Project description The Southern Ocean (SO) influences global water circulation and acts as atmospheric CO2 sink, thus affecting our climate at a global scale. In this region, the input of the trace metal iron [...] iron (Fe) is the primary control of phytoplankton growth and CO2 fixation, thus affecting the biological CO2 uptake of the SO and ultimately global CO2 fluxes. Externally sourced contributions of new Fe [...] ions that looked at the bioavailability of the released Fe by whales, seals and flying seabirds and that directly measured their influence on SO phytoplankton productivity and the potential for carbon
