Introduction
This is a collection of fourteen figures and a table that are cited and discussed in the main text of this paper.
1. 2008gl037155-fs01.jpg
Frequency distribution of 2-degree latitude x 4-degree longitude boxes XBT minus OSD/CTD temperature differences (degree C) for 1999 at 150 m depth.
2. 2008gl037155-fs02.jpg
Time series of the number of 2-degree latitude x 4-degree longitude boxes per year of the MBT minus OSD/CTD difference pairs and a similar series for XBT minus OSD/CTD difference pairs.
3. 2008gl037155-fs03.jpg
Percent ocean area of 2-degree latitude belts with 2-degree latitude x 4-degree longitude boxes containing XBT minus OSD/CTD differences.
4. 2008gl037155-fs04.jpg
(a) Time series of the offsets based on arithmetic mean of the offsets (degree C) between XBT and OSD/CTD data from Gouretski and Koltermann [2007]. (b) Time series of the offsets based on median of the offsets (degree C) between XBT and OSD/CTD data for this study. Calculations are based on at least 30 overlapping 2-degree latitude x 4-degree longitude boxes per year and level. Red indicates positive value, blue indicates negative values.
5. 2008gl037155-fs05.jpg
(a) Time series of offsets based on arithmetic mean of the offsets (degree C) between MBT and OSD/CTD data from Gouretski and Koltermann [2007]. (b) Time series of offsets based on the median of the offsets (degree C) between MBT and OSD/CTD for this study. Calculations are based on at least 30 overlapping 2-degree latitude x 4-degree longitude boxes per year and level. Red indicates positive value, blue indicates negative values.
6. 2008gl037155-fs06.jpg
Time series (5-year running means) of the temperature corrections based on medians of the differences (degree C) applied to MBT observations. Calculations are based on at least 30 overlapping 2-degree latitude x 4-degree longitude boxes per year and level.
7. 2008gl037155-fs07.jpg
Time series of the offsets (degree C) between XBT and OSD/CTD based on the median of the offsets after bias corrections have been applied twice. Calculations are based on at least 30 overlapping 2-degree latitude x 4-degree longitude boxes per year and level. Red indicates positive value, blue indicates negative values.
8. 2008gl037155-fs08.jpg
Time series of the offsets (degree C) between MBT and OSD/CTD after bias corrections have been applied twice based on the median of the offsets. Calculations are based on at least 30 overlapping 2-degree latitude x 4-degree longitude boxes per year and level. Red indicates positive value, blue indicates negative values.

Yearly time series of ocean heat content (10E+22 J) for the 0-700 m layer from this study and from Domingues et al. [2008] and Ishii and Kimoto [2008]. Linear trends for each series for 1969-2003 given in the upper left portion of the figure. Reference period is 1957-1990.
10. 2008gl037155-fs10.jpg
Yearly time series of ocean heat content (10E+22 J) for the 0-700 m layer from Domingues et al. [2008] and based on application of the Wijffels et al. [2008] XBT bias correction to our profile database. Reference period is 1957-1990.
11. 2008gl037155-fs11.jpg
Time series (1955-2008) of yearly ocean heat content (10E+22J) for the 0-700 m layer of the world ocean and individual ocean basins. The linear trend is shown in each panel for 1969-2008. The percentage in the upper left of each panel each panel is the percent variance accounted for by the linear trend. The vertical lines centered on each yearly estimate represent +/- 2*S.E. determined from the four individual seasonal estimates of heat content for each year plotted. Reference period is 1955-2006.
12. 2008gl037155-fs12.jpg
Seasonal time series of yearly ocean heat content (10E+22 J) for the 0-700 m from this study and their trends for 1969-2008. Reference period is 1955-2006.
13. 2008gl037155-fs13.jpg
Yearly time series of ocean heat content (10E+22 J) for the 0-700 m layer based on the all-data yearly fields and the average of the four seasonal yearly fields. Plotted about the average of the four seasonal yearly series is +/- 2*S.E. of the mean for each year based on the four seasonal values.
14. 2008gl037155-fs14.jpg
Time series of seasonal OHC700 (10E+22 J) estimates and annual mean of the four seasons.
