•The following three
 slides illustrate layer thickness and total heat content evolution during the 25-year spinups of six of the HYCOM
 simulations.
 –Results are similar
 for all six cases.
 –Model adjustments in
 the upper ocean have been largely completed after the 25-year spinup
 –Significant
 adjustments of intermediate and deep water are still occurring after 25 years. These large adjustments occur in part
 because the p(lat) initialization was not
 accurate at these depths.
 •The subsequent four
 slides present the volumetric T-S censuses.
