Service Description: A grid showing the difference between BigT and total magnetic intensity (TMI) for the St. Stephen 2001 survey.This dataset represents the difference between BigT and TMI for the St. Stephen airborne magnetic survey in southern New Brunswick. 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 BigT_TMI_diff grid was created from the St. Stephen 2001 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.
