The pelagic ecosystem plays an important role in cycling carbon between ocean and atmospheric reservoirs. This study explores the hypothesis that widespread extinctions experienced by the pelagic ecosystem at the Cretaceous/Paleogene (K/Pg) resulted in a reduction in surface-to-deep ocean organic carbon (C-org) flux, followed by a long period of recovery (3-4 myr). This hypothesis, coined the ‘living ocean’ model by previous authors, has potential problems. Firstly, benthic foraminifera, which are believed to be dependent on surface-exported food, do not show widespread extinction.
