Purpose: Test the hypothesis that SST biases in the Equatorial Pacific are related to shallow boundary layer depths (BLDs) in this region. This run investigates this hypothesis by forcing a minimum BLD = 15 m everywhere.

---

Description: Twin of 078b but with MINIMUM_OBL_DEPTH = 15 m in user_nl_mom.

Unfortunately, not seeing the response we were looking for. At location of Stratus mooring MLD is a little deeper in summer as we wanted:

but SST and absorbed SW are actually a little worse:

Over the whole SE Pacific region, there may be a small decrease in +ve SST bias but generally pretty similar?
