We present a dataset of subfossil chironomid assemblages in the MUT-10 sediment core obtained from the high alpine lake Mutterbergersee in the Austrian Alps in 2010. The data were presented in the research article by Ilyashuk et al. (2019) "The Little Ice Age signature in a 700-year high-resolution chironomid record of summer temperatures in the Central Eastern Alps". In addition to the results of the chironomid analysis of 100 sediment samples presented in this article, we also include chironomid assemblage data from an additional 48 sediment samples that complement this dataset. The data includes raw chironomid counts, percent abundance of chironomid taxa, as well as mean July air temperature estimates derived from the chironomid record based on a chironomid-temperature transfer function. We also provide information on age-dating of the sedimentary sequence. Given the high temporal resolution and the robust age-depth model of the record, the chironomid-based reconstruction of temperature since AD 1300 provides a detailed documentation of climate change in the Eastern Alps from the Little Ice Age onwards and can be used for comparison with other independent proxy-based climate reconstructions. In addition to the data, we detail the sample processing for subfossil chironomid analysis and provide a detailed description of the reconstruction technique used for producing chironomid-based quantitative temperature inferences.
我们展示了一个亚化石摇蚊组合数据集，该数据集来自2010年从奥地利阿尔卑斯山的高山湖泊穆特贝格湖获取的MUT - 10沉积岩芯。这些数据发表在伊利亚舒克等人（2019年）的研究文章《中东阿尔卑斯山700年高分辨率摇蚊记录中的小冰期特征：夏季温度》中。除了本文中呈现的100个沉积物样本的摇蚊分析结果外，我们还纳入了另外48个沉积物样本的摇蚊组合数据，以补充该数据集。数据包括原始摇蚊计数、摇蚊类群的相对丰度，以及基于摇蚊 - 温度传递函数从摇蚊记录中得出的7月平均气温估计值。我们还提供了沉积序列年代测定的信息。鉴于该记录具有高时间分辨率和稳健的年龄 - 深度模型，基于摇蚊的公元1300年以来温度重建提供了自小冰期以来东阿尔卑斯山气候变化的详细记录，可用于与其他基于独立代用指标的气候重建进行比较。除了数据之外，我们详细说明了亚化石摇蚊分析的样本处理过程，并提供了用于生成基于摇蚊的定量温度推断的重建技术的详细描述。
