Document Summary
The partially submersed mass is less dense than the fluid it"s submersed in. This is because the net buoyancy force due to the surrounding fluid will be upward, opposing the downward gravitational force, if the partially submersed mass is less dense than the fluid it"s submersed in. If the submersed mass" density is the same as the fluid it"s submersed in, then it would be stable and fully submersed due to the gravitational force equally balancing the buoyancy force. Martin hypothesized that adding iron to the ocean in these regions would trigger massive phytoplankton blooms. (2 pts) if the phytoplankton bloom ultimately resulted in the export of organic carbon to the deep ocean or sediments, it would remove. Co2 from the atmosphere over long time scales. (2 pts) the removal of. Co2 from the atmosphere would decrease the greenhouse effect due to the gas, decreasing global temperatures. Martin hyperbolized that we could therefore trigger an ice age. )
