Discrete profiles of stable water isotopes (d18O, dD) measured in 2015 and sampled along a snow trench (T15-1) in the 2014/15 field season at Kohnen Station, Dronning Maud Land, Antarctica@en

Discrete samples (22mm depth-resolution) for snow-cores KF13, KF14, KF15, KF16, KF17, KF18, 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.).本数据集涵盖2015年于德国波茨坦阿尔弗雷德·魏格纳研究所——亥姆霍兹极地与海洋研究中心（Alfred-Wegener-Institut Helmholtz-Zentrum für Polar-und Meeresforschung）完成分析的雪芯KF13、KF14、KF15、KF16、KF17、KF18的离散样本，其深度分辨率为22毫米。所有雪芯均于2014/2015年沿T15-1探槽采集，对应深度区间为240至340厘米，采样间距为5米（相对于起始坐标的相对距离）。同位素测量采用腔环衰减光谱法（Cavity-Ring-Down Spectroscopy, CRDS）完成，所用仪器为Picarro公司（Picarro Inc.）生产的L-2130-i型设备。
