中国第21次南极科学考察(2004-2005)中山站海面雪密度测量数据

中国第21次南极考察期间，对雪的密度的测量是在中山站及其周边海冰面上积聚了一定厚度的雪且能够切割成块的情况下进行的。由于当年度总体降雪较少，且海冰面上积雪少，故海面雪密度测量只在5月、6月、9月这三个月中进行了测量。测量时从纳拉湾海冰面上取一定体积的雪块用干净器皿带回实验室，从上到下分层切成小块进行质量和体积的测量，然后计算出其密度。本数据为中国第21次南极科学考察中山站海面雪密度测量数据，数据内容包含采样日期、位置、样品长宽高、重量、体积、密度、相对密度等信息。

During China's 21st Antarctic Scientific Expedition, snow density measurements were conducted under conditions where snow had accumulated to a certain thickness on the sea ice surrounding Zhongshan Station and could be cut into blocks. As the overall snowfall was low that year and there was limited snow cover on the sea ice, snow density measurements over the sea ice were only carried out in May, June and September. During measurements, snow blocks of a certain volume were collected from the sea ice in Narra Bay, brought back to the laboratory in clean containers, cut into small pieces layer by layer from top to bottom for mass and volume measurements, and then their density was calculated. This dataset contains snow density measurement data over the sea ice near Zhongshan Station from China's 21st Antarctic Scientific Expedition, including sampling date, location, length, width, height of the samples, mass, volume, density and relative density, etc.
