The interactions between atmosphere and ocean play a key role if we are to understand what governs elements cycles in the ocean and to which extent climate change plays a role in the biological carbon pump.In this context,atmospheric deposition is now recognized as a significant source of macro and micro nutrients to the upper ocean.Natural and anthropogenic changes in climate can alter the atmospheric input of aerosols to the ocean.Understanding how these modifications cause changes in planktonic productivity and food web structure is a key question in environmental sciences,as they may result in altered carbon partitioning and biogenic air-sea gas fluxes.
