Important external dissolved iron inputs, HNLC water formation and strong biological seasonality explained in the North Pacific Ocean

Subarctic Pacific is known as High Nutrient, Low Chlorophyll (HNLC) area, where phytoplankton growth is limited by dissolved iron (DFe) availability. The biological activity in the surface waters is also characterized by a marked seasonality. Nishioka and Obata (2017, see reference below) propose a detailed DFe zonal section across the North Pacific (~47°N), realized in […]
