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.
