Stygobiont Diversity in the San Marcos Artesian Well and Edwards Aquifer Groundwater Ecosystem, Texas, USA [PDF]
Diversity, 2021 The Edwards Aquifer and related Edwards-Trinity Aquifer of Central Texas, USA, is a global hotspot of stygobiont biodiversity. We summarize 125 years of biological investigation at the San Marcos Artesian Well (SMAW), the best studied and most biodiverse

Rayleigh wave and well head response to calculate porosity in the Edwards aquifer of south-central Texas, USA [PDF]
Acta Carsologica, 2020 We use the magnitude and centroid period of Rayleigh wave along with the amplitude of fluctuations of water level in a well to calculate effective porosity of a karst aquifer at the site scale.

Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments. [PDF]
Environ Microbiol RepOverview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.
