age model based on counting of annual layers (seasonal variations of stable isotopes and ECM)

AO: added isotope interpretation, doi and chronology information

Spatial correlation between mean d18O and borehole 10-m temperatures (Lorius and Merlivat 1977)

We have determined a  gradient of 1.16 permil/A°C for this area based on a linear regression with the mean d18O and borehole 10-m temperature. (Isaksson and Karlen, Clim.Changes, 1994)

Column 'IC96ISE9-chron-NA1', with variable name 'yearEnsemble', was added to the dataset
