Arctic Deep Observation for Multi-sphere Cycling

About 95% of the ocean's carbon is stored in intermediate and deep waters.

The intense dynamic processes of the mid-ocean ridge in the Arctic Ocean results in abundant hydrothermal and cool crustal circulation, which has significantly affected the “slow carbon cycle” of the deep ocean. This project aims to establish an innovative multinational cooperation pattern involving multiple stakeholders, to conduct multidisciplinary and multiscale research on the mass and energy exchange in the lithosphere, cryosphere, hydrosphere, and biosphere of the Arctic Ocean. The project involves assessing the impact of matter cycling between different spheres of the carbon cycle and ecosystem, developing models to predict the response of the Arctic Ocean to global change, and providing solutions and regional management schemes. This project also includes the construction of a transparent database, the optimization of logistics capabilities, and the creation of opportunities for early-career scientists.

This Project is hosted by the Ocean Decade Programme Deep Ocean Observing Strategy (DOOS)
