TVAS Geophysical Survey Developments

TVAS are excited to announce the expansion of our geophysical survey services with the recent addition of a non-magnetic cart.

With this new piece of equipment from Bartington Instruments we can now complete larger magnetometer surveys at four times the rate that was previously achievable. The cart mounts two Bartington Grad 601-2 gradiometers, which, at 1m spacing, gives a coverage of 4m per traverse. In addition to this, real-time centimetre-accuarte GPS positioning allows the survey to be undertaken without having to first set up a site grid. As with all our surveys, we are able to create greyscale and interpretation plots for the gradiometer data which is presented on Ordnance Survey mapping to accompany the survey report.
