Ice thickness along the traverse routes between Kohnen and Svea Station, Antarctica, based on JASE ground-based radar surveys

This dataset contains the ice thickness data recorded by ground-based radio echo sounding experiment carried out along a traverse route from the Kohnen Station toward Svea Station in East Antarctica. The data were recorded in the joint Japanese-Swedish JASE traverse survey by NIPR (the 48th and 49th Japanese Antarctic Research Expedition (JARE48 and JARE49)) and Stockholm University. PIs of the joint survey are Shuji Fujita (NIPR, Japan) and Per Holmlund (Stockholm University, Sweden). They used a pulse-modulated VHF radar sounder with a peak transmission power of 1 kW, a center frequency of 179 MHz and a transmitter pulse width of 250 ns. Position of sites are recorded based on GPS with errors within 20 m. Fujita et al. (2011) and Fujita et al. (2012) are the original papers for the data. In 2021, the data were validated and corrected (Tsutaki et al. 2022, TC paper).

本数据集收录了沿南极东部科嫩站（Kohnen Station）至斯韦亚站（Svea Station）横断考察路线开展的地面无线电回声测深实验所获取的冰厚数据。该数据由日本国立极地研究所（National Institute of Polar Research，简称NIPR）联合斯德哥尔摩大学，依托第48、49次日本南极考察队（JARE48、JARE49）执行的日瑞联合JASE横断考察项目采集。本次联合考察的首席研究员为日本国立极地研究所的藤田修司（Shuji Fujita）与瑞典斯德哥尔摩大学的佩尔·霍尔蒙德（Per Holmlund）。实验所用设备为脉冲调制甚高频（Very High Frequency，VHF）雷达测深系统，其峰值发射功率为1 kW，中心频率179 MHz，发射脉冲宽度250 ns。测点位置通过全球定位系统（Global Positioning System，GPS）测定，定位误差不超过20 m。该数据的原始研究文献为Fujita等人（2011）与Fujita等人（2012）发表的论文。2021年，相关数据经过校验与修正（Tsutaki等，2022，TC期刊论文）。
