Snow density measured in snow pits using the snow fork during the drift station (2004-11-29 to 2005-01-02) of the POLARSTERN cruise ANT-XXII/2 (ISPOL)

Various physical properties of snow and sea ice were measured during ice stations in the Western Weddell Sea, Antarctic, during the POLARSTERN cruise ANT-XXII/2 (ISPOL) in 2004. All stations during the transect from the ice edge to the drift station were reached by helicopter. During the drift station (2004-11-29 to 2005-01-02) the ice was accessed through a gangway directly from the vessel. During the drift station, patches P6 and P9 were on first-year sea ice, patches P5 and P8 on multi-year sea ice. All vertical positions are corrected to freeboard, e.g. z=0 represents the snow-ice interface. More detailed information about the data sets and methods are available from the cruise report (section 3.2). Core names (labels) refer to the name convention of that cruise, including date and core type.2004年，在南极威德尔海西部开展的POLARSTERN航次ANT-XXII/2（ISPOL）期间，科研人员在多个冰站完成了积雪与海冰多项物理特性的测定工作。所有分布在从冰缘至漂移冰站样带上的观测站位，均通过直升机抵达。在2004年11月29日至2005年1月2日的漂移冰站作业阶段，科考人员可通过舷梯直接从母船登冰开展观测。本次漂移冰站作业期间，样区P6与P9覆盖当年生海冰（first-year sea ice），样区P5与P8覆盖多年海冰（multi-year sea ice）。所有垂直位置均已校正至干舷（freeboard）高度，例如z=0代表雪-冰界面。有关本数据集与观测方法的详细信息，可查阅该航次报告的3.2章节。岩心样本的命名（标签）遵循本次航次的命名规范，涵盖采集日期与岩心类型。
