ENV4980702: European Project for Ice Coring in Antarctica (URI: https://cordis.europa.eu/project/id/ENV4980702) Comment: Stack consists of 16 individual records. For the individual records of the accumulation rates see Oerter et al., (2000). To calculate composite records, the individual records were normalised (my=0 , Var=1) and stacked. Stack was multiplied by mean of standard deviations of the individual records and the regional mean is added.
