An independent Conventional Gravity dataset is acquired as standard during FTG acquisition whilst sharing the technically superior stabilised platform of the FTG. Conventional gravity is essential for capturing the distinct long wavelength gravity anomalies associated with the deeper structures. When processed simultaneously with the gradiometry data a full spectrum broadband dataset is achieved, key for the mapping of both shallow and deep targets.
Scalar or conventional gravity meters measure the vertical component of gravity only. It can be acquired in the marine, terrestrial and airborne environments, using industry standard instrumentation – Metatek can acquire scalar gravity in all three environments.
In FTG acquisition, scalar gravity data from the Gravity Module Assembly (GMA) instrument is additionally processed independently from the FTG data and provides a conventional airborne gravity product. This dataset is used to verify that the gravity field produced by the integrated GMA and FTG data is representing the regional gravity correctly.
As well as acquisition, Metatek has processed over 2 million line-kilometres of conventional gravity data and completed close to 100 interpretation projects, often integrated with multiple additional geophysical and geological datasets. This makes Metatek easily the highest volume provider of combined FTG and scalar gravity globally.
