Short summary
The gravitational sinking of calcified planktonic organisms (CaCO3 shell) participates in capturing CO2 in the ocean. This work reveals that the plankton seasonality seems to be an important driver of CaCO3 flux efficiency. CaCO3 dissolution in the water column is assumed to be responsible for this discrepancy. This review suggests that the type of sinking particles (marine snow aggregates, zooplankton fecal pellets) and the plankton network may affect the CaCO3 export efficiency.

Short summary
The gravitational sinking of calcifying plankton (CaCO3 shell) participates in capturing CO2 in the ocean. This work reveals that plankton seasonality and regional differences are important drivers of CaCO₃ flux efficiency. CaCO3 dissolution in the water column is assumed to be responsible for this discrepancy. This study suggests that the type of sinking particles (marine snow aggregates, zooplankton fecal pellets) and the plankton phenology may affect the CaCO3 export efficiency.
