I've thought about doing a kickstarter to charter a boat to try this (kind of a Bizzaro world version of the <i>Rainbow Warrior</i>.) but was told by some experts (took their class) not to do this.<p>The #1 concern is that this is borrowing from Peter to pay Paul, that is you end up depleting nutrients other than iron so that there is less production somewhere else.<p>A #2 issue is that it's not as simple as it sounds, you can't just dump iron off the size of a barge and expect it to work, you really need to be monitoring the process and need a whole flotilla to do that.
What a coincidence that in the CarbonDioxideRemoval google group I opened that can of worms just the day before that guest essay opened it in "The Newspaper of Record".<p><a href="https://groups.google.com/g/CarbonDioxideRemoval/c/gslzzNXya8s/m/mt1FanDKBAAJ" rel="nofollow noreferrer">https://groups.google.com/g/CarbonDioxideRemoval/c/gslzzNXya...</a><p>Every time this has been brought up since the 1990s, it has driven scientists over the edge. As I pointed out to the CDR group, this is just one more case where the Algorithmic Information Criterion is ignored as a resolution to scientific controversies (rendered intractable more because of their very importance than the lack of data).
