South China Sea Deep
In 2010, the Natural Science Foundation of China (NSFC) funded an 200 million Yuan (~ 30 millions USD) initiative named "South China Sea Deep" - an interdisciplinary research project to study the tectonics, sedimentology and sediment transport, and biogeochemical cycling. PCMSC scientists were invited by colleagues in Tongji University (Shanghai, China) to collaborate on a proposal for studying the deep water sediment dynamics and sediment transport in the northeastern South China Sea. The proposal, "In-situ observation of bottom flows and sediment dynamics in northeastern South China Sea", has been funded for 4 years (2012-2015). A reimbursable agreement is being developed to fund the participation of PCMSC scientists and staff.
PCMSC is invited to participate this project because of our world-renowned research on sediment dynamics and proven expertise in designing and implementing field experiment for sediment dynamic studies from the continental shelves and slopes to submarine canyons. Participation of this project is deemed beneficial to PCMSC in multiple ways:
10/1/11 to 9/30/15
Through in-situ observation of sediment and oceanographic parameters by deep-water mooring and tripod deployments at several key locations, and water column profiling along the transects, as well as sediment and water sampling, the study tries to better understand the following processes that control the bottom circulations and sediment dynamics:
The results from this study, when combined with the analyses and interpretation of existing high-resolution sediment cores, are expected to help understanding the evolution of ocean bottom circulation since the last glacial maximum (LGM), and its control on the formation of the subject high-sedimentation-rate deposit.
For the past 4 decades PCMSC has been at the forefront of sediment dynamics research and had the world-renowned expertise in designing and implementing field experiment for sediment dynamic studies from the continental shelves and slopes to submarine canyons. In this project, we apply this expertise to the northeastern South China Sea where bottom boundary layer studies in deep ocean have never been done before. A decade of fast economic growth has afforded China to substantially increase her investment in ocean science research. A successful collaboration in this pilot project can conceivably extend PCMSC's participation to international projects and strengthen its ocean research capability.
