Introduction
This data set contains figures referred in the main text and tabular
values of change in ocean heat content and thermostatic component of sea
level change. Appendix provides a summary of objective analysis (OA) and
how the standard errors were estimated.

1.1 Figure S1. Time series of ocean heat content (1022J) for the 0-2000 m
layer for the major ocean basins based on running pentadal analyses. Each
pentadal estimate is plotted at the midpoint of the 5-year period. The
vertical bars represent 2.+ACo-S.E. about the pentadal estimate. The linear
trend line and the percent variance accounted for by the linear trend are
shown in red on each panel. Reference period is 1955-2006.
1.2 Figure S2. Time series for the major ocean basins of ocean heat
content (1022J) for the 0-700 m layer based on running pentadal analyses.
Each pentadal estimate is plotted at the midpoint of the 5-year period.
The vertical bars represent 2.+ACo-S.E. about the pentadal estimate. The
linear trend line and the percent variance accounted for by the linear
trend are shown in red on each panel. Reference period is 1955-2006.
