Ocean Macroalgal Afforestation (OMA) of 9% of the ocean surface also needs an albedo study. Perhaps start with the Sargasso Sea as an example of an existing floating macroalgal (seaweed) forest.
There should be a difference in albedo changing from the typical "nutrient desert" to the high primary productivity of a seaweed forest sustained by quick nutrient recycling. Whatever that change is can be compensated by tweaking how the seaweed forests are managed.

HiThere was a lot of coverage of the Haida salmon / Russ George ocean iron fertilization experiment, both on this list and in the wider media. I guess a lot more data has been made available over time from satellites, etc.However, I don't recall seeing anything which quantified the ocean colour change and the resulting effect on albedo. I've previously run some numbers which suggested a globally significant effect from widespread ocean albedo changes resulting from biological interventions. Sadly, I've been unable to calibrate these estimates due to a lack of ability to convert photographic brightness to absolute albedo.I'm turning to the list for help, to see if anyone can offer data or calculations. Do you know, or can you infer, the change in absorption / reflection resulting from OIF? The Haida experiment is an ideal source, but any help is welcomed.ThanksA--
