Windmill Islands lake and shallow marine sediment cores (ASAC1071; 1998/99 summer)

Cores from lakes and the shallow marine were taken for investigation of palaeoclimate through proxies such as grain size, TOC, C:N:S and diatoms. The cores have been 14-C dated with some sheel fragments having been analysed using Amino Acid geochronology. The full postglacial record, plus till and pre-glacial sediments, were recovered from two marine cores at 10.3 and 12 m depth in the sediment respectively. These cores are presently (2000) being analysed.

本研究采集湖泊与浅海沉积物岩芯，借助粒度、总有机碳（TOC, Total Organic Carbon）、碳氮硫比值（C:N:S）及硅藻等代用指标开展古气候研究。上述岩芯已通过14C测年法完成定年，部分贝壳碎片采用氨基酸地质年代学进行了分析。从分别位于沉积物10.3米与12米深度的两处海洋岩芯中，获取了完整的冰后期沉积记录，同时还采集到冰碛物与冰前沉积物。目前（2000年），这些岩芯正处于分析过程中。若您对本项目或这批样本有任何疑问，请联系项目首席研究员，项目编号为ASAC1071——《东经50°至120°东南极海岸古环境研究》。本数据集包含以下字段：岩芯编号、采样站点、湖泊/海盆、纬度、经度、水深（米）、采样日期、岩芯回收长度（厘米）、衬管长度（厘米）、波茨坦存储库。
