Organic carbon and calcium carbonate are two critical components of the ocean’s carbon cycle. Organic carbon originates mainly from phytoplankton photosynthesis, which is part of a complex biological pump. Calcium carbonate, meanwhile, largely derives from shell-building organisms like coccolithophores, foraminifera, and zooplankton (pteropods). Yet how or if the calcium carbonate cycle interacts with organic carbon in the North Pacific is not well understood.
