|
A grid of the total magnetic intensity difference (BigT) for the Columbia 2000 survey.This dataset represents BigT, the total magnetic intensity difference, for the Columbia 2000 airborne magnetic survey in New Brunswick. BigT is calculated by converting TMI to magnetic field components (X, Y, Z) and computing the vector magnitude, providing a clear view of magnetic anomalies and sources. The dataset is provided in NB Stereographic double (NAD83).The BigT grid was created from the Columbia 2000 survey by microlevelling the TMI (Mag_miclev), 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. |
