Southern Ocean Carbon and Heat Impact on Climate, SO-CHIC

The Southern Ocean regulates the global climate by controlling heat and carbon exchanges between the atmosphere and the ocean. Rates of climate change on decadal time scales ultimately depend on oceanic processes taking place in the Southern Ocean, yet too little is known about the underlying processes.

To contribute to reducing uncertainties in climate change predictions, the overall objective of SO-CHIC is to understand and quantify variability of heat and carbon budgets in the Southern Ocean through an investigation of the key processes controlling exchanges between the atmosphere, ocean, and sea ice. This is done using a combination of observation and modeling methods. To increase understanding of the global climate, new and old observations will be brought together, together with new specific modelling efforts developed by different European research groups.
