Heat content and steric height anomalies illustrate ocean changes observed by Argo network.. The horizontal distribution of the changes is estimated by comparing the 2004-2012 ISAS13 average to long term estimates. Time series of the volume average over the period is another index to monitor the state of the ocean.
Global Ocean Heat Content Anomaly (0-2000m)
Global Ocean Heat Content (OHC) time series at 100, 500, 700, 1500, 2000 m are monitored from ISAS interpolated temperature profiles.
