BigT is derived by converting TMI to magnetic field components and calculating the vector magnitude, and the difference with TMI highlights areas of potential remanent magnetization. The dataset is provided in NB Stereographic Double, NAD83.The grid was created from the Restigouche 1997 survey by microlevelling the TMI, calculating BigT from magnetic field components, and then subtracting the TMI values. The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.", "name": "Geophysics_Aeromagnetic_Individual_Surveys/Restigouche_BigT_TMI_diff", "description": "A grid showing the difference between BigT and total magnetic intensity (TMI) for the Restigouche 1997 survey.This dataset represents the difference between BigT and TMI (BigT_TMI_diff) for the Restigouche airborne magnetic survey in New Brunswick.
