From: Abyssal ocean overturning shaped by seafloor distribution

Δ14C mapped (a) and measured (b) on the 28.045 kg m−3 neutral density surface. Dark grey patches in a are portions of the density surface that are unmapped owing to insufficient data density. Similar maps have been constructed for 140 density surfaces spanning the world ocean’s neutral density range13.
