The North Pacific and its marginal seas encompass diverse environments under different influences of climate change and anthropogenic impacts. As a result, these ecosystems exhibit a wide range of characteristics. For example, the primary productivity of North Pacific ecosystems ranges from an extreme oligotrophic to hyper-eutrophic state. Various nutrient limitation conditions can be found as exemplified by the subarctic region, one of the major HNLC regions in the world ocean. While ecosystem regime shifts were first identified in the North Pacific, the change in the primary producer level has not been thoroughly compared and studied in relation to regime shifts. In this workshop, we will review the current understanding of the long-term dynamics and distributional differences of primary producers in the North Pacific. We will also review the factors that determine the primary productivity in different ecosystems of the North Pacific. Differential responses by functional groups will be discussed. Finally, gaps will be identified in using primary producers as a linking element in end-to-end modeling, which is an important component of the FUTURE program.
