{ "currentVersion": 10.91, "serviceDescription": "This dataset represents the Txx component of the gravity tensor derived from the Bell BMC2010 FTG/AGG survey in New Brunswick, gridded at 25-meter resolution in NAD83 NB Stereographic projection.The dataset provides the Txx tensor component extracted from the processed gravity gradiometry data of the Bell BMC2010 FTG/AGG survey. The Txx component captures variations in the second derivative of the gravity field along the X-axis, which can be used to infer subsurface density contrasts and structural features. The dataset supports high-resolution geophysical interpretation, structural mapping, and mineral exploration. It is provided in NAD83 NB Stereographic double projection with a 25-meter grid spacing.The dataset was produced by constructing a gravity tensor from the Bell BMC2010 FTG/AGG raw profile data processed with a density of 2.8 g/cc and interpolating the tensor into a regular 25-meter grid. The Txx component was extracted from the full tensor, representing the second derivative of gravity along the X-axis. The final Txx grid was exported in ER Mapper format for use in geophysical analysis and interpretation.Data created Sept 2025.", "name": "Geophysics_Gravity_Gradiometry_Individual_Surveys/Bell_BMC_Txx", "description": "This dataset represents the Txx component of the gravity tensor derived from the Bell BMC2010 FTG/AGG survey in New Brunswick, gridded at 25-meter resolution in NAD83 NB Stereographic projection.The dataset provides the Txx tensor component extracted from the processed gravity gradiometry data of the Bell BMC2010 FTG/AGG survey.
