Arctic marine primary productivity, the fundamental process by which marine algae convert dissolved inorganic carbon into organic material through photosynthesis, forms the foundation of the marine food web and plays a critical role in global carbon cycling. This biological engine is highly sensitive to changes in sea ice cover (see essay Sea Ice), ocean temperature (see essay Sea Surface Temperature), and nutrient availability, all of which are being altered by ongoing Arctic warming. As the Arctic is warming at nearly four times the global average rate (Rantanen et al. 2022), marine primary productivity continues to exhibit complex regional and temporal responses across the Arctic Ocean.
Frey et al. (Mon,) studied this question.
