Pollen data from the margins of Lake Tiefer See / north-eastern Germany from sediment core TS-9

The data sets includes pollen records from 16 sediment cores taken at the margins of Lake Tiefer See / north-eastern Germany. The sediment cores were primarily studied to produce a lake level reconstruction for Tiefer See. Pollen analysis was applied for pollen stratigraphic dating of the sediments in comparison with a high resolution pollen record from the centre of Lake Tiefer See. Moreover, pollen analysis was also used to infer past water levels trough time at the core locations. The sediment cores for pollen analysis were taken and analysed between 2012 and 2017, either from the ice or a raft. For coring either a piston corer or a chamber corer were used. Only three of the sediment records (TS-2, TS-3, TS-17) cover the Holocene largely continuously, the others mainly only cover early- or late Holocene sections.

本数据集包含采自德国东北部蒂费尔湖（Lake Tiefer See）沿岸的16根沉积物岩芯（sediment cores）的孢粉记录（pollen records）。本研究的核心目标为重建蒂费尔湖的古湖平面变化，所涉及的沉积物岩芯均服务于该研究目的。研究中通过孢粉分析（pollen analysis）完成沉积物的孢粉地层定年，并与蒂费尔湖湖心的高分辨率孢粉记录进行对比。此外，孢粉分析还被用于反演各岩芯采样点随时间演化的古水位状况。用于孢粉分析的沉积物岩芯采集与分析工作于2012至2017年间完成，采样方式涵盖冰上采样与筏上采样两种。岩芯采集采用活塞式取芯器（piston corer）或舱式取芯器（chamber corer）。本次采集的沉积物记录中，仅TS-2、TS-3与TS-17三根岩芯基本完整覆盖全新世（Holocene）地层，其余岩芯仅主要覆盖早全新世或晚全新世的部分地层。
