This dataset represents the Tyy component of the gravity tensor derived from the Bell BMC2010 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 generated from the Bell BMC2010 FTG survey. Tyy is the second vertical derivative of the gravity field in the Y direction and is sensitive to lateral density variations, making it useful for mapping structural trends, geological boundaries, and subsurface features that produce contrasts along the survey’s Y-axis. It enhances medium- to short-wavelength anomalies associated with faults, lithological contacts, and intrusive bodies. The dataset is provided as a 25 m grid in NAD83 New Brunswick Stereographic projection.This raster was produced by processing the original FTG profile data using a density of 2.8 g/cc, reconstructing the full gravity tensor from the measured components, gridding the tensor using a tensor-interpolation algorithm at 25 m resolution, and extracting the Tyy component from the resulting tensor grid. It is delivered as an ER Mapper (.ers) raster.Data created Sept 2025.
