报告摘要：
北极异常增温和海冰快速减退是当今北极快速变化的两大主要特征。极地生态系统具有敏感性和脆弱性，其对环境剧变的响应和适应是全球变化研究的热点和前沿问题。本报告将从北极系统科学视角出发，探讨北极快速变化背景下的关键物理过程变异及其对冰藻-浮游-底栖耦合生态系统的影响，深入剖析极地生态系统各个环节对海冰快速减退的响应过程和机理。
Abstract：
In recent decades, abnormal warming and dramatic sea ice loss have been two essential features of the Arctic’s rapid changes. Polar marine ecosystems are sensitive and fragile, and their responses and adaptation to environmental variability are hot topics in global change research. From the Arctic system science point of view, this talk will present critical physical variations occurring in the Arctic Ocean and their impacts on the coupled sympagic-pelagic-benthic ecosystem and further discuss the processes and underlying mechanisms of these ecological changes.
