The subpolar North Pacific region is one of the highest productive area in the ocean. This region is also characterized by high nutrient low chlorophyll (HNLC) region where iron is a key micronutrient that limits primary production in the ocean. Recent studies suggest that iron supply from the continental shelf in the Sea of Okhotsk potentially plays a substantial role in sustaining primary production in the subarctic North Pacific. On the other hand, paleoceanographic studies revealed that productivity has been dramatically changed in this region associated with the glacial-interglacial cycle. In this paper, I review changes in productivity in this region from the last glacial maximum period to the present and discuss a potential impact of iron transport from subpolar marginal sea to the subarctic North Pacific on the deglacial productivity spike
