项目摘要

The fast decline of Arctic sea ice in the last decades is commonly viewed as manifestation of the climate change. The sea ice reduction exposes a large area of the previously ice-covered Arctic Ocean to the atmosphere, and intensifies air-ocean exchanges. This leads to changes in ocean circulation and impacts ocean ecosystems. Due to multiple influences between ocean and sea ice the future state of the Arctic ecosystem is not well understood.The proposed project will address changes in the ocean currents in the Arctic Ocean and the regional differences the marine ecosystems between the two provinces in the Arctic Ocean: the Atlantic and Pacific sectors. Using historical data, new observations and high-resolution ocean and ecosystem models the project will investigate current changes in the ocean currents, nutrients supply and ecologically important key substances, such as CO2. The data from the "Multidisciplinary drifting Observatory for the Study of Arctic Climate" Observational Programme (MOSAiC; see also http://www.mosaic-expedition.org/) will be used. The programme is planned to take place in 2019/2020 and will cover a large part of the Eurasian Basin and central Arctic.The project will examine nutrient supply to the upper ocean and the changes in marine ecosystems in the future climate change scenarios for the next assessment of the Intergovernmental Panel on Climate Change (IPCC) and will quantify the impact of the emerging new Arctic climate on the ecosystems, fisheries, Arctic industries and societies. The project brings together leading researchers from the UK, Germany and Sweden, building on the research expertise in the Polar Sciences. The project will facilitate a new understanding of the Arctic and climate in the UK, Europe and worldwide.

在过去几十年中，北极海冰的快速下降通常被视为气候变化的体现。减少海冰使以前冰覆盖的北极海洋的大片面向大气中，并加强了海洋的交流。这导致海洋循环发生变化并影响海洋生态系统。由于海洋和海冰之间的多种影响，北极生态系统的未来状态尚不清楚。拟议的项目将解决北极海洋电流的变化以及北极海洋两个省之间海洋生态系统的区域差异：大西洋和太平洋部门。使用历史数据，新的观察结果以及高分辨率的海洋和生态系统模型该项目将调查洋流，养分供应和生态重要的关键物质（例如CO2）的当前变化。将使用“北极气候研究的多学科漂流观测站”（Mosaic;另请参见http://www.mosaic-expedition.org/）的数据。该计划计划在2019/2020举行，将涵盖欧亚盆地和北极中部的很大一部分。该项目将检查上海洋的营养供应，以及未来的气候变化场景中海洋生态系统的变化，以评估下一次评估气候变化（IPCC），并将量化伊斯兰教范围的emicy acties the Emicy of emicy of emicy of emicy of emicy a emicy of emicy of emicy a emery，北极行业和社会。该项目汇集了来自英国，德国和瑞典的主要研究人员，这是基于极地科学研究专业知识的基础。该项目将促进对英国，欧洲和全球北极气候的新了解。
