南极阿德雷岛湖泊沉积210Pb、137Cs定年及其环境意义
210pb, 137Cs Dating of Lake Sediments from Ardley Island(Maritime Antarctic) and Their Environmental Implications
摘要
Abstract
The activity of 210Pb and 137Cs of lake sediments, namely Y2 and G, respectively from Ardley Island,Antarctica have been measured. According to the profiles of 210Pb and 137Cs activity, we used CRS model to date the G lake, which spans about 134 ± 43 years. Base on the dating, we estimate the velocity of deposition. The increased sedimentation rates and the inventories of 210Pb and 137Cs as well as their flux being higher than the atmospheric deposition could be reasonably attributed to the supply of a great amount of ice-melt water.关键词
