How depth below the surface influences groundwater biotic assemblages.

This research aimed to observe how depth below ground influences biotic assemblages within alluvial aquifers.See metadata (first tab of the data set) and Methods - Read Me.txt file for more information.~40 samples were collected on two separate occasions (6 months apart) from three alluvial aquifers (the Macquarie, Namoi and Hunter River catchments).Groundwater was pumped from wells and samples collected included water chemistry, eDNA (16S for prokaryotes, 18S for eukaryotes) and physical collection of stygofauna.

本研究旨在探究地下深度如何影响冲积含水层（alluvial aquifers）内的生物群落结构。更多信息请参见元数据（metadata，数据集的第一个标签页）及Methods - Read Me.txt文件。在两次独立采样（间隔6个月）中，从三个冲积含水层（分别位于麦夸里河、纳莫伊河和亨特河流域）采集了约40份样本。从水井中抽取地下水，采集的样本类型包括水化学特征、环境DNA（eDNA，原核生物采用16S测序，真核生物采用18S测序）以及洞穴生物（stygofauna）的实体样本。
