Water mass structure in the eastern tropical Pacific Ocean: Relationship to oxygen variability and geochemical properties


The joint hydrographic and geochemical tracer study of the tropical oceans with focus on the eastern tropical South Pacific are continued to investigate trends of the dissolved oxygen distribution over the past 50 years, as well as present day water mass distribution and currents, and the factors driving nutrient utilization. Additional new foci are decadal-scale oxygen variability, the influence of eddy processes, the relationship of nitrogen and silicon isotope systematics in seawater and particles in the eastern Pacific oxygen minimum zone, as well as intensified model-data comparisons.
