Gravity Survey Data

A catalogue of over 40,000 gravity survey observations in New Zealand, including free air, Bouguer and isostatic gravity anomalies has been assembled. These data have been assembled from survey measurements mostly made by Geophysics Division, Department of Scientific and Industrial Research, (now GNS Science) since the 1940s using a variety of meters. Some gravity data has been contributed by petroleum explorers and universities. In 2004 all data were uniformly reprocessed using GNS Science software and tied to primary gravity sites the New Zealand Reference Gravity Stations ( https://doi.org/10.21420/96Q5-8581?x=y ).


This database is http://dx.doi.org/10.21420/DRDW-VC72?x=y .

Purpose

A database of historical gravity surveys in New Zealand.


This resource is a map layer used in conjunction with the New Zealand Petroleum Basin Explorer (PBE). PBE is an interactive web-based GIS tool that allows users to discover and access a wide range of exploration and research geoscience data.
