  • The NGMP is a groundwater quality dataset, collected regularly through collaborations with regional council personnel from 110 sites across all 15 regions of New Zealand, since 1990. The network attained national coverage in 1998. Information stored in the NGMP database includes groundwater source location, groundwater quality indicators (e.g. major ions, nutrients, dissolved metals), groundwater age tracer measurements (e.g. chlorofluorocarbons, tritium, and sulphur hexafluoride), mean residence time age interpretation at each site and key hydrogeological properties, where available. Samples are collected according a national, dedicated protocol (published in 1999, updated in 2006, national environmental Monitoring Standards for discrete water quality 2009). The NGMP assets are preserved and enhanced through dedicated quality assurance procedures, maintaining the viability and longevity of the network, adding new samples and data, undertaking research to enhance the assets, and ensuring that curation facilities are appropriate for long-term protection and availability. The NGMP dataset is stored in the broader Geothermal Groundwater Database (GGWD) DOI: https://doi.org/10.21420/NY6Y-VZ29 Cite data as: GNS Science. (2022).

  • The GeoNet earthquake catalogue contains the technical information of all known seismological events. The dataset includes information about the events source parameters such as hypocenter, magnitude, arrival time of seismic phases as well as velocity model used and uncertainties in the parameters. Since the 1930's, earthquakes in the catalogue have been determined by instrumental records. Prior to that, estimates were made from oral and written records. At present, a densified network of weak motion and strong motion sensors is used nationally to monitor events in regions that are affected by large seismic activity and volcanism. Around 20000 events are recorded every year in the catalogue. GeoNet observations and earthquake source parameters are currently used for rapid response, risk assessment and research purposes.

  • The New Zealand National Seismograph, Acoustic and Coastal Tsunami Gauge Networks digital time-series (waveform) data are archived and publicly available. The time-series include both permanent and some temporary network deployments and are distributed using a number of standard formats and access options. The data comprise readings recorded by seismometers, tide gauges and microphones since the commencement in September 1986 of digital recording in New Zealand. Instrument and site information are held in the GeoNet public metadata repository.

  • A moment tensor describes the source parameters of an earthquake such as the focal mechanism (the geometry of how the crust ruptured in the earthquake) and the seismic moment (the amount of energy released). Since August 2003 when sufficient broadband seismometers were deployed, GeoNet has been able to routinely compute moment tensor solutions for New Zealand earthquakes with M > ~4. The CSV file of moment tensor solutions is updated when a moment tensor solution is calculated. Moment Tensor Solutions can be found in Github here: https://github.com/GeoNet/data/tree/main/moment-tensor. DOI: 10.21420/MMJ9-CZ67 Cite as: GNS Science. (2006).
