Ice thickness along the traverse line across the major route at longitude +5 degree near Kohnen, 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 line near the Kohnen 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).

该数据集包含东南极洲科嫩站附近沿测线开展的地面无线电回波探测实验所记录的冰厚数据。这些数据由日本国立极地研究所（NIPR，第48和49次日本南极考察队（JARE48与JARE49））与斯德哥尔摩大学联合开展的日瑞JASE traverse考察中采集。联合调查的项目负责人（PI）为藤田修二（日本NIPR）与佩尔·霍尔姆伦德（瑞典斯德哥尔摩大学）。他们使用了脉冲调制甚高频（VHF）雷达测深仪，其峰值发射功率为1千瓦，中心频率179兆赫兹，发射脉冲宽度250纳秒。测点位置通过全球定位系统（GPS）记录，误差在20米以内。该数据的原始文献为Fujita等人（2011）及Fujita等人（2012）。2021年，数据经过验证与校正（Tsutaki等人，2022，TC论文）。
