Snow thickness measurements at ice station PS124_20210515_4 during RV POLARSTERN cruise PS124

Snow depth measurements were obtained using a MagnaProbe (Snow-Hydro, Fairbanks, Alaska, USA) during walking surveys on most ice stations during PS124. The walks were randomly done on the entire floe. The MagnaProbe measurements were accompanied by measurements of the total sea-ice thickness with a ground-based multifrequency electromagnetic induction instrument (GEM-2) along the same transect.在PS124航次的多数冰站徒步考察过程中，采用MagnaProbe（Snow-Hydro公司，美国阿拉斯加州费尔班克斯市）获取雪深测量数据。本次徒步考察在整片浮冰区域随机进行。MagnaProbe雪深测量同步沿同一测线，使用地基多频电磁感应仪（GEM-2）完成海冰总厚度的测量工作。
