Abstract:

TALDICE deep1 ice core chronology (years) for the TALDICE ice core for ice and gas matrix between 1438 m depth and 1548 m depth at 1 m resolution. The chronology is correlated with accumulation rate, thinning function and LIDIE (lock-in-depth in ice equivalent).

The TALDICE deep1 chronology is defined for both gas and ice matrix between 1438 m depth and 1548 m depth with the application of the IceChrono1 model (Parrenin et al. 2015). The age scale is defined at 1 m resolution and gas and ice age ages (expressed in years) with their respective uncertainties. The chronology is correlated with accumulation rate, thinning function and LIDIE (lock-in-depth in ice equivalent).
