Simulating the ocean’s chlorophyll dynamic range from coastal upwelling to oligotrophy
Progress in Oceanography, 2018 Abstract The measured concentration of chlorophyll a in the surface ocean spans four orders of magnitude, from ∼0.01 mg m−3 in the oligotrophic gyres to >10 mg m−3 in coastal zones. Productive regions encompass only a small fraction of the global ocean area yet they contribute disproportionately to marine resources and biogeochemical processes, such ...
