I have a question.... do these carbon sinks ever get "full"? Then what happens?

[CHyLmxDr]

They could reach equilibrium with the atmosphere, at which point they effectively stop taking in carbon. Or depending on the wildlife it could be turned into limestone via animal and microbe shells.

Carbon sinks. To reiterate the three mentioned

• Wind-driven circulation
• Eddies of order 100 km across
• Sinking or organisms

I agree that these are the main three.

Full is when the carbon at depth matches that at the surface. So if the atmospheric CO2 rises then more carbon is taken down to the depths. So with a rising atmospheric CO2 the carbon sinks can never get full.
