Primary Comparisons:
 Five model simulations compared to Levitus
 climatology
 HYCOM KPP
 HYCOM KPP (theta-S)
 HYCOM K-T Implicit
 HYCOM K-T MICOM Mode
 HYCOM K-T Explicit
 The primary comparisons evaluate the primary vertical
 mixing schemes plus the consequences of
 selecting theta-S advection (where T is not conserved) instead of T-S advection
 
 Other Comparisons:
 HYCOM K-T MICOM mode vs. MICOM 2.8
 Demonstrates expected strong similarity between the
 models
 HYCOM K-T 1 vs. HYCOM K-T 2
 Compare performance of the two hybrid K-T mixed layer
 models
 HYCOM KPP (Rlx. BC) vs. Levitus Climatology
 Compare most realistic simulation to observations
