Thank you.
Quite a comprehensive report.
Unfortunately quite a few important points are missing in the Scientific
summary.
The objective of Ocean Fertilization is to grow Diatom Algae, not just any
Phytoplankton, because Diatoms sink and other plankton float on death.
The report is
It's a shame this business got mixed up with geoengineering because it
is something that should be done on it's own merits.
Humans fish the seas. As a result they remove vast amounts of
elements from the materials circulating in the ocean biosphere. We
are going to fish, and remove elements,
Approx 100MT annual catch
Approx 1 part in 10 is iron
Therefore need to replace 1000t iron pa into ocean ecosystems. But iron
isn't a limiting nutrient everywhere, so perhaps far less.
Should boats be tipping NPK fertiliser over the side, too? Far larger
volumes are required.

You calculation is way of the mark.
Iron does not cause growth of Fish directly, it only causes growth of
phytoplankton.
These are consumed by zooplankton and small fish and these by bigger fish.
The Phytoplankton to Fish ratio for the large fish that people prefer to
eat is about
