Based on satellite data, E. huxleyi bloom contouring, quantification of particulate inorganic carbon (PIC) production and increment of CO2 partial pressure, (pCO2) in surface water were performed. 18-year (2003-2021) time series of these variables are obtained for the Norwegian, Greenland and Barents seas. The bloom areas in the North Atlantic-Arctic water are the lowest in the Greenland Sea varying from 10×103 km2 to (20-40)×103 km2. In the Norwegian and Barents Seas they reach in some years (60-80)×103 km2 and (500-600)×103 km2, respectively. The total PIC content within E. huxleyi blooms rarely exceeds in the Greenland and Norwegian seas 12-14 kilotons and 40 kilotons, respectively. In the Barents Sea, in some years, it can be up to 550 kilotons. The highest level of pCO2 within E. huxleyi blooms in surface waters in the Barents Sea was ~350 µatm...
