Purpose:

Remove MLE_TAPER with BBL_EFFIC = 0.2 to determine whether the AMOC reversal in the Nordic Seas results from reduced overflow entrainment (BBL_EFFIC = 0.01) and the associated MLE-driven overturning.

---

Description:

Same as 363 but without SrcMods with MLE taper.
Starting from case 360 at year 93.
