Ice thickness in an area near an area near 75S and 10W, 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 at an area near 75S and 10W 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).本数据集收录了南极东部南纬75°、西经10°附近区域开展的地面无线电回声测深实验所获取的冰厚数据。该数据来源于日瑞联合JASE横穿科考项目，由日本国立极地研究所（National Institute of Polar Research, NIPR）组织的第48、49次日本南极研究考察队（JARE48与JARE49）与瑞典斯德哥尔摩大学共同采集。本次联合科考的项目负责人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）。本次科考采用的脉冲调制甚高频（Very High Frequency, VHF）雷达测深系统，峰值发射功率达1千瓦，中心频率为179兆赫，发射脉冲宽度为250纳秒。测点位置通过全球定位系统（Global Positioning System, GPS）获取，定位误差控制在20米以内。该数据的原始研究论文为藤田修司等人分别于2011年、2012年发表的两篇文献。2021年，该数据集经过校验与修正（Tsutaki等人，2022年，TC论文）。
