Description
The data set provided here comprises time series of oceanic heat content, sea level change and time series of temperature and salinity anomalies. The basis for this are in-situ measurements from the World Ocean Database 2013 (Boyer et al., 2013) and additional data, that had been processed through the end of 2016. The temperature and salinity anomalies are departures of the measurements of the two parameters from climatological mean values of the World Ocean Atlas 2009 (Locarnini et al., 2010). Based on these anomalies, the oceanic heat content and the sea level change are estimated.
By adding the mean climatological values of the World Ocean Atlas 2009 to the respective anomalies, a time series of global fields of water temperature and salinity can be constructed.
