b.e30_alpha09b.B1850C_MTso.ne30_t233_wgx3.357

[gustavo-marques]

Purpose:
Check that applying a taper (depth = 900, power = 4) to both MLDs and BLDs used in the Bodner scheme avoids negative overturing circulation in the Nordic Seas and large oscillations in the ACC. Starting from year 183 of run 348.

Here is the taper function used:

---

Description:
Same as 355, but starting from year 183 of run 348.
