{ "currentVersion": 10.71, "serviceDescription": "This dataset represents the Bouguer gravity anomaly calculated with a reduction density of 2.8 g/cc for ground gravity stations across New Brunswick.The dataset provides Bouguer anomaly values derived from reprocessed ground gravity measurements collected throughout New Brunswick. Using a reduction density of 2.8 g/cc, the Bouguer anomaly highlights variations in subsurface density and assists in interpreting regional geological structures, basin architecture, and intrusive bodies. The dataset is provided in the NAD83 NB Stereographic double projection and reflects consistent recalculation of Free Air and Bouguer corrections using SRTM-derived elevations and standardized processing parameters. It supports geological mapping, resource exploration, and crustal studies across the province.The data originated from ground gravity stations downloaded from the GSC server and reprocessed in September 2025. Marine stations were removed, SRTM topography was sampled for each station, and Free Air and Bouguer corrections were recalculated using a density of 2.8 g/cc. Terrain corrections were also computed using the same DEM. The resulting Bouguer anomaly values (Bouguer28) were exported and projected into NAD83 NB Stereographic to produce the dataset.Data created Sept 2025.", "name": "Geophysics_Gravity_Gradiometry_Compiled/Ground_compiled_Boug28", "description": "This dataset represents the Bouguer gravity anomaly calculated with a reduction density of 2.8 g/cc for ground gravity stations across New Brunswick.The dataset provides Bouguer anomaly values derived from reprocessed ground gravity measurements collected throughout New Brunswick.
