100km-scale isotopic (δ18O, δD) variability of the top-meter between B31 and Kohnen, Droning Maud Land

Isotopic composition of the top-meter of the snowpack along a 115km traverse between B31 and D48, near Kohnen station, Droning-Maud Land, East-Antarctica. The upper 100cm snow was sampled with the dual-tube sampling technique (Dallmayr et al., 2020), or by mixed subsections of the top-120cm of 90m l...

Description
Summary:Isotopic composition of the top-meter of the snowpack along a 115km traverse between B31 and D48, near Kohnen station, Droning-Maud Land, East-Antarctica. The upper 100cm snow was sampled with the dual-tube sampling technique (Dallmayr et al., 2020), or by mixed subsections of the top-120cm of 90m long trenches excavated by piston-bully. The isotopic analysis were realized by CRDS (Cavity-Ring-Down Spectroscopy, l2130-i, Picarro Inc.) at the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar-und Meeresforschung, in Bremerhaven and in Potsdam, Germany.
