Each kilogram of iron can fix 83000 kg of carbon dioxide and turn it into biomass.
- im3w1l 7y agoHow much of that is permanently fixed, and how much of it goes right back when those organisms die?
- namibj 7y agoBury it deep? A large part of the carbon should remain and turn into coal.
- azernik 7y agoFrom linked article: "Of the carbon-rich biomass generated by plankton blooms, half (or more) is generally consumed by grazing organisms (zooplankton, krill, small fish, etc.) but 20 to 30% sinks below 200 meters (660 ft) into the colder water strata below the thermocline. Much of this fixed carbon continues into the abyss, but a substantial percentage is redissolved and remineralized. At this depth, however, this carbon is now suspended in deep currents and effectively isolated from the atmosphere for centuries. (The surface to benthic cycling time for the ocean is approximately 4,000 years.)"
