Identifying the sources and sinks of CDOM/FDOM across the Mauritanian Shelf and their potential role in the decomposition of superoxide (O2- )
(Frontiers Media, 2016-08-03)
Superoxide (O−2O2-) is a short lived reactive oxygen species (ROS) formed in seawater by photochemical or biological sources, it is important in the redox cycling of trace elements and organic matter in the ocean. The ...
Methods and techniques employed to monitor and manage carbon capture and sequestration (CCS) induced seismicity
(GNS Science, 2016)
This report discusses the topic of induced seismicity resulting from the operations of subsurface CO2 injection at Carbon Capture and Storage (CCS) sites. The potential for induced seismicity to occur in CCS projects is ...
Exploring structure and stress from depth to surface in the Wairakei Geothermal Field, New Zealand
(International Geothermal Association, 2016-02-22)
Structures such as fractures and faults have an important role as fluid flow pathways in geothermal fields, as the reservoir rocks hosting geothermal resources can often have little to no intrinsic permeability. As such, ...
Geothermal structural geology in New Zealand: Innovative characterisation and micro-analytical techniques
(International Geothermal Association, 2016-11-23)
Many of New Zealand's geothermal reservoirs are hosted in rocks with low intrinsic permeability. As such, successful development of these resources relies on understanding the role subsurface structures, such as fractures ...
Damaged beyond repair? Characterising the damage zone of a fault late in its interseismic cycle, the Alpine Fault, New Zealand
X-ray computed tomography (CT) scans of drill-core, recovered from the first phase of the Deep Fault Drilling Project (DFDP-1) through New Zealand's Alpine Fault, provide an excellent opportunity to study the damage zone ...
Calcite sealing in a fractured geothermal reservoir: Insights from combined EBSD and chemistry mapping
Fractures play an important role as fluid flow pathways in geothermal resources hosted in indurated greywacke basement of the Taupo Volcanic Zone, New Zealand, including the Kawerau Geothermal Field. Over time, the ...
