Description:Satellite estimates of ocean primary productivity (i.e., the rate at which marine algae transform dissolved inorganic carbon into organic material) showed higher values for 2022 (relative to the 2003-21 mean) for five of the nine regions investigated across the Arctic. All regions continue to exhibit positive trends in primary productivity over the 2003-22 period, with the strongest trends in the Eurasian Arctic and Barents Sea. Broad regions of lower-than-average primary productivity during 2022, particularly for the Beaufort Sea, East Siberian Sea, Greenland Sea, and Baffin Bay (associated with higher-than-average sea ice cover in these regions), contributed to the high variability of primary productivity over both space and time across the Arctic.
