Desert Dust Cloud Interactions and Natural Iron Enrichment Mechanism
Abstract
Iron enrichment hypothesis have been tested on many occasions by adding dissolved iron into the seawater. Though Mediterranean Sea never depleted with iron it is one of the most oligotrophic water that exists on earth. It’s shown that oceanic surface chlorophyll levels do in fact regulated by the wet desert dust deposition, independent of the nutritional load of the receiving body. The in cloud alteration of desert dust matrix and its biological content is in fact responsible from the reaction mechanisms initiated via the oxalate released by the prokaryotes. Solar light further enhances the formation of dissolved iron via decarboxylation reaction. Thus this paper explains the pathways of natural iron fertilization mechanisms that can be regulated by seeding the clouds with appropriate desert dust hence offers a means to control the chlorophyll concentration hence control on the negative feedback mechanisms on climate.
