Key Points

The study aims to assess how climate warming and declining sea ice affect marine algae productivity in the Arctic Ocean.
Analysis of marine primary productivity data across the Arctic Ocean.
Assessment of factors such as sea ice cover, ocean temperature, and nutrient availability.
Marine primary productivity is showing complex responses linked to changes in sea ice and temperature.
Arctic warming is happening at a rate nearly four times faster than the global average.

Abstract

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.
