中国第25次南极科学考察航线数据(2008-2009年)

中国第25次南极考察于2008年10月20日乘“雪龙”号从上海启航，2009年4月9日结束考察返回上海。本次考察在南极内陆冰盖的最高点冰穹A地区，建立了我国第一个南极内陆考察站昆仑站，在南极冰穹A地区进行了雪冰采样、天文观测、基础测绘考察，完成了南极下坡风结构现场观测试验。 本数据包括航迹数据（excel和csv格式）和航线数据（线状和点状），共14个文件，总大小为3.41MB。时间范围:2008-10-20 至 2009-04-10;空间范围:西: 76.1168, 东: 126.6008, 北: 33.2300, 南: -69.0065The 25th Chinese National Antarctic Research Expedition departed Shanghai aboard the icebreaker Xuelong on October 20, 2008, and concluded its fieldwork and returned to Shanghai on April 9, 2009. During this expedition, China's first inland Antarctic research station, Kunlun Station, was established at Dome A—the highest point of the Antarctic inland ice sheet. Field activities conducted in the Dome A region included snow and ice sampling, astronomical observations, and basic surveying and mapping, as well as in-situ observation experiments on the structure of Antarctic downslope winds. This dataset comprises track data (available in Excel and CSV formats) and route data (in line and point geometries), with a total of 14 files and a combined size of 3.41 MB. The temporal coverage of the dataset ranges from October 20, 2008, to April 10, 2009. The spatial coverage is specified as: West: 76.1168, East: 126.6008, North: 33.2300, South: -69.0065.
