Electromagnetic measurement of sea ice thickness on ice stations during the SIPEX II voyage of the Aurora Australis, 2012

We observed total thickness (snow thickness + ice thickness) of sea-ice floes along 100m transects using an electromagnetic (EM) sensor.

The data were read from the EM and written by hand into a log book as we moved along the transect. They were then transferred into an Excel spreadsheet.

The parameters included are:
- distance along transect
- conductivity (vertical)
- conductivity (horizontal)
- total thickness (derived from vertical and horizontal conductivities)

本研究使用电磁（electromagnetic, EM）传感器，沿100米测线对海冰浮冰的总厚度（积雪厚度+海冰厚度）开展观测。
观测过程中，我们沿测线行进时读取电磁传感器数据，并手动将其记录至日志簿中，后续将数据导入Excel电子表格进行整理。
本次数据集包含以下参数：
- 测线方向距离
- 垂直方向电导率
- 水平方向电导率
- 总厚度（由垂直与水平电导率推导得到）
