    I've thought about doing a kickstarter to charter a boat to try this (kind of a Bizzaro world version of the Rainbow Warrior.) but was told by some experts (took their class) not to do this.

    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.

    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".

    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).
