南极普里兹湾表层沉积物中元素含量统计学特征数据集

Element Concentration and Statistical Feature Dataset of Surface Sediments in Prydz Bay, Antarctica

中国南极科学考察第18次(2001-2002年)至27次(2010-2011年)期间,在南极普里兹湾获得的21个表层沉积物样品,经过实验室理化分析得到地表沉积物中C、N、S、K、Ca和Ti等13种常、微量元素的含量;经统计学分析,得到南极普里兹湾表层沉积物中元素含量统计学特征数据集。该数据集包括13种元素含量的最小值、最大值、平均值、标准偏差、变异系数和相关系数。聚类结果表明,这些元素可以归为两大类:C、N和S为一类,其它元素为另一类。该数据集为普里兹湾沉积环境以及物质来源的研究提供详实信息。本数据集由1个Excel文件组成,数据量31 KB。

The Element concentration and statistical feature dataset of surface sediments in Prydz Bay,Antarctica consisted of concentrations of 13 elements,i.e.,C(OC),N(TN),S,Al,Ba,Mn,Fe,K,Ti,Rb,Zr,Ca and Sr.measured in 21 surface sediment samples collected between CHINARE18 and CHINARE 27(2001-2011)from Prydz Bay,Antarctica.The maximum,minimum,mean and standard deviations were calculated respectively,and their variation coefficients were analyzed subsequently.Statistical results showed that elements were classified in two clusters:one comprised OC,TN,and S,and another included the rest of elements.This paper introduced the data measurement method,data processing procedures,and statistical results,which is the new data input for environmental studies and source analysis of sediment in Prydz Bay.The data was archived in Excel format with the compressed data size of 31 KB.
