Service Description: This dataset represents the complete Bouguer gravity anomaly (density 2.8 g/cc) derived from ground gravity measurements across New Brunswick.The dataset provides complete Bouguer anomaly values calculated from reprocessed ground gravity data collected throughout New Brunswick. The complete Bouguer anomaly incorporates the Bouguer correction and terrain correction, both computed using a reduction density of 2.8 g/cc. This anomaly enhances the accuracy of subsurface density interpretations, particularly in areas with significant topographic relief. It is well suited for regional geological mapping, structural interpretation, and mineral exploration studies. The dataset is delivered in NAD83 NB Stereographic double projection and reflects consistent recalculation of corrections using SRTM topography and standardized processing workflows.Ground gravity station data were downloaded from the GSC server and reprocessed in September 2025. Marine stations were removed, and SRTM elevation data were used to recompute Free Air and Bouguer corrections at each station using a density of 2.8 g/cc. Terrain corrections were calculated using the same DEM. The complete Bouguer anomaly was then obtained by adding the Bouguer anomaly and terrain correction. These values were exported and projected into NAD83 NB Stereographic to produce the dataset.Data created Sept 2025.
