Insights into plate-boundary deformation are gained from the shear-wave splitting of local S phases that originate within lithosphere South Island, New Zealand. Analysis parameters land stations reveals changes in both delay times and fast azimuths with earthquake depth, earthquake-station back-azimuth initial polarization azimuth, suggesting laterally depth varying anisotropy. When average results examined as a whole via tomographic inversion spatial averaging, consistent patterns exist....
Abstract Local and regional S‐wave splitting in the offshore South Island of New Zealand plate‐boundary zone provides constraints on spatial depth extent anisotropic structure with an enhanced resolution relative to land‐based SKS studies. The combined analysis land measurements using tomography suggests shear dominates central northern Island. width this is about 200 km, but complicated by stress‐controlled anisotropy at shallow levels. In Island, a broader (>200 km) parallel associated...
Abstract Accurate, high‐resolution and sector‐specific greenhouse gas emissions information is increasingly needed for the development of local, targeted mitigation policies. We describe a detailed, spatially temporally resolved CO 2 data product, Mahuika‐Auckland, Auckland, New Zealand, based on Auckland's regional air inventories. Emissions are provided at 500 m spatial resolution 1‐hr time step, level detail not previously available any Zealand city. divide fossil fuel into six sectors...
Abstract. Groundwater age or residence time is important for identifying flow and contaminant pathways through groundwater systems. Typically, distributions are inferred via lumped parameter models based on measured tracer concentrations. However, due to cost constraints, tracers usually only sampled at a small percentage of the wells in catchment. This paper describes compares two methods increase number data points assist with validating from models. Two machine learning techniques...

The largest city in New Zealand, Auckland is home to roughly 1.5 million people -- one third of Zealand's population. Here we assemble a bottom-up inventory Auckland's fossil fuel carbon dioxide emissions from variety data sources. We use these estimates combination with the UrbanVPRM land surface model estimate net balance region. This work part larger CarbonWatch NZ project, which aims produce quickly enough assess and refine ongoing national efforts reach neutrality.
