    This is my first post here, and I’ve quietly had this idea for several years, but not felt where to share it.

    Back in my Environmental Studies/Health BA/BS days, I read about (1) deep ocean currents causing nutrient upwelling along certain coasts–nutrients that sustain entire ecosystems, and (2) vast areas of the ocean relatively devoid of nutrients and thus devoid of ecosystems and all but migrating fish..

    I also studied about how much the consumer societies discard, and the challenges of finding enough landfill space.

    Later I heard of a quest (3) to find carbon sinks to mitigate or even reverse the greenhouse effect.

    And all my life I’ve heard of (4) regional and global food shortages.

    That got me to thinking. What if we seeded some of the desert areas of the oceans with (a) nutrients, (b) growth matrix (e.g. tiny, perhaps buoyant particles) for life to grow upon, and even, ultimately (c) lights powered by (d) tidal/wave/solar energy, so that we could (e) grow enormous amounts of plankton and other foods, then, (f) seeded such place with progressively higher niches lifeforms (pants/shrimp/fish/Whales). Further, to accelerate plant and fish growth we could (g) aerate the water to increase ambient oxygen and metabolism.

    On the right scale, such a system could become a huge carbon sink and a huge producer of food.

    Your seasteading societies could earn their keep by running this process and exporting food. You could earn international funding by offsetting carbon credit taxation for your investors…

    You could help humanity to avoid starving and live sustainably.

    You could reverse the greenhouse effect and preserve the glaciers and current coastlines, helping hundreds of millions avoid the cost of relocating.

    What do you think of my combination of ideas?

    I don’t have the necessary background, but judging by what you told us I would say: Your idea sounds great!

    I think you should research your idea and give us a plan so we can start experimenting. I’m always for hands on experience as early as possible.

    A starting point could be:

    • What nutrients do we have to use?
    • How much light do we need?
    • Where can we try this out?

    this is great, i like your way of thinking, but you are talking about creating your own ecosystem in an area of the ocean that curently doesnt support life. its very ambitious, but then this is definately the place for it. id love to talk more. ive actually read a few articles along the same line, in which and ecosystem was created in order to process human waste water. a very interesting article in which it talks in great depths about how hard it is to gain balance in the ecosystem. ill try find it again and post some links

    this isnt the one i was looking for, but its along the same lines http://www.gnest.org/cest8/8cest_papers/abstracts_pdf_names/p65_Jenssen.pdf

    its a bit old, im sure theres something more recent out there, and ill continue to look. obviously the real working of something like this is a bit beyond my knowledge, but with the amount of highly intelligent brains involved in seasteading im sure someone might be able to go a little further with this idea

    It seems like it would be easier to use the nutrients already available in deep seawater than to import them. nutrient rich sea water is a byproduct of OTEC or it can be pumped to the surface with a wave pump. This eliminates the need for the lights. There may some benefit from supplemental feeding such as chelated iron.

    lans like these sound great, but im not sure about the details.

    Most forms of ‘free’ nutrients come in very dillute form: having to transport them makes them not so free after all.

    Then when you have made your investment, how are you going to stop ocean currents and diffusion of running off with it?

    i agree that keeping your nutrients where you want them is going to be a problem. but as for free nutrients, the info i have been researching is talking about re-cycling human waste, which im sure we’re going to have plenty of. also this would eliminate the need for transporting or storing waste by other means. in reality we could produce liquid fertilizer from our waste products, and thats got to be worth exploring a bit more

    Maybe when you have a big sea-city, but a few toilet flushes a day do not do much to impact the ocean.

    i think you might be to easily forgetting the lessons history has taught us about humans ability to only look in the short term. if we are thinking about making seasteading truely viable then we cant just seet up wasteful practices in the begining and hope that someone comes up with a better way to do it at a later date. i mean do we really want to just start simply throwing our waste into the ocean simply because we think “what possible impact could MY small amount of waste do??” or am i just alone in thinking that a seastead could be a template for a more enviromentally friendly way of living?

    i love enviromentalist approaches to food production in ocean but i love it more when its a capitalist approach 😀

    that said; such project in the ocean isnt likely to take place in near future but if seasteads really evolve to colonies then to cities it is by all means a viable option.
