Abstract: 

Southern Ocean phytoplankton are major drivers of global carbon cycling accounting for 20% of the global annual primary production. Most of this production relies on large phytoplankton blooms along the Antarctic continent, while pelagic phytoplankton contributes to a minor degree. Until now, only little information is available on how climate change will affect Southern Ocean phytoplankton communities. The increase in atmospheric CO2 has already caused significantly higher aquatic CO2 concentrations and lower pH values (‘ocean acidification’) compared to pre-industrial times. In situ fertilization experiments have revealed that iron availability is the key factor in controlling Southern Ocean phytoplankton productivity and community structure. Until now, only little information is available on how these environmental factors (CO2, iron) affect Southern Ocean phytoplankton. In particular research on interactive effects of these factors is still scarce. The consequences will, however, most likely differ depending on the region. In the present talk, I will present results from laboratory CO2-manipulation experiments with Southern Ocean key phytoplankton species and will highlight results from shipboard experiments with natural phytoplankton assemblages, in which the combined effect of CO2 and iron was investigated.
