Biological, chronological, geochemical and physical sedimentological data for the LP16 lake sediment record extracted from Lago Pato, Torres del Paine, Southern Chile in 2015

The dataset comprises of site data and multiproxy analyses of the LP16 lake sediment cores extracted from Lago Pato, a small lake basin at 51.3031 S, 72.6816 W and approx 33 m a.s.l., which is topographically separated from Lago del Toro in Torres del Paine (TdP). The data are used to constrain glacier dynamics and lake level change in the TdP and Ultima Esperanza region over the last approx 30,000 cal a BP (30 ka). Data for the LP16 sediment record consist of downcore measurements of biology, chronology, geochemistry, sedimentology proxy data collected extracted a current terrestrial shoreline in November 2015. This project was funded by the Natural Environment Research Council (NERC) through the British Antarctic Survey (BAS) and an UGent BOF bilateral collaboration project. RMcC was supported by Programa Regional R17A10002 and R20F0002 (PATSER) ANID. We gratefully acknowledge the University of Magallanes (UMAG) and the University of Santiago (Carolina Diaz) for assistance with fieldwork; the NERC/SUERC AMS Radiocarbon Facility for providing initial range-finder radiocarbon dates; the NERC Isotope Geosciences Laboratory (NIGL, now National Environmental Isotope Facility, NEIF, at the British Geological Survey) and Melanie Lang for stable carbon isotope analysis; Aberystwyth University (David Kelly), Durham University (Neil Tunstall and Christopher Longley) and Edinburgh University (Chris Hayward) for use of their core scanning and microprobe facilities and technical support.

数据集包含LP16湖泊沉积岩芯的站位数据和多指标分析（multiproxy analyses），该岩芯取自帕托湖（Lago Pato）——一个位于南纬51.3031°、西经72.6816°，海拔约33米（m a.s.l.）的小型湖盆，其在地形上与托雷斯德尔佩恩（Torres del Paine，简称TdP）的德尔托罗湖（Lago del Toro）相分离。这些数据用于限定过去约30000日历年前（cal a BP，30 ka）托雷斯德尔佩恩（TdP）和乌斯怀亚埃斯佩兰萨地区（Ultima Esperanza）的冰川动力学及湖面变化。LP16沉积记录的数据包括2015年11月从当前陆地海岸线采集的岩芯深度方向的生物学、年代学、地球化学和沉积学指标数据。本项目由自然环境研究理事会（NERC）通过英国南极调查局（BAS）以及根特大学（UGent）BOF双边合作项目资助。RMcC得到了区域计划R17A10002和R20F0002（PATSER）以及国家研究与发展局（ANID）的支持。我们衷心感谢麦哲伦大学（UMAG）和圣地亚哥大学（Carolina Diaz）提供的野外工作协助；感谢NERC/SUERC加速器质谱（AMS）放射性碳实验室提供的初始测距放射性碳年代数据；感谢NERC同位素地球科学实验室（NIGL，现更名为英国地质调查局下属的国家环境同位素设施NEIF）和Melanie Lang提供的稳定碳同位素分析支持；感谢阿伯里斯特威斯大学（David Kelly）、杜伦大学（Neil Tunstall和Christopher Longley）以及爱丁堡大学（Chris Hayward）提供的岩芯扫描和微探针设施及技术支持。
