Chironomid-based temperature reconstruction from Burgäschisee, Switzerland

The data herein presents a new chironomid record and associated chironomid-based temperature reconstruction covering the time interval 18,000-14,000 cal. BP from the lacustrine sediments of a kettle hole lake Burgäschisee, Switzerland. Chironomid assemblages show ecological turnover beginning 1,300 years before the onset of the Oldest Dryas / Bølling transition at ca. 14,700 cal. BP and associated increases in chironomid-based temperature reconstructions. These data also include non-chironomid invertebrate remains, including Ceratopogonidae, Daphnia and Ephemeroptera as well as Characean oospores.

本数据集呈现了一项新的摇蚊(Chironomid)记录及配套的基于摇蚊的温度重建结果，其覆盖时段为瑞士布尔加西湖（Burgäschisee）锅穴湖相沉积物中的18000~14000校准距今年(cal. BP)。摇蚊群落的生态更替始于约14700 cal. BP的最老仙女木期/博林暖期转换事件开始前1300年，且伴随基于摇蚊的温度重建值升高。本数据集还包含非摇蚊类无脊椎动物遗存，包括蠓科(Ceratopogonidae)、水蚤(Daphnia)、蜉蝣目(Ephemeroptera)以及轮藻卵囊孢子。
