Service Description: This dataset represents the conformed Tz gravity field derived from the SWN_NBStereo (Lantern) FTG/AGG survey, gridded at 25 m resolution in NAD83 NB Stereographic projection.The dataset contains the vertical gravity component (Tz) from the SWN_NBStereo survey, corrected for long-wavelength deficiencies inherent to FTG/AGG measurements by conforming it to the GGMplus satellite gravity field. This conformed Tz field integrates high-frequency detail from the FTG survey with stable long-wavelength information from the satellite data, providing a physically consistent representation of both shallow and deep subsurface density variations. It enhances the interpretation of geological structures such as faults, intrusive bodies, lithological contacts, and basin geometries, supporting detailed structural mapping and mineral exploration. The dataset is delivered as a 25 m grid in NAD83 New Brunswick Stereographic projection.This raster was produced by reconstructing Tz from the measured tensor components of the SWN_NBStereo FTG/AGG survey, applying a 20 km high-pass filter to the FTG-derived Tz, applying a 20 km low-pass filter to the Bouguer anomaly from the GGMplus satellite gravity model, and combining both to generate the conformed Tz field. The final grid was interpolated at 25 m using a tensor-interpolation algorithm and exported as an ER Mapper (.ers) raster.Data created Sept 2025.
