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.
