In the marine ecosytem  bioavailability iron (Fe) is one of the most important micronutrient for the marine primary productivity. It plays an important role in the global biogeochemical cycles and the carbon cycle. About 40%~50% of the total surface ocean is High Nutrient Low Chlorophyll (HNLC) owing to limiting of bioavailability Fe. However, research on bioavailability Fe not only involves in the discipline of ocean science, but also has a close connection with atmosphere science, environment science, geoscience, etc. In recent years, the research on it is considered as one of the most important scientific problems in Earth science system and   attracts extensive concerns from the oceanographers and environmentalists. However, there are still lots of challenges and uncertainties existing in models, experiments and field observations. Due to the complicated   Fe in dust, we only summarize the natural sources of bioavailability Fe and detailed   influence factors of bioavailability Fe solubility in this review. Finally, we come up with the suggestions and   reference for our   future work.
