Ice thickness near Svea Station and Wasa 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 the traverse route near Svea Station and Wasa 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).本数据集收录了南极东部斯维雅站（Svea Station）与瓦萨站（Wasa Station）附近沿线考察航线上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（NIPR）所辖第48、49次日本南极科考队（JARE48与JARE49）与斯德哥尔摩大学（Stockholm University）联合开展的日瑞JASE考察航线调查采集完成。本次联合调查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）。本次调查采用峰值发射功率1 kW、中心频率179 MHz、发射脉冲宽度250 ns的脉冲调制甚高频（VHF）雷达测深仪。所有测点的位置均通过全球定位系统（GPS）记录，定位误差不超过20米。该数据的原始研究论文为藤田等（2011）与藤田等（2012）的两篇成果。2021年，研究人员对该数据进行了验证与修正（Tsutaki et al. 2022，TC论文）。
