 "description": "A grid of BigT (total magnetic field magnitude) for the Tobique River 1985 survey.This dataset represents BigT, the total magnetic field magnitude, for the Tobique River airborne magnetic survey in northern New Brunswick. BigT is calculated by converting total magnetic intensity (TMI) to magnetic field components (X, Y, Z) and computing the vector magnitude, providing a clear overview of magnetic anomalies and sources. The dataset is provided in NB Stereographic Double, NAD83.The BigT grid was created from the Tobique River 1985 survey by microlevelling the TMI, converting it to magnetic field components, and calculating the vector magnitude (√(X² + Y² + Z²)). The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.",
