Description

<p>The subarctic North Pacific Ocean is a high-nutrient, low-chlorophyll area in which nutrients remain undepleted in surface waters throughout the year. In this area, phytoplankton growth is limited by the availability of Fe in seawater. To improve our understanding of primary production in the subarctic North Pacific Ocean, it is important to determine Fe distributions and supply processes for this area. However, Fe distribution and biogeochemical cycling have not been fully clarified, because Fe is a contamination-prone trace metal during onboard sampling and analyses in the laboratory. In this review, we compile information on Fe distribution and supply processes in the subarctic North Pacific Ocean from previous studies, with a focus on the atmospheric transportation of aerosols from continents and lateral transportation from coastal areas as Fe supply processes. Moreover, we discuss future studies that should be undertaken to address knowledge gaps in this research topic.</p>
