The impact of the Southern Ocean circulation on climate

The Southern Ocean is a central place in the global thermohaline circulation. It is the only ocean basin that has an open latitude band with no continents, allowing for the existence of the Antarctic Circumpolar Current, the largest current system in the World. The Antarctic Circumpolar Current redistributes tracers such as heat and carbon at the global scale, and isolates efficiently the Antarctic continent from the rest of the World making it the coldest place on Earth.

Recent work also demonstrates that it is a major driver of the Atlantic Meridional Overturning Circulation that influences strongly the North Atlantic climate. As the global climate warms, it is essential to determine how the Southern Ocean circulation will respond because it has the potential to store large amounts of excess heat or carbon, providing powerful feedbacks on the climate system. Through its role on the Antarctic ice sheet stability, its evolution can also have great impact on rates of sea level rise.

Aim of the workshop

The goal of this workshop is to share some of the latest advances in the study of the Southern Ocean, and to foster scientific exchanges and synergies both at the Swedish and at the international level.

Topics of interest for the workshop include

  • Antarctic Circumpolar Current dynamics
  • Frontal structure and eddy activity
  • Water mass formation/transformation
  • Ocean-ice shelf interaction
  • Climate change in the Southern Ocean

Participants

Several prominent international researcher will be present, including 

  • Karen Heywood (UEA, UK)
  • Andy Thompson (CalTech, USA)
  • Gurvan Madec (LOCEAN Sorbonne Uni, Paris)
  • Trevor McDougall (UNSW, Australia)
  • David Marshall (Oxford Uni, UK)
  • Carsten Eden (Hamburg Uni, Germany)
  • Maxim Nikurashin (UTAS, Australia)

Workshop date: Monday 9, 10.00 to Tuesday 10, 16.00, October 2017
