• Climate change will enhance ocean stratification and impact coastal upwelling areas, both leading toreduced plankton productivity. • In turn, in pelagic systems heterotrophic processes will show a significant increase. • Horizontal exchange processes in the tropical and subtropical Atlantic indicate that both sides, i.e., the African as well as South American coastal states need to be considered in Atlantic ecosystem studies. For this purpose, research infrastructure needs to be enhanced and maintained, also with the help of the global North.
