Ocean Fertilization by the man-made Sea-Mountains Built with Coal Ash Concrete Blocks

摘要

The underwater sea-mountain using large amount of coal-ash-concretehas been constructed in coastal area of about 100m depths to enhanceprimary productivity due to upwelled mixing of bottom watercontaining more nutrients into the euphotic layer by harnessing tidalcurrent. The man-made sea-mountain can preserve the shallow searegion from which it reclaims land with coal-ash. Marino Forum 21(MF21) became the business proprietor and completed the underwatersea-mountain utilizing 20,000t coal-ash with a height of 12m, 120m ofextension, and a width of 60m in response to the subsidy of theFisheries Agency. The rise of chlorophyll-a concentration wascontinuously checked by the ocean color sensor of satellite SeaWiFS in25km x 25km. The fish catch investigation in the 18km x 20km oceanspace using the specimen fishing boat, the fish catch increased focusingon the sardine and it reached 6 times before structure installation.
