description: This dataset represents the Tyy component of the gravity tensor derived from the SWN_NBStereo (Lantern) FTG/AGG survey, gridded at 25 m resolution in NAD83 NB Stereographic projection.The dataset contains the Tyy tensor component extracted from the reconstructed gravity tensor of the SWN_NBStereo survey. Tyy represents the second derivative of the gravity field along the Y-axis, capturing lateral density variations in the subsurface. This component is useful for mapping faults, lithological contacts, intrusive bodies, and other structural features, supporting high-resolution structural interpretation and mineral exploration. The dataset is provided as a 25 m grid in NAD83 New Brunswick Stereographic projection.This raster was produced by processing the SWN_NBStereo FTG/AGG profile data using a density of 2.8 g/cc, reconstructing the full gravity tensor from the measured components, interpolating the tensor to a 25 m grid using a tensor-interpolation algorithm, and extracting the Tyy component. The final grid was exported in ER Mapper (.ers) format.Data created Sept 2025.
