Web Figure 1a. Time series for 1948-98 of ocean heat content (1022 J) in the upper 300 m for the Atlantic Ocean. Note that 1.5 1022 J equals 1 watt-year-m-2 (averaged over the entire surface of the earth). Vertical lines though each yearly estimate represent plus and minus one standard error of the estimate of heat content.
Web Figure 1b. Time series for 1948-98 of ocean heat content (1022 J) in the upper 300 m for the Pacific Ocean. Note that 1.5 1022 J equals 1 watt-year-m-2 (averaged over the entire surface of the earth). Vertical lines though each yearly estimate represent plus and minus one standard error of the estimate of heat content.
Web Figure 1c. Time series for 1948-98 of ocean heat content (1022 J) in the upper 300 m for the Indian Ocean. Note that 1.5 1022 J equals 1 watt-year-m-2 (averaged over the entire surface of the earth). Vertical lines though each yearly estimate represent plus and minus one standard error of the estimate of heat content.

Web Figure 2a. Time series for 1948-98 of ocean heat content (1022 J) in the upper 1000 m for the Atlantic Ocean. Note that 1.5 1022 J equals 1 watt-year-m-2 (averaged over the entire surface of the earth). Vertical lines though each five-year estimate represent plus and minus one standard error of the estimate of heat content.
Web Figure 2b. Time series for 1948-96 of ocean heat content (1022 J) in the upper 1000 m for the Pacific Ocean. Note that 1.5 1022 J equals 1 watt-year-m-2 (averaged over the entire surface of the earth). Vertical lines though each five-year estimate represent plus and minus one standard error of the estimate of heat content.
