OS021:
Trajectories of change in the Southern Ocean
Submit an Abstract to this Session
Session ID#: 8669
Session Description:
The Southern Ocean is a critical part of the Earth system and host to unique and diverse marine ecosystems. The region is experiencing rapid changes as the climate continues to warm: dynamic and thermodynamic processes are affecting sea-ice cover, oceanographic processes, atmosphere-ice-ocean interactions as well as the Antarctic ice sheet. How will these changes alter the Southern Ocean's ability to absorb heat, carbon dioxide and support ocean productivity? Will the changes result in feedbacks that accelerate or slow the rate of climate change? This session will address such questions by assessing recent insights from contemporary and palaeoclimatic observations and models. We solicit integrative contributions that explore topics such as sea ice, ice-sheet stability, biogeochemical cycling, atmosphere-ice-ocean processes and marine food webs. We will also consider contributions that explore the current and potential value of Antarctic ecosystem services and how they can be safeguarded.
