Looking at the nasty algae blooms in Qingdao China wondering if underwater biodigestors could be built utilizing valleys or ice age river coarses possibly preferably in areas that are already anoxic .Don't know if those jellyfish plagues they get could make another feed stock as well as the algae bloom.
Qingdao Algae Bloom Possible Use

http://www.abc.net.au/news/rural/2014-03-11/aus-co-in-us-swine-effluent-biogas-project/5313514 computers aren't my thing if the link doesn't work.
What would be great if you could pump suspended algae blooms in this underwater tented valley and they died and precipitated quickly enough to feed the bacteria at a fast enough rate negating the need for flocculants etc that might be needed at the surface otherwise to increase feed load to the biodegester .Temperature seems to be a big factor so probably going more equatorial even though plenty of places at the equator are still cold down deep

Given what is a mammoth potential scale if this were to be feasible wondering if these methane producing carbon dams could have their discharge be brought up to the surface ( for further algae fertilizing ) and scale might be enough to mitigate cyclone breeding grounds ( bringing the cool water with less energy \ temperature to the surface ) .Natural systems like the Galapagos might offer some more insight into that .

I'm imagining more low flow to no flow recesses for the deep water carbon dam .Stresses on the roof of this would be catastrophic given the surface area ,zones already anoxic would meet with a lot less environmental dispute,don't see the roof being totally sealed so currents introducing flow (more oxygen ) would be problematic as well .I've started imagining a input one side with algae rich warm water (pumped from surface ) on one end having the algae hopefully precipitate out like in a tailings dam they use for mining (slower though of coarse) then many miles away possibly pumping the discharge water to the surface again if it holds (financially viable) nutrients to perpetuate a cycle adding what ever limiting factor nutrients necessary to super charge algae bloom .Said company would probably look for a lease with exclusive fishing rights .
