- It distinguishes mineral weathering from hydroxide routes and flags mining emissions, trace metals, and measurement as unresolved issues.
Field notes
The page walks through mineral and hydroxide approaches, then separates the chemistry from the harder field question of how much carbon is actually removed. Its Gulf of Maine example describes alkalinity and pink dye tracked with gliders for five days, while noting no significant plankton or larval change so far. It also argues that mining, grinding, shipping, and power emissions belong in a full life-cycle assessment.
