Theory 42/Millennia/Ocean chemistry
Carbonate Compensation Is Mixing Against Dissolution
The claim
The depth at which carbonate dissolves is set by the ratio of ocean mixing time to dissolution rate, so slow mixing pushes the horizon deeper.
01Mechanism
Dissolution neutralises added carbon; the ratio determines how fast the ocean can redistribute alkalinity.
02Prediction
Horizon depth should track the ratio.
03Refutation
Depth tracking temperature would remove mixing.
