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.

Keywords

Dust, prokaryote, cloud, oxalate, solar intensity, decarboxylation, reduced iron
