Brief description of the Project:
This project is aimed to evaluate the potential of carbon storage in the upper-mesopelagic layers in the tropical East Indian Ocean under global warming with multiple disciplinaries. A high-resolution 3D physical-ecological coupling model will be established to simulate the dynamic process of DOM in the tropical East Indian Ocean. The mechanism of the forced movement of fresh water and wind by the monsoon and dipolar process on the primary productivity will be detailed explored by models and long term observations. We will try to elucidate the coupling relationship between plankton/microbial community structure and dissolved organic matter composition in the upper-mesopelagic layers. The dynamic/characteristics and accumulation mechanism of dissolved organic matter under the ecosystem structure of tropical East Indian Ocean will be developed. The achievement of this project is helpful to in depth understanding of the regional oceanic science and the knowledge of the interactions between ocean system and climate change.
Region(s) of study:
The proposal is focused on East Tropical Indian Ocean, as specify the exact region, please refer to Zhang et al., (2023), supported by NSFC Shiptime Sharing Project. Traditional physical (S, T, velocity), chemical (DO, DOC, POC (some layers only), CDOM, FTICRMS) biological parameters (phytoplankton composition, Chla, microbials) will be investigated during the field observation. Some targeted incubation experiments (e.g. dilution effect on DOM composition; upwelling effect on DOM & microbial interaction etc.) will be carried out during the cruise.

Data and samples were collected onboard of R/V "Kexue" or "Xiangyanghong" implementing the open research cruises supported by NSFC Shiptime Sharing Project in autumn of 2023 and spring-summer period of 2024. The coming cruise are still under applying and approval through processes.
