Coastal marine ecosystems are complex open systems interacting with surrounding watersheds, outer ocean, and the atmosphere, providing a wealth of various ecosystem services to human life. Simultaneously, they are also influenced strongly and often negatively by human activities. Despite occupying relatively small areas, these ecosystems exhibit remarkably high biological productivity and biodiversity, and they provide a wide range of ecosystem services. Building on the fundamental processes of biogeochemical cycles linking land and ocean through rivers, groundwater, and coastal hydrodynamics, this session addresses the structure and functioning of diverse ecosystems such as lakes, rivers, wetlands, estuaries, tidal flats, seagrass and macroalgal beds, mangroves, and coral reefs. Particularly, ecosystem connectivity, linkages among biological communities, resilience and recovery processes, responses to environmental change, and ecosystem services will be discussed. By bringing together researchers from ecology, geochemistry, environmental engineering, and related fields, the session aims to promote interdisciplinary discussions that advance our understanding of aquatic productivity systems from terrestrial to coastal zones, and to develop an integrated perspective on how climate change and human activities influence aquatic ecosystems. This session further seeks to promote knowledge exchange that will contribute to the development and social implementation of sustainable management, conservation, and restoration strategies. We welcome contributions based on theoretical studies, laboratory experiments, field observations, remote sensing, and numerical modeling, covering a broad spectrum of topics including biogeochemical cycling and ecosystem functions, community connectivity, spatiotemporal dynamics of water and material flows, biodiversity conservation, and fisheries resource sustainability.
