Graph of the Day: Ocean Heat Content Anomaly, 1955-2007
XBT corrected estimates of annual ocean heat content anomaly (1022 J) for the 0–700 m layer. Differences among the time series arise from: input data; quality control procedure; gridding and infilling methodology (what assumptions are made in areas of missing data); bias correction methodology; and choice of reference climatology. Anomalies are computed relative to the 1955–2002 average. Figure reproduced from Palmer et al. (2010).
