the most comprehensive study of changes in ocean heat content to date by quite some margin.
has allowed the group to rule out that the changes are related to natural variability in the climate system.
The infilling method of DOM employs statistics of observed ocean variability estimated from altimeter data. We compare the spatially complete infilled estimates (1TIF) with subsampled 1T data (1TSS) restricted to available in situ measurements (see Methods). Not surprisingly, the 1TSS variability in Fig. 1b is greater than that of 1TIF, particularly at the times/locations of the sparsest sampling (early in the record and in the southern oceans; Supplementary Fig. S1).\
