轨迹将在很大程度上取决于海洋继续吸收目前进入大气层的 93% 多余热量和 30% 人为碳的能力。大西洋尤其重要，因为大西洋经向翻转环流 (AMOC) 将热量向北输送，使西北欧的温度比北美和亚洲的同纬度地区高 3 度。与 AMOC 相关的热损失促进了天然碳和人为碳的强烈溶解驱动吸收。大西洋还支持水体和海底中空间和时间上多样化的生物群落，这些生物群落构成生物多样性库，在海洋中储存碳，并支撑海洋食物网；本质上是海洋的自然资本。我们现在有大量证据表明，大西洋及其边缘海的许多特征正在发生变化，包括温盐和风驱动环流的强度、海面和内部温度和盐度分布、海气二氧化碳通量、初级生产和营养场。这些变化可能会推动我们从大西洋获得的利益发生根本性但人们知之甚少的变化，从而构成重大威胁。在地球快速变化、全球人口不断增长和资源开发密集的时代，我们拥有国际协调的观测和预测系统至关重要，以便政策制定者能够就海洋问题做出基于证据的合理决策。 CLASS将采取强大的协同方法，利用一系列国际协调观测和世界一流的数值模型来评估大西洋系统在调节海洋服务关键方面所发挥的作用的现状和未来演变。它将支持英国国际海洋观测和建模计划，优先使用自动驾驶车辆和新传感器来提高效率，并增加我们海洋观测的空间和时间覆盖范围，同时减少对昂贵研究船的依赖。这些基础活动将为学术界未来的资助投资提供一个平台，并贡献可在英国和全球社会使用的关键数据集和模型输出，以解决重要的海洋政策相关问题。最后，我们将开展有效的参与活动，确保学术合作伙伴能够通过研究生培训伙伴关系以及船载、实验室和自主设施以及建模能力，透明地获得 NERC 海洋科学能力。
