Short description of the statistical fields in WOA09
 Objectively analyzed climatologies are the objectively interpolated mean fields for an oceanographic variable at standard depth levels for the World Ocean.
 The number of observations of each variable in each onedegree and fivedegree square of the World Ocean at each standard depth level.
 The statistical mean is the average of all unflagged interpolated values at each standard depth level for each variable in each onedegree
and fivedegree square which contain at least one measurement for the given oceanographic variable.
 The standard deviation about the statistical mean of each variable in each onedegree and fivedegree square at each standard depth level.
 The standard error of the mean of each variable in each onedegree and fivedegree square at each standard depth level.
 The seasonal or monthly climatology minus the annual climatology at each onedegree square at each standard depth.
 The statistical mean minus the climatological mean at each onedegree square at each standard depth. This value is used as an estimate of interpolation and smoothing error.
 The number of onedegree squares within the smallest radius of influence around each onedegree square which contain a statistical mean.
