This library is a subset of the master library of all data lodged to the Crown which is held by the Ministry of Commerce, Resource Information Unit. There are computer indexes to this library along with digital databases of well logs, seismic lines and shot point location data. Three datasets that characterise the hydrological, geological, geochemical and geophysical properties of geothermal features and geothermal fields of New Zealand. Chemical Database - Over 10,000 individual sample records from New Zealand and overseas geothermal features. Each record contains analytical data and sampling information.
Some recent data are proprietary.
The data cover most of the Taupo Volcanic Zone and an area around the Ngawha geothermal field in Northland. These data are used to delineate geothermal fields and provide information on the extent of thermal water down to depths of about 500m. The imagery is collected and sorted on standard VHS-PAL videotape. Several hundred digitised images have been generated and are available on floppy disk. The data provide surface temperature information on the surveyed areas and baseline data for monitoring change in geothermal features.
