Fig. 6: Mean σ-z diagram of AMOC transport (Sv) across OSNAP West and OSNAP East.

From: Horizontal circulation across density surfaces contributes substantially to the long-term mean northern Atlantic Meridional Overturning Circulation

a, d OSNAP observations (OBS). b, e Robust diagnostic calculation (RDC). c, f Control simulation (MODEL). a–c OSNAP West subsection. d–f OSNAP East subsection. The color shaded σ-z diagram in each panel shows the integrated volume transport (Sv) across each subsection over each potential density (σ0) bin (x-axis) and depth (z) bin (y-axis); the integrated transport across each subsection over each potential density bin summed over the entire depth range is shown in the blue curve above; the integrated transport across each subsection at each depth bin summed over the entire potential density range is shown in the blue curve on the left. The accumulated AMOC transport in density- and depth- space corresponds to AMOC streamfunctions across each subsection (Fig. 3a, b, d, e).
