A place that holds secrets about the origin of life and could provide ecosystem goods and services for the sustainable development of humankind. On the other hand, serious threats to coastal communities and infrastructures from earthquakes and tsunamis are often associated with the volcanism occurred on the seafloor.
High-tech devices and expertise from multiple scientifc areas are necessary to further our understanding of how to solve these coast-abyss interactive threats. To do this, we propose a step-change in deep-sea science through connecting inter-/multi-disciplinary observatories and suveying technologies at various sites in the global ocean.
The coordination will contribute to integrating knowledge on deep-sea ecosystems functioning under global changes, to advancing hazard mitigation from natural hazards and to engaging citizens with the deep ocean that faces a growing pressure from human activities.
