Short summary

The North Pacific oligotrophic ocean gyre (NPOG), with low phytoplankton biomass, covers about 40 % of the North Pacific. The variations in NPOG seasonal cycle, which have a greater impact than its annual mean changes, are influenced by the El Niño-Southern Oscillation from 1998 to 2021. However, from 2021 to 2100, a weakened NPOG seasonal cycle is expected due to climate change. These changes in NPOG seasonal cycle could affect fisheries and marine ecosystems.
