P06 The Southern Ocean: where Ocean, Ice and Atmosphere Meet
Convener: Karen Heywood (Norwich, UK)
Co-conveners: Anna Wåhlin (Gothenburg, Sweden), Andrew Thompson (Pasadena, USA), Roman Tarakanov (Moscow, Russia)
Description
This symposium is open to all with an interest in Southern Ocean sciences and processes, regardless of approach (e.g. theory, modelling, in situ observations, remote sensing). The Southern Ocean influences global climate and plays an important role in the meridional overturning circulation. The interaction of the ocean with the Antarctic ice shelves, leading to ice sheet mass loss affecting global sea level, is a topic of growing emphasis. The role of sea ice and polynyas in mediating interactions between atmosphere and ocean is a key challenge for climate models and for assessing carbon fluxes. This session welcomes results of recent studies such as:
- Southern Ocean mixing and its influence on global overturning
- Antarctic Circumpolar Current and Antarctic gyre dynamics and variability
- cross-slope exchange of heat, freshwater, nutrients and other tracers
- melting and circulation processes beneath ice shelves
- the role of sea ice in water mass formation, air-sea gas exchange and carbon cycling
- atmosphere-ocean interactions, air-sea fluxes and mixed layer physics
- climate model predictions for the Southern Ocean of the future
- techniques and challenges for future Southern Ocean observing systems.
This symposium is co-sponsored by IACS.
