Objectives Global climate changes have been, and will continue altering large scale ocean circulation and coastal processes, and exerting profound impacts on marine environments. The changing basin scale circulation can further shape both regional and global climate, and affect coastal processes through physical and biogeochemical exchanges. The major objective of this symposium is to bring internationally renowned climatologists and oceanographers together to synthesize our current understanding, and discuss future research forefronts in boundary currents and coastal processes within context of global climate changes.

The questions to be addressed in this symposium will include, but not limit to: (1) What are key processes that determine variability of boundary currents in the tropical-subtropical basins ? how do climate changes affect these processes? How does boundary current variability affect climate? (2) What are the main dynamic processes that govern interactions between boundary currents and coastal seas? How does climate variability affect such interactions and change physical and biological states in coastal seas? (3) What are observational and modeling needs to address the dynamics and assess the future changes of deep ocean-marginal sea system?
