This study combines micropaleontology and satellite remote sensing to investigate particulate inorganic carbon in the Pacific sector of the Southern Ocean. We compare estimates of calcium carbonate produced by coccolithophores (tiny marine algae) to satellite measurements of particulate inorganic carbon. Both datasets show good agreement north of the Polar Front, but large differences are observed to the south of it, likely because of highly reflective small opal particles in this zone. 

This study investigates the mechanisms driving anomalous phytoplankton blooms in the East China Sea (ECS) during El Niño decaying summers. The findings highlight three key mechanisms: increased river runoff, nutrient transport through the Taiwan Strait, and wind-driven upwelling, all linked to the western North Pacific anticyclone (WNPAC).
