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亚站（Svea Station）与瓦萨站（Wasa Station）附近沿考察航线开展的地面无线电回声测深实验所获取的冰厚数据。该数据来源于日瑞联合JASE考察航线项目，由日本国立极地研究所（National Institute of Polar Research, NIPR，依托第48、49次日本南极考察队（JARE48与JARE49））与斯德哥尔摩大学（Stockholm University）共同完成采集。本联合考察项目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·霍姆隆德（Per Holmlund）。实验采用脉冲调制甚高频（Very High Frequency, VHF）雷达测深系统，其峰值发射功率为1 kW，中心频率为179 MHz，发射脉冲宽度为250 ns。测点位置通过全球定位系统（Global Positioning System, GPS）记录，定位误差不超过20 m。本数据的原始发表文献为藤田等人2011年与2012年的两篇研究论文（Fujita et al., 2011; Fujita et al., 2012）。2021年，研究人员对本数据集进行了验证与校正（Tsutaki et al., 2022，《TC》期刊论文）。
