Low-temperature geothermal systems (>30°C and up to nominally ~70°C) are a largely underexplored component of New Zealand’s geothermal resource base. While high-temperature systems have been explored and exploited for decades, low-temperature geothermal systems have been sidelined, despite being useful in areas such as horticulture, aquaculture, and industrial processing. One of the impediments to utilising low-temperature geothermal resources is that they are difficult to identify and monitor within groundwater systems using existing geophysical approaches.
This PhD project aims to solve this issue by integrating microbial ecology and extremophile microbiology with hydrogeochemistry and modelling to develop a new methodology to monitor and map low-temperature geothermal resources in groundwater systems in NZ. This PhD project will exploit key taxonomic and metabolic characteristics of extremophilic microorganisms as sensitive tracers of transient geothermal–groundwater interactions.
