019 The Biological Carbon Pump in the Tropical Pacific Ocean

The functioning and productivity of the Tropical Pacific Ocean, as well as the coupling of major biogeochemical processes within its different oceanic areas, are still the subject of much debate. Predominantly thought of as tightly coupled, N2 fixation and denitrification might be more spatially separated than previously hypothesized, which may greatly influence future global ocean organic carbon export. Hence it is important to thoroughly understand the biogeochemical functioning of the Tropical Pacific Ocean in the context of climate change. Through comparing contrasting areas of the Tropical Pacific, we should produce new insights for identifying and understanding the fundamental interactions between oceanic circulation, biogeochemical cycles and ecosystem functioning. This session will focus on several current issues of interest regarding the coupling/uncoupling between carbon and nutrient (N,P,Si,Fe) delivery and removal processes in the photic layer. These processes control the planktonic community composition, functioning, and ultimately the ability of the ocean to biologically sequester carbon. Island effects, mesoscale activity, spatial coupling/uncoupling of biogeochemical processes may be key aspects of the session. This session aims to bring together researchers from different fields (physicists, biogeochemists, biologists, modellers) working together to provide a better understanding of the biological carbon pump in the Tropical Pacific Ocean.
