dc.description.abstractThe atmospheric supply of iron can modulate ocean biogeochemistry, due to its key role in global nitrogen and carbon cycles, with current estimates predicting up to 20% of global ocean net primary productivity depending on this source. We estimate anthropogenic iron using a detailed technology-based estimation method, resolve it into mineral components, and model soluble iron emissions using various available solubility representation methods including mineralogy. Including metal smelting as a source that emits about 75% of anthropogenic iron, we show that anthropogenic iron emissions are up to 10 times higher in the fine aerosol fraction (<1 µm) than previous inventories. We find that in regions where primary productivity is iron limited, anthropogenic combustion-iron contributes up to half of the soluble iron flux to North Pacific Ocean, but less than 5% to the Southern Ocean. We also find that increasing complexity in representing anthropogenic iron solubility does not necessarily improve model-observation comparison and factors other than under anthropogenic influence largely affect solubility.en_US
