“Fate of Hydrothermal Iron in the Deep Oceanâ€
Abstract: Iron is a limiting micronutrient in approximately â…“ of the global surface ocean, and it places controls on oceanic primary productivity in the euphotic zone. Major inputs of iron from riverine, glacier/iceberg, atmospheric, sedimentary, and hydrothermal sources enter into the ocean but only a small proportion of the iron is thought to be bioavailable. As a first-order factor, iron that can stay in the water column over long periods of time has increased potential for bioavailability. Physical, chemical, and biological processes that keep iron in the water column-- stabilization mechanisms--represent an essential knowledge gap in current understanding of hydrothermal iron budgets for the ocean. The seminar will focus on the characteristics of particulate iron in the near-vent area of the East Pacific Rise mid-ocean ridge spreading center. The prevalence and implications of iron-organic carbon interactions will be highlighted, and new samples from the recent East Pacific Zonal Transect GEOTRACES cruise will be introduced to examine the relationship between near- and far-field iron-bearing particles.
*The speaker is a candidate for a faculty position in the Department of Oceanography.
