On June 8, the United Nations Intergovernmental Oceanographic Commission announced the approved projects of the Decade of Ocean Science for Sustainable Development (the “Ocean Decade”) to mark the World Oceans Day. The International Cooperative Research Program of “Arctic Deep Observation for Multi-sphere Cycling (ADOMIC)” jointly applied by SIO, in conjunction with University of Alaska, Alfred Wegener Institute for Polar and Marine Research, All-Russian Geological Research Institute, University of Oslo, Memorial University of Newfoundland, Sri Lanka National Aquatic Resources Research and Development Agency, Ministry of Blue Economy of Seychelles, Nanyang Technological University of Singapore, China Oceanic Development Foundation was officially approved, and the lead organizer was Academician Li Jiabiao.

The intense dynamics of the seafloor mid-ocean ridge of the Arctic Ocean induces abundant hydrothermal and cold water circulation, which releases large amounts of material elements into the relatively closed ocean, thus profoundly affecting its carbon cycle and ecosystem. In 2019, Academician Li Jiabiao of the Second Institute of Oceanography, MNR began to advocate and organize the “Joint Arctic Scientific Middle-Ocean Ridge Insight Expedition” (the “JASMInE”), which was supported by Institut de Physique du Globe, Paris (IPGP), Alfred Wegener Institute for Polar and Marine Research (AWI), University of Oslo, All-Russian Geological Research Institute (VSEGEI), University of Alaska, Memorial University of Newfoundland, Geological Survey of Canada (CGS), and other internationally renowned scientific research institutions. In 2021, the first integrated geological and geophysical expedition in the high-latitude heavy ice area was carried out at the Arctic Gakkel middle-ocean ridge, setting a number of new international records for Arctic scientific expeditions. On the basis of this international cooperative voyage, SIO and the above international scientific research institutions jointly designed the ADOMIC program. Through a multi-stakeholders based innovative multi-national cooperation model, the program plans to conduct multi-disciplinary and multi-scale research on the material and energy exchange of the Arctic seabed lithosphere, cryosphere, hydrosphere and biosphere, form a new understanding of the deep geodynamic process, magmatic activity, hydrothermal cycle and crustal cold water cycle of the Arctic Ocean ridge, assess the impact of material cycles between spheres on the Arctic carbon cycle and ecosystem, establish relevant models to predict the contribution and response of the Arctic Ocean to global change, and provide solutions to environmental problems and regional management in the Arctic Ocean under the pressure of human activities. Building a transparent Arctic database, optimizing polar logistics support capabilities, creating chances for young scientists to participate in Arctic research, etc. are also part of the program.

As the most important global ocean science initiative launched by the United Nations in the next decade, the “Ocean Decade” (2021-2030) aims to provide scientific solutions to global ocean governance, identify the knowledge for sustainable development, and have a comprehensive knowledge and understanding of the ocean, and enhance the use of ocean knowledge, ultimately forming “the ocean we want” and realizing the sustainable development of the ocean.
