| Summary: | The Southern Ocean plays a critical role in the global carbon cycle, accounting for over 40% of the global ocean uptake of anthropogenic carbon dioxide (CO\\(_2\\)). Observations are often localized and widely separated in both space and time, resulting in a heavy dependence on models to characterize carbon fluxes at regional scales in this area. Subsequently, notable discrepancies exist between model and observational results within the seasonal sea-ice zone (SIZ) around Antarctica. Given the important role of atmospheric CO\\(_2\\) in the climate system and its influence on changing ocean chemistry (ocean acidification), there is a need to accurately attribute the causes of change and develop a regional understanding of the CO\\(_2\\) sink/source nature of the Southern Ocean. In this thesis, the carbon cycle in the seasonal sea-ice zone of East Antarctica was investigated across a variety of spatial and temporal scales. In this region a large variability in the drivers and timing of carbon cycling dynamics ... |
