A major feature of Figure 5.1 is the relatively large increase
in global ocean heat content during 1969 to 1980 and a sharp decrease during 1980 to 1983.
Change in
global ocean heat content between the surface and 2000 meters of depth from 1958 to 2017 (top) and distribution of ocean heat content anomalies in 2017 (bottom).
The abstract suggests that the tropical Pacific and Atlantic Oceans are responsible for 65 % of warming
of global ocean heat content for the depths of 0 - 700 meters since 2000.
The estimate of increase in
global ocean heat content for 1971 — 2010 quantified in Box 3.1 corresponds to an increase in mean net heat flux from the atmosphere to the ocean of 0.55 W m — 2.
With GRACE retrievals of surface mass commencing in 2002 and ARGO - derived estimates of
global ocean heat content beginning a few years later, an era of unprecedented diagnostic capabilities began.
The estimated increase of
observed global ocean heat content (over the depth range from 0 to 3000 meters) between the 1950s and 1990s is at least one order of magnitude larger than the increase in heat content of any other component.
In the following paper, Trenberth and collaborators argue that the «missing» heat is sequestered in the ocean, below 700 m: Ref: «Distinctive climate signals in reanalysis
of global ocean heat content» (Geophysical research letters — first published 10 May 2013)
However, the large - scale nature of heat content variability, the similarity of the Levitus et al. (2005a) and the Ishii et al. (2006) analyses and new results showing a decrease in the global heat content in a period with much better data coverage (Lyman et al., 2006), gives confidence that there is substantial inter-decadal variability
in global ocean heat content.

global ocean heat content, Environmetrics, 2012.
Bayesian estimation of climate sensitivity based on a simple climate model fitted to observations of hemispheric temperatures and global ocean heat content
But if you google «noaa ocean heat and salt content» and compare the first two graphs («0 - 700m
global ocean heat content» versus «0 - 2000m global ocean heat content») you will see that the sea SURFACE temperature is much more reflective of what is going on in the atmosphere than the oceans depths.

The study says
the global ocean heat content record robustly represents the signature of global warming, and is affected less by weather - related «noise» and climate variability such as El Niño and La Niña events.
Here we present the time evolution of
the global ocean heat content for 1958 through 2009 from a new observational - based reanalysis of the ocean.
More vindication for Dr. Roger Pielke Sr. who has said that
global ocean heat content is the best metric for tracking global warming.
New analyses indicate that
global ocean heat content has increased significantly since the late 1950s.
Bayesian estimation of climate sensitivity based on a simple climate model fitted to observations of hemispheric temperature and
global ocean heat content.
