    I believe, from my reading, that they don't really control any sources,
    but borrow some from neighboring lands, if need be. The control of the
    source (0) in CoA is passed around in the high circles so they can feel
    the power of the land, but they don't have any real power left other than
    name. Perhaps Hermedhie or Khorien of Taeghas allow them a source for
    favors that only the COS can give?

    If you meant the stuff I did, I've not got it on disk, but it might be
    archieved at mpgn? Or perhaps somebosy else has a copy.

    From memory:

    This is based on a rough composite of biodiversity and productivity - I
    don't really see it as being a measure of how 'untouched' an area is,
    since I think that could be pretty unbalancing within the game (since
    almost all marine provinces are going to be unsettled by humans.

    I've put my reasoning for the levels in each section, so people can
    adjust to suit their views of how sources work.

    Oceans: Oceans are marine deserts - there's very little life apart from
    phyto- & zooplankton. A normal Ocean province should provide no more
    than a source level 4.

    Mid-Oceanic Vents: These are the bases for thermosynthetically powered
    ecosystems, which are usually pretty diverse. I'd suggest a very high
    source rating for one of these, but it should be really difficult to
    access - pressure at several miles depth, total darkness, heat all make
    the environment inimicable to humans. Suggested source: 9.

    Coastal Marine Provinces: The productivity of a coastal region is much
    higher than an oceanic province, since alage and animals settle on the
    sea bad, where light can filter down to reach them. Assume a typical
    source level of 6.

    Kelp Forests: I've forgotten how Kelp is distibuted globally - a kelp
    forest would increase a coastal provinces source rating by 1.

    Coastal upwellings: In some regions (there's about 6 - 20 around the
    world I think) deep ocean water rises up to the surface - this is loaded
    with nutrients (Nitrates for the science minded) which allow massive
    production at sea. The best example is along the coast of Peru, which is
    one of the most plentiful fisheries in the world. They're subject to
    twenty-odd year fluctuations when the upwellings stop temporarily - this
    is El-Ninio. and is has pretty widespread effects. I'd suggest a source
    level of 7 for one of these provinces.

    Coral Reefs: Coral reefs are one of the most diverse environments on the
    planet, rivalling tropical rainforests. They're also extremely fragile.
    I'd suggest a base source rating of 9 - however any significant
    disturbance would cause them to drop quickly. I've heard that there may
    be coral reefs of some sort on the bottom of the North Sea - this is
    pretty odd, and I don't really know any details.

    Polar Ice-caps: In spring, when the icecaps melt, they release a lot of
    trapped nutrients - there's then a huge boom in biological production -
    phytoplankton support huge swarms of Kril (several thousand per cc, and
    shoals can be upto several km in size.) These in turn support baleen
    whales, penguins etc.

    Winter: 4, Spring: 8, Summer 6, Autumn: 5

    It should be noted that the North Sea was heavily depleted very early in
    history - Basque (and others) whalers had devastated North-Eastern
    atlantic whale stocks by 1000 AD.
