The TMI_AS highlights the positions and edges of magnetic sources independent of magnetization direction, supporting detailed geological and structural interpretation. The dataset is provided in NB Stereographic Double, NAD83.The grid was created from the Marrtown 2004 survey by microlevelling the TMI, converting it to a grid, and calculating the total gradient (analytic signal) from the TMI values. The final grid is provided in NB Stereographic Double, NAD83.Data created Sept 2025.", "name": "Geophysics_Aeromagnetic_Individual_Surveys/Marrtown_TMI_AS", "description": "A grid of the total gradient (analytic signal) of total magnetic intensity (TMI) for the Marrtown 2004 survey.This dataset represents the analytic signal (total gradient) of TMI for the Marrtown airborne magnetic survey in New Brunswick.
