METHOD FOR SELECTION OF APPROPRIATE LOCATION TO REDUCE THE ATMOSPHERIC CARBON DIOXIDE THROUGH LARGE-SCALE IRON FERTILIZATION WITH LESS ACCUMULATION RATE OF VOLCANIC SULFUR COMPOUNDS

摘要

The objective of the present invention is to show that HNLC (high-nutrient-low-chlorophyll) regions may be formed by locking iron as sedimentary FeS/FeS₂ at their hypoxic deep oceans in terms of sulfur compounds available from volcanic eruptions to be isolated from surrounding Oceans by Currents and Winds. Other 3 possible regions of LNHC (low-nutrient-high-chlorophyll), HNHC (high-nutrient-high-chlorophyll) and LNLC (low-nutrient-low-chlorophyll) are also explained by the relative degree of the accumulation rates of iron and sulfur, which implies the importance of desolate areas of deserts and volcanoes for the living organisms on Earth. Appropriate locations and schemes for large-scale sequestration of atmospheric CO₂ are suggested to be far from volcanoes, earthquakes and boundaries of tectonic plates for less availability of sulfur compounds.
