PS44A:
Defining the New Frontiers of Ocean Mixing Research III Posters

Session ID#: 84751

Session Description:
Ocean mixing plays several very important roles in the open and coastal ocean through a variety of different processes. In the upper ocean, mixing influences the sea surface temperature and hence air-sea interactions which in turn impact global climate change; while in the deep ocean, mixing maintains the abyssal stratification of the world’s oceans and impacts the global overturning circulation. Ocean mixing also modulates the transport and dispersal of dissolved and suspended materials including pollutants and fish larvae. Planktonic ecosystems are controlled through nutrient pumping associated with ocean mixing.

     This session encompasses a wide variety of aspects of mixing within the water column from the surface to the seabed, as well as the impact of mixing on key physical, biological, and chemical processes, such as those mentioned above, with special attention to new findings obtained through improvements in oceanographic instrumentation and the use of supercomputers. Observational, theoretical, experimental, and numerical approaches are all welcome. In this session, we particularly encourage discussion that can confirm how far our understanding of related topics has advanced and help define the new frontiers of ocean mixing research to be tackled in the next decade.
