ArCS项目海洋观测研究主题“主题4：北冰洋环境变化观测研究”，旨在阐明当前北冰洋环境变化的现状和趋势，并评估其对北极海洋生态系统和全球气候系统的影响。为此，我们开展了现场观测、系泊观测、实验室实验、数值模拟和国际合作研究，重点关注太平洋北极地区（PAR）和泛北极的观点。因此，我们发表了一些关于环境变化及其对气候和生态系统影响的科学研究。在本文中，我们对这些结果进行了总结。我们发现了北冰洋及其周边地区水循环、海冰和海洋条件、热输送和海洋混合的物理环境变化。我们还研究了北冰洋的化学性质、碳、循环和海洋酸化。此外，还发表了关于海冰减少对初级生产力影响的新发现。为了向公众推广北极研究，我们与主题6和主题7合作开发了一个教育工具（名为“北极”的棋盘游戏）。
Ocean observation research theme under ArCS project, “Theme 4: Observational research on Arctic Ocean environmental changes”, aimed to elucidate the status and trends of ongoing Arctic Ocean environmental changes and to evaluate their impacts on Arctic marine ecosystem and the global climate system. For these purposes, we conducted field observations, mooring observations, laboratory experiments, numerical modeling, and international collaborative research focusing on the Pacific Arctic Region (PAR) and from Pan-Arctic point of views. As a result, we have published several scientific studies on environmental changes and their impact on the climate and ecosystem. In this manuscript, we compiled these results with some concluding remarks. We found physical environmental changes of water cycle, sea-ice and ocean conditions, heat transport, and ocean mixing in the Arctic Ocean and surrounding areas. We also examined chemical properties, carbon, cycle, and ocean acidification in the Arctic Ocean. In addition, new findings regarding impacts of sea-ice reduction to primary productivities were published. For public outreach of Arctic research, we were able to develop an educational tool (a board game named “The Arctic”) in collaboration with Themes 6 and 7.
