Common Sea Good, my project for our Mother Sea

There are two good reasons to proceed

First, because we have to find new food resources :

For the soon to be 9 billion individuals, our food production needs to increase drastically. It is easily understandable that broad spare areas and quality water in quantity is the least we will need. On the contrary, as desertification and urbanization progresses, available arable lands shrink dramatically. Remaining forests and wild lands are either highly coveted or already acquired. Fresh water is hit by scarcity or pollution, and most of the coastal seas are not even free for new exploitations anymore.
So where are there still enough space and water? On High Seas!

 Let us take a look at all issues we may encounter

Weather conditions are the first issue encountered when operating any infrastructure on high seas. So let us first choose the only ocean not to be prone to cyclones, typhoons or other hurricanes, South Atlantic. Besides, it is the poorest ocean both in terms of fisheries and maritime traffic, so we should find an unoccupied and safe place there.

I managed to found a suitable guyot in the Vitoria Trindade Chain, east of Brazil, the Davis Bank. It rises from 4000 meters on the sea floor to less than 50 meters depth (160 feet), and has a very large flat top, around 90000 hectares (222000 acres). In the tropical southwest Atlantic, it is the only known suitable seamount, which does not belong (yet) to a national Exclusive Economic Zone (EEZ).

The core of all production in the sea is phytoplankton, which multiplies rapidly, subject to presence of mineral nutrients and light. From there on, a short trophic relationship with an organism, which has a good conversion efficiency, would be the most effective and healthiest way to produce anything.

Sessile filter feeders like mussels are good candidates, because they belong to the second marine trophic level, don’t spend any energy to swim and cannot escape. The very short trophic relationship between primary production of phytoplankton and production of mussels assimilating it, combined with the very pure AAIW quality, are the unquestionable guarantee of the lowest level of anthropogenic pollutants at the end of the production process.
