In the subarctic North Pacific Ocean, iron plays a central role in regulating phytoplankton productivity and pelagic ecosystem structure. There are several processes that supply iron from land, shelf sediment and deep waters to the upper ocean. The goal of this workshop is to examine mechanisms of these iron supply processes, including atmospheric deposition of mineral aerosols and combustion substances, lateral transport of coastal iron-enriched waters by eddies and boundary currents, and deep vertical mixing during winter or by strong tidal currents at narrow straits. Such knowledge will be used to identify key biogeochemical pathways that should be introduced into the ecosystem models and to plan international scientific programs for better understanding of marine ecosystem responses to changing iron supplies in the North Pacific.
