  • The Geothermal surface features database is maintained by GNS Science to provide a time-series database of measurements/observations/locations of geothermal surface features from high temperature and low temperature geothermal fields in New Zealand. The database includes time-series observations and measurements of geothermal surface features in NZ that include temperature, location, description, feature types and flows. There is an intention to expand this to water/gas chemistry. The database is divided into two datasets: 1) BOPRC Geothermal Surface Feature Database - Public access. This contains data collected for Bay of Plenty Regional Council for features in the BOP region only. Although collected and entered for the BOPRC under commercial contracts, the BOPRC make this data available in the public domain. 2) Natural Thermal Feature/Springs of New Zealand. This dataset contains data for the rest of NZ. Data is only sourced from publicly available documents and all data has a reference. Both datasets are accessed via the GNS GGW web interface on the GNS website. DOI: https://doi.org/10.21420/BPMA-D502 Cite as: GNS Science, & Bay of Plenty Regional Council - Toi Moana. (2015).

  • The Aquifer Potential Map is a preliminary map (version 1.0). This work was carried out as part of the GNS Science Groundwater Resources of New Zealand research programme, and future plans within this research programme include the refinement and update of this map. In its current form, the map is considered suitable for refining surficial aquifer boundaries on the regional scale where these boundaries have not been updated since 2001. Future updates of the dataset will reduce the uncertainty and extend the applicability of the data set. The New Zealand 1:250,000 geological map (QMAP) lithological and chrono-stratigraphic information (i.e., main rock type; geological age; and secondary rock type) were used to carry out a nationwide assessment of surficial hydrogeological units and their properties. A number of subsequent map products were produced. The work is described in Tschritter et al. 2017. One of these, the Aquifer Potential map, shows a good match with the most recent New Zealand national aquifer boundary dataset of Moreau and Bekele (2015). Additionally, the Aquifer Potential map provides a quick and simple way to communicate basic large-scale hydrogeological information.

  • This hydrogeological system GIS dataset provide a nationally-consistent basis for hydrogeological mapping in New Zealand. Hydrogeological systems are defined here as geographical areas with broadly-consistent hydrogeological properties, and similar resource pressures and management issues. The ‘NZ_hydrogeologicalsystem_polygon.shp’ provides seven hydrogeological attributes as follows: unique name (HS_name), unique identification (HS_id), system type (HS_type), coastal information (HS_coast), aquifer overview (HS_overview), geology and age group (HS_geo_gr) and geology and age descriptor (HS_geo_age). Nine system types are identified (see figure below). The ‘NZ_hydrogeologicalsystem_boundary.shp’ attribute table identifies, the source and methods of boundary delineation. Attribute names, descriptions and values for both datasets are detailed in Moreau et al. 2019. DOI: https://doi.org/10.21420/HTZ8-Z141 Cite as: GNS Science. (2018).

  • The GGW database is operated and maintained by the Institute of Geological and Nuclear Sciences Limited (GNS Science). It contains geochemical (chemistry and sampling), hydrological, geological and/or geophysical information for Sites (Features) in New Zealand. Included in the database are the datasets for the National Groundwater Monitoring Programme (NGMP) and Wairaikei Analytical, Recording, Thermo Dynamic System (WARTS) projects maintained and operated by GNS Science. The database design was adapted for New Zealand from Australian Standards. DOI: https://doi.org/10.21420/9QTA-4884 Cite as: Geothermal and GroundWater Database. 2005–.

  • Over many years, GNS Science has developed a large number of datasets, spatial and otherwise, to characterise the petroleum systems within the NZ Exclusive Economic Zone and Extended Continental Shelf. These include petroleum exploration data mined from open file NZP&M Petroleum Reports (PR's) and GNS Science research data generated from reviews of PR's. It also includes data and interpretations developed from GNS Science research programmes, including reprocessing of seismic data, borehole log interpretation and processing, geological reconstructions, 3D and 4D models, etc. The Petroleum Basin Explorer web application is a good starting point for exploration GNS Science petroleum systems data. A lot of this data has been condensed into the public Atlas of Petroleum Prospectivity (see associated record) but other data sets are private to GNS Science.

  • The WARTS database was maintained by GNS Science to provide a time-series database of water and gas chemistry results from geothermal surface features, volcanos and geothermal bores analysed by DSIR (Chemistry division). The database includes time-series analytical measurements (water chemistry, gas chemistry and limited field measurements of temperature and pressure for bores) made by DSIR of geothermal surface features, volcanos and geothermal bores in NZ and internationally – anything the water chemistry laboratory based at Wairakei analysed. The dataset contains both samples collected for research and for commercial purposes, with no distinction within the dataset of what was research and what was commercial.
