本文以深海为重点，对现有的研究课题进行了总结，并对未来研究的方向和意义进行了探讨。我们将深海的海洋生物地球化学循环作为一个涉及物理、化学和生物学的跨学科课题。我们特别讨论了三个问题：(1)深海到中大洋的输送；(2)表层到深海和中大洋的有机质输送和变化；(3)深海的时间变化。在(1)中，我们讨论了量化太平洋从深层到中间层的输送的相关性，从而将我们的理解从垂直一维视角扩展到三维视角。在(2)中，我们总结了最近提出的有机物泵的新概念，并从过程和模型研究两方面讨论了方法的必要性。在(3)中，我们讨论了除了持续观测外，古海洋学研究和数值模式等多种方法的相关性，以了解未来深海将逐渐发生的变化。
Focusing on the deep ocean, in this article, we summarize the existing research topics and discuss the direction and significance of future research. We focused on the ocean biogeochemical cycle in the deep ocean as an interdisciplinary topic that involves physics, chemistry, and biology. In particular, we discussed three issues: ( 1 ) transport from the deep to intermediate ocean, ( 2 ) transport and changes of organic matter from the surface to deep and intermediate oceans, and ( 3 ) temporal changes in the deep ocean. In ( 1 ) , we discussed the relevance of quantifying the transport from the deep to intermediate layer in the Pacific Ocean to broaden our understanding from a vertical 1D perspective to a 3D one. In ( 2 ) , we summarized the new concept of recently proposed organic matter pumps and discussed the necessity of approaches from both process and modeling studies. In ( 3 ) , to understand the future changes in the deep ocean that will progress gradually, we discussed the relevance of various approaches, such as paleoceanographic studies and numerical models, in addition to continuous monitoring by observation.
