Investigating the Magma Reservoir of Taupō Volcano Using Receiver Functions

Geochemistry, Geophysics, Geosystems
The Taupō Volcanic Zone (TVZ), one of the most active volcanic systems globally, poses significant hazards. To improve our understanding of crustal structure and implications for hazards, we apply P‐to‐S receiver function analysis, supplemented by S‐to‐P

A genus in the bacterial phylum Aquificota appears to be endemic to Aotearoa-New Zealand [PDF]

Nature Communications
Allopatric speciation has been difficult to examine among microorganisms, with prior reports of endemism restricted to sub-genus level taxa. Previous microbial community analysis via 16S rRNA gene sequencing of 925 geothermal springs from the Taupō ...

Tracking Magma‐Crust‐Fluid Interactions at High Temporal Resolution: Oxygen Isotopes in Young Silicic Magmas of the Taupō Volcanic Zone

Geochemistry, Geophysics, Geosystems, 2023
Oxygen isotopes are useful for tracing interactions between magmas, crustal rocks and surface‐derived waters. We use them here to consider links between voluminous silicic magmatism and large‐scale hydrothermal circulation in New Zealand's central Taupō ...

Multi-method constraints on the age and timescale of silicic small-volume eruptions of Puketerata Volcanic Complex, Taupō Volcanic Zone, New Zealand

Earth, Planets and Space, 2023
Accurate dating of young eruptions from explosive volcanoes is essential for forecasting future eruptions and for defining the hazardscape of volcanic fields.

Acoustic Predictors of Active Fluid Expulsion From a Hydrothermal Vent Field, Offshore Taupō Volcanic Zone, New Zealand

Frontiers in Earth Science, 2022
Understanding fluid expulsion is key to estimating gas exchange volumes between the seafloor, ocean, and atmosphere; for locating key ecosystems; and geohazard modelling.

Hydrothermal Cooling as a Requirement for Short Storage of Silicic Magmas

Geochemistry, Geophysics, Geosystems, 2021
Large (>50 km3) magma bodies that contribute to caldera‐forming eruptions in the Taupō Volcanic Zone (TVZ), New Zealand have shown evidence for crystallization and storage on the order of decades to centuries prior to eruption.

Effects of hydrogeochemistry on the microbial ecology of terrestrial hot springs

Microbiology Spectrum, 2023
Temperature, pH, and hydrochemistry of terrestrial hot springs play a critical role in shaping thermal microbial communities. However, the interactions of biotic and abiotic factors at this terrestrial-aquatic interface are still not well understood on a

Tectonic classification of vertical crustal motions – a case study for New Zealand

Contributions to Geophysics and Geodesy, 2016
We investigate the relationship between vertical crustal motion and tectonic block configuration. The study is conducted along the active tectonic margin between the Australian and Pacific tectonic plates in New Zealand with a well-defined tectonic block

Matrix permeability of reservoir rocks, Ngatamariki geothermal field, Taupo Volcanic Zone, New Zealand

Geothermal Energy, 2018
The Taupo Volcanic Zone (TVZ) hosts 23 geothermal fields, seven of which are currently utilised for power generation. Ngatamariki geothermal field (NGF) is one of the latest geothermal power generation developments in New Zealand (commissioned in 2013 ...

Genomic adaptations enabling Acidithiobacillus distribution across wide-ranging hot spring temperatures and pHs

Microbiome, 2021
Background Terrestrial hot spring settings span a broad spectrum of physicochemistries. Physicochemical parameters, such as pH and temperature, are key factors influencing differences in microbial composition across diverse geothermal areas. Nonetheless,
