Chironomid abundances of sediment core FLB from Lake Flocktjärn (Sweden) from 2014

This dataset provides chironomid counts for the Holocene sediment sequence retrieved from Lake Flocktjärn (Sweden) in 2014. The counts are presented against both depth (m) and age (ka BP). A total of 44 samples were counted. The chironomid counts provide information about changes in the invertebrate fauna of the lake. Cores were retrieved from the lake using a 1-m long handheld piston corer deployed from a floating coring platform during field work in May 2014. Volumetric samples were obtained from splits of the core and processed in the laboratory (University of Amsterdam, the Netherlands) using standard protocols.

本数据集提供了2014年从瑞典弗洛克蒂恩湖（Lake Flocktjärn）获取的全新世沉积序列的摇蚊（chironomid）计数数据。该计数结果同时以深度（米）和年龄（ka BP）两种维度呈现，共计分析44个样本。摇蚊计数数据可反映该湖泊无脊椎动物群落的变化情况。2014年5月的野外工作中，研究人员依托浮动钻探平台，使用1米长手持式活塞取芯器从该湖采集了沉积岩芯。研究人员从岩芯分样中获取体积样本，并于荷兰阿姆斯特丹大学（University of Amsterdam）实验室按照标准实验流程完成了样本处理。
