Abstract:
Discrete samples (22mm depth-resolution) for snow-cores KF13, KF14, KF15, KF16, KF17, KF18, and KF20, analyzed in 2015 at the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar-und Meeresforschung, in Potsdam, Germany. All cores were sampled along the trench T15-1 in 2014/15, correspond to depths 240-340cm and are 5 meters spaced (relative distance to the starting coordinate). Isotopic measurements were realized by CRDS (Cavity-Ring-Down Spectroscopy, L-2130-i, Picarro Inc.).
