Western Antarctic ice sheet collapse has already begun, scientists warn

Surely testing iron in a silica rich environment amounts to much the same thing as testing iron + silica together, the only difference is that you don't need to add the silica because it's already there....

Many parts of the Ocean are without Silica. Iron on its own will not stimulate a diatom bloom. The Oceans also need Phosphates and Nitrates so unless these key ingredients exist then nothing will happen. Silica also keeps the metal elements safe by preventing them from oxidising so the iron, zinc, magnesium, etc are stable. because they are also nano sized they float around in the higher reaches of the water for longer and are considerably easier to consume. This is why only a small area of the oceans need to be fertilised.

Our friend is jumping on Ironsulphide which comes in large heavy molecules. Not only does it rely on the presence of other elements being already in the water (such as silica) it is very inefficient in how it enters the photosynthesis process which is why so much would be needed.

Cost?

I see Sampath is knocking the aquarium product out at $15 for 100ml. Using your figures, that gives an annual cost of $885 billion or $100 billion more than the total cost of Kyoto. Of course there would be economies of scale and we wouldn't pay retail, but even if we could reduce the cost down by a factor of 100, you could probably add carbon capture to the whole of China for that money ... just think of the Green Taxes you would have to ask for

And I've told you that the silicon issue is moot, also the fertilization process by design increases photosynthesis which releases oxygen, which rises up the water column causing anoxia in the deeper waters, which in turn shifts the bacterial population towards those that produce methane and NO2, both of which are stronger greenhouse gases than CO2 ...

The amount of product needed to treat aquariums is tiny . The manufacturers make very little out of it whereas the retailers simply water it down and coin it. The original product costs €14 per litre I litre broadly speaking will treat 10 million litres of water

The original product costs €14 per litre

So, a global cost per annum of just $82,299,994,000? Or $11 from every person on the planet every year?

how did you work that out?

[pjclarke]

Assuming 1l = 1 Kg to a first approximation. It can't be cheap to manufacture all those light as a feather nano-molecules and embed them in silica....

BTW what proprtion of the ocean is sufficiently silica-deficient to make a difference between iron-only and iron + silica?

How would I know?

I am sure they will do you a deal and employ some cheap local to unpick the silica bits out of the molecules for you!
How many litres shall I put you down for? Good luck getting it past the Scientists

cos you said 'Many parts of the Ocean are without Silica.'

Erratum, I see the price of the solid product is just 300 Rupee / Kg. About 5 bucks. So you can save the world for a bargain $2.32 per person per year.

I said "many parts" not exactly how much.

At last you have done something useful - you have reduced the price for saving the planet

[pjclarke]

Which is why I asked, wondered if you really knew or were just winging it.

Maybe there's a reason the focus for research is on using biologically available iron in the Southern Ocean, maybe all those studies showing OF is of limited utillity have a point ....

Does Global warming cause less or more drought?
