Based on the text, what is the connection between phytoplankton blooms and oceanic carbon sequestration?
Marine phytoplankton residing in the photic zone absorb dissolved carbon dioxide through photosynthesis, converting inorganic carbon into organic cellular biomass. When these microscopic organisms die, a significant proportion aggregates into 'marine snow' that sinks into the abyssal ocean. In this bathypelagic depth, carbon remains locked away from atmospheric exchange for centuries, forming a biological carbon pump that regulates planetary climate.
