The iron dumping was shown to be quickly removed from the seawater through its incorporation into some component of the algae that then sank: much like nitrogen. I think the iron might have been incorporated into a shell of some sort as part of the algae--possibly mixed in with CaCO3 or something. That was the reason Iron dumping was abandoned: it was hoped the iron would remain in the ocean ecosystem for longer.

@shigeta The goal is to remove nitrogen from the river water, since in the open ocean nitrogen is the limiting reagent for algal growth.

@shigeta If the algae continue to grow and consume oxygen, they they are also consuming nutrients that would otherwise contribute to algal blooms and/or dead zones. The idea is essentially to exhaust the runoff nitrogen through speeding algae growth - not necessarily to instantaneously solve the problem of dead zones. This should reduce the extent of dead zones.

Phycology would seem to be an ideal place to study mechanisms of phosphate absorption at varying pH.

comment Good source that explains the evolution of single-celled organisms “from scratch”
@C.LawrenceWenham Did it fit the bill?
