Advances in marine ecosystem modelling research.

海洋生态系统是地球系统的重要组成部分，地球系统是一套相互关联的物理、化学和生物过程，控制着我们的环境。生态系统不仅对海洋和海洋中的生命的生物地球化学循环很重要，而且对大气也很重要，特别是通过二氧化碳等温室气体和二甲基硫化物(DMS)等气候活跃气体。对海洋生态系统进程的了解和预测能力对于海洋管理和可持续渔业管理的生态系统办法至关重要。我们提出了一个研讨会活动方案，旨在帮助制定更好的海洋生态描述，以适应下一代海洋和地球系统模型。我们将比较和对比英国已经在研究的方法和国际社会正在实施的方法。将在以下方面作出特别努力：(1)浮游生物对高二氧化碳水平的反应，(2)浮游生物功能类型在海洋生态系统中的表现，(3)缩小低营养层和高营养层之间的差距，(4)上层海洋的沼气生产，(5)业务生物物理海洋学。此外，我们还将组织一次国际研讨会，汇聚海洋生态系统建模的所有方面。该方案利用了一项现有倡议，并将改善英国社区与这一领域国际利益之间的联系，使其在利用协同效应方面更具凝聚力、协调性和效率。

Marine ecosystems are an important part of the earth system, the set of interlinked physical, chemical and biological processes that control our environment. Ecosystems are important not only to the biogeochemical cycles of the ocean and the life within it, but also to the atmosphere, in particular through greenhouse gases such as carbon dioxide and climatically active gases such as dimethyl sulphide (DMS). Knowledge of and a predictive capability for marine ecosystem processes is crucial to the ecosystem approach to marine management and sustainable fisheries management. We propose a programme of workshop activities aimed at helping the development of improved descriptions of marine ecology, suited for the next generation of both marine and Earth system models. We will compare and contrast approaches already under study in the UK, with those being implemented by the international community. Particular effort will be put into (1) The response of planktonic organisms to high levels of CO2, (2) the representation of plankton functional types for marine ecosystems, (3) bridging the gap between lower and higher trophic levels (4) biogas production in the upper ocean, (5) operational biophysical oceanography. Additionally we will organize an international symposium bringing together all aspects of marine ecosystem modelling. The programme takes advantage of an existing initiative, and will improve the links between the UK community and international interests in this area and making it more cohesive, coordinated and efficient in its exploitation of synergies.
