description: This dataset represents the regional component of the complete Bouguer gravity anomaly (density 2.8 g/cc) for New Brunswick, derived from the GGMplus satellite gravity model and gridded at 100-meter resolution in NAD83 NB Stereographic projection.The dataset provides the long-wavelength regional component of the complete Bouguer gravity anomaly calculated from the GGMplus satellite gravity model. This regional anomaly emphasizes broad-scale crustal density variations and suppresses short-wavelength, shallow features. It is intended to support regional geological interpretation, crustal studies, and integration with residual anomaly analyses for mineral exploration. The dataset is provided in NAD83 NB Stereographic double projection with 100-meter grid spacing.The dataset was produced from the GGMplus satellite gravity model, which provides Free Air anomalies. Bouguer corrections and terrain corrections were applied using SRTM topography and a density of 2.8 g/cc to produce the complete Bouguer anomaly grid. The regional component was then obtained by applying an upward continuation filter to isolate long-wavelength gravity variations. The final grid was resampled to 100 meters and projected into NAD83 NB Stereographic, producing the dataset.Data created Sept 2025.
