Ocean Chemistry Question

According to what I've read, the iron content in our aquariums should be
almost nil. When I lookied up what it is in the oceans, it was almost nil.
(0.000006 ppm).

Well here is my question for all you geology/chemist brains out there.

If the earth is made up of mostly iron, should there not be a high iron
content in the world's oceans? Why isn't there?

And that is my question of the day.

I am just curious, it is not important for my tank, as I don't even test for
iron.

The crust of the Earth (where the oceans are located) consists mostly of
silicon and oxygen. Iron is a small percentage, less than 10% I think.

Well, first you are way off on your numbers.it is .002 ppm


Second

"If the earth is made up of mostly iron, should there not be a high iron

No

Why isn't there?

Hi Boomer

This link above I found highly fascinating. I'd like to do some further
reading on marine ecosystems and oceanic stuff like the link above, not just
on Iron but general goings on (experiments and stuff. If I go to google
what sort of search strings do I use? Do I just search for marine biology
and hope I get lucky?

About the link above: I think they're playing with disaster if they start
dumping too much iron in the oceans, it might be good for the phytoplankton
but what long term effects will this have on the rest of the oceanic
populations? Dangerous stuff even if it is controlled. Highly fascinating
nonetheless JA?

Marine Biology, yes and you will be buried in links to go through

Here are a couple

I noticed that they stated that the increase in iron caused a decrease in co2.
I heard of a similar experiment where the increase in iron increased bacteria
growth, and actualy increased co2.
