Anthropogenic addition of CO2 to the atmosphere changes our world. Our ability to predict the effect of climate change depends on our understanding of the functioning and efficiency of the ocean’s ”biological pump”: the amount of particulate organic carbon sinking out from the ocean’s surface layers, and where this carbon is released back as dissolved CO2.
The efficiency of the biological pump is reduced by the rapid attenuation of the sinking POC flux with depth, which is mainly determined by the quality and quantity of sinking particles, bacterial remineralisation and zooplankton consumption and fragmentation of particles.
This network focuses on the efficiency of the biological pump, specifically on the role of the two key zooplankton groups (copepods and appendicularians) in creating and degrading the vertical flux, and how it is affected by changes in temperature and CO2.
The main targets of the network are to foster the exchange of ideas and expertise between the member groups, to conduct joint experiments with a potential for a scientific break-through in the subject area and to facilitate the networking and training of the PhD students and post docs.
