Most of the oceans far from shore is basically a dead desert of sorts.There is not enough iron in the water to start the food chain.Attempts have been made to fertilize the waters,but the iron quickly sinks to the bottom and is useless.
Plastic floats on top of the water,and will not sink,so why not apply fine iron powder to the plastic garbage patches to encourage the beginning of a food chain there?
I have see volley balls with crustaceans growing on them,eventually they will sink and take the stored carbon with them.
The phytoplankton,which are the base of the food chain, merely need a place to start,the rest will follow.
Constructive comments are always welcome.
