"The deep ocean has continued to warm, while the upper 300m OHC appears to have stabilized. The differences in recent trends among the different ocean layers are profound. The small warming in the upper 300m is belied by the continuing warming for the ocean as a whole, with considerable warming occurring below 700m. "
"In an observing system experiment where Argo is withdrawn, the ocean heating for the last decade is reduced (0.82± 0.10 W m^-2), but is still significantly higher than in previous decades. The estimation shows depths below 700m becoming much more strongly involved in the heat uptake after 1998, and subsequently accounting for about 30% of the ocean warming"
