    just as our systems are closed systems, in many ways, on a global perspective the open ocean is also a closed system requiring supplement dosing....just my take on the matter.

    'Fool's gold' from the deep is fertiliser for ocean life

    Debates?
    How does the ocean receive all its dosing needs?

    I don't know much about this, but my suspicion is that iron addition from deep sea vents is tiny by comparison to airborne dust. Dust also falls on the ocean surface, where most of the iron consuming phytoplankton is.

    If the sea floor has been spewing this over billions of years then its a reasonable assumption to make that this is a very probable source of iron and other trace elements.
    The sky is not as dense as the ocean and therefore much lighter particles will end up there, there will be traces of heavy metals, but not as much compared to the ocean.
    IMO, the sky provides mostly carbon....

    There's quite a bit of literature about African dust as phytoplankton fertilizer. [ame="http://www.google.co.za/search?sourceid=chrome&ie=UTF-8&q=african+dust+phytoplankton"]african dust phytoplankton - Google Search[/ame]

    The deep sea definitely has lots of trace elements. Deep sea upwellings are linked to plankton blooms. I just question how much of that nutrient comes from geysers, versus airborne and riverborne inflows.

    A fairy comes by once a day with a Iodine bottle the size of the empire state building and gives it the dose it needs.

    :p

    okay, back that up with some research papers or articles :)
    we wont excuse your theory right away....

    okay that may account for some of the 'fairy dust' but there has to be more :)

    i started this discussion so we can analyse the the oceans sources of nutrients, trace elements etc etc, so that we can understand it and perhaps apply this to our closed systems in a practical way.

    This is a VERY interesting topic :thumbup:

    There would obviously be a constant input of nutrients from the air, from rivers, and from under sea vents, volcanoes, etc, BUT I suspect that most nutrients are merely recycled - fish dies and sinks to the ocean floor, decomposes (if not eaten), nutrients feed bacteria, which feeds small critters, which feeds larger critters, which feeds the next fish... The same biological cycle happens in our tanks, except that the volume of "pollutants" caused by a single small fish dying is enough to overwhelm our systems, and we don't want this to happen as that then causes "ugly" parts of the natural cycle, such as hair algae and cyano growths...
