TED, please cite sources to support your statement: "Ocean iron fertilization remains criticized by experts working in this field who have expressed concerns about its environmental impacts." I understand this not to be true. I challenge you to prove me wrong.

You’re 100% right, life needs balanced ratios of several other essential trace elements as well as iron, such as manganese, cobalt, nickel, sulfur, etc. that are major enzyme co-factors, along with the major nutrients, nitrogen, phosphorus, and silica for diatoms.
Volcanic ash is high in all except for nitrogen, but its phosphorus can be quickly depleted.
Unbalanced nutrient ratios lead to unbalanced ecosystems.
Adding iron alone to extremely oligotrophic Pacific waters does not work.
Where steel ships are wrecked on oligotrophic atolls they produce “Black Reefs” where bacterial slime overgrows and kills all the reef fauna and flora.
This does not happen in eutrophic coastal waters with sewage.
Fertilizing with iron ALONE will NOT create diatom blooms, krill, and whales: ALL depleted elements need to be added in proper ratios for balanced results and effective development of Marine CDR.

Volcanic Ash has more than just Iron, it contains many other trace metals and micro-nutrients. So the natural fertilization is NOT IRON Fertilization, it is Micro-Nutrient Fertilization.

Bravo, Peter!
My comment inspired by TED’s caveat in the description
TED, please cite sources to support your statement: "Ocean iron fertilization remains criticized by experts working in this field who have expressed concerns about its environmental impacts." I understand this not to be true. I challenge you to prove me wrong.
I hope this triggers an avalanche and that TED either retracts or backs up its claim.

My TEDx talk on climate restoration and OIF just came out!
It's a great short explainer for your friends about why we are working on CDR and OIF.
Please view it, like it, comment on it, and share it with your communities and friends.
It is designed to tell funders why we're doing OIF--and why they may want to fund it. OIF is the only CDR method that has been shown to meaningfully reduce CO2 levels (before ice ages).
It refers to my paper in review now: The Pinatubo CO2 pause suggests a rapidly testable path to multi-Gt mCDR (preprint) If you haven't seen it--read it!

Researchers in India appear to be leading in this field, and need to take the lead!
Apparently pilot experiments related to Sev Clarke’s Buoyant Flake concept are underway near the National Institute of Oceanography (NIO) in Goa, India.
The Arabian Sea, off Western India, has episodic upwelling and hypoxic zones. I don’t know more about the work being done at NIO, but my colleague Ishfaq Mir, India’s expert on trace elements in rocks, soils, and sediments, did his PhD thesis on trace element sources in the sediments and knows the groups involved.
He has shown that balancing trace element nutrition in India’s soils with rock powders and biochar could allow India to feed itself and sequester carbon, and the same attention needs to be paid to the ocean productivity around India!
