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.

为借助粒度、总有机碳（Total Organic Carbon, TOC）、C:N:S及硅藻等代用指标开展古气候研究，研究人员采集了湖泊与浅海沉积岩芯。这些岩芯已完成碳十四测年定年，部分贝壳碎片采用氨基酸地质年代学方法进行了分析。两处海洋岩芯分别在沉积层10.3米和12米深度处采获了完整的冰后期沉积记录，同时还获取了冰碛物与冰前期沉积物。目前（2000年），这些岩芯的分析工作正在进行中。若对该批样本或本项目有疑问，请联系首席研究员，项目编号ASAC1071——《东南极海岸50°E至120°E区域古环境》。本数据集包含以下字段：岩芯编号、采样站位、湖泊/海盆、纬度、经度、水深（米）、采样日期、采样设备、岩芯回收长度（厘米）、衬管长度（厘米）、波茨坦馆藏信息。
