The fertilisation of atmospheric aerosols, which promotes ocean biogeochemical activities in the low productivity waters of the earth, plays an important role in global iron, nitrogen, and carbon-biogeochemical cycling. Through the aerosol deposition process, macro and micro nutrients, such as N, P, and Fe, become available and stimulate ocean biogeochemical responses. For several decades, research on the aerosol nutrient supply has focused on desert dust. Meanwhile, it has been suggested that volcanic dust is a much-neglected aerosol source which may also provide nutrients to stimulate ocean biogeochemical responses. Research on volcanic fertilisation is still in its infancy, and very little real world evidence has been obtained. This is especially true for the Low Nutrient Low Chlorophyll (LNLC) waters, since most current results report on findings over the High Nutrient Low Chlorophyll (HNLC) waters. In May 2003, the Anatahan volcano in the Northern Mariana Islands erupted for the first time in recorded history. As it strategically locates in one of the most oligotrophic LNLC ocean deserts on Earth, i.e., the western North Pacific subtropical gyre, this motivated us to use satellite remote sensing and laboratory experiment to search for evidence of volcanic fertilisation over the LNLC waters. Our results based on the 2003 Anatahan event suggest that through provision of Fe and P, volcanic aerosols could indeed make significant contribution to stimulate biogeochemical activity in the LNLC water.
