Southwest Greenland Lake Mixing Experiment

This data set is from a whole-lake mixing experiment conducted near Kangerlussuaq, Greenland over the summers of 2013 and 2014. The primary variable manipulated was temperature structure of the lake, and the primary response variables were the abundances of specific diatom taxa. Two lakes were employed in the experiment: one that served as a control in both years with no manipulation, and another that served as the experimental lake (Lake SS16) that was not manipulated in 2013 but was manipulated in 2014. Specifically, in 2014, a Solar Bee hydraulic lift system was installed to deepen the surface, mixed warm layer from 4 to 8 m in the experimental lake. Data provided here are the daily water column temperature values as well as the integrated (5 day time steps) diatom samples from sediment traps, listed by species in common to both lakes over both years.

本数据集源自2013年与2014年夏季在格陵兰康克鲁斯瓦格（Kangerlussuaq）附近开展的全湖混合实验。实验的核心操控变量为湖泊温度结构，主要响应变量为特定硅藻类群的丰度。本实验共设置两座湖泊：一座为两年均未施加任何操控的对照湖，另一座为实验湖SS16（Lake SS16）——该湖在2013年未进行操控，2014年则实施了水温调控。具体而言，2014年研究人员在该实验湖中安装了Solar Bee水力提升系统，将表层混合暖水层的深度从4米加深至8米。本次公开的数据包含每日水柱温度值，以及以5天为时间步长整合的沉积物捕集器硅藻样本，样本按两年间两座湖泊共有的物种进行分类整理。
