This is a rewilding article, but it's about rewilding the Southern Ocean by adding iron to restore krill populations to in turn restore whale populations.

I remember a few years back we had an PM about seeding the Southern oceans with iron as an attempt to capture carbon.  We talked a lot about unintended consequences as humans trying to out think nature.  I still think it is an idea worth pursuing.
