(Table 2) Ice, snow and freeboard statistics from measurement transects at 11 ice stations during Aurora Australis cruise SIPEX in 2007

The Sea Ice Physics and Ecosystem experiment (SIPEX) was conducted in the East Antarctic pack ice zone between 115-130°E from 9 September - 11 October, 2007. In situ measurements of sea-ice and snow properties were conducted at 15 ice stations, together with ship-based ASPeCt observations. The ice and snow thickness varied considerably in different regions of the pack ice, with particularly thick ice associated with deformation and a strong slope jet in the southwest of the study region. The mean ice thickness was 0.99 m (1.57 m excluding the northern marginal ice zones), but varied from 0.61 m along the southern leg to 1.80 m along the western leg, with pockets of considerably thicker ice in some regions. Swell was observed on two occasions penetrating more than 330 km south of the ice edge into regions with 80-100% ice concentration. Ice thicknesses calculated from near coincident ICESat laser altimetry (1.74 m) are similar to the in-situ observations in the central pack (1.57 m).海冰物理与生态实验（Sea Ice Physics and Ecosystem experiment, SIPEX）于2007年9月9日至10月11日期间，在东经115°至130°之间的东南极浮冰区开展。研究团队在15个冰站开展了海冰与积雪属性的原位测量，并同步开展了船载ASPeCt观测。 研究区内不同浮冰区域的冰、雪厚度差异显著，其中研究区西南部因海冰变形与强斜坡急流作用，海冰厚度尤其可观。海冰平均厚度为0.99米（剔除北部边缘冰区后为1.57米），整体厚度范围从南部航段的0.61米至西部航段的1.80米不等，部分区域还存在局部厚冰区。 研究团队两次观测到涌浪穿透冰缘向南延伸超过330公里，进入冰浓度达80%-100%的区域。通过近乎同步的ICESat激光测高数据计算得到的海冰厚度（1.74米），与中心浮冰区的原位观测结果（1.57米）较为吻合。
