The GRID seismic data was filtered with Petrel 2009.1 in order to remove noise and to emphasise the large-scale structures in the crust. A structural smoothing was first performed, with a large horizontal filter size (5.0) and a small vertical filter size (0.5) to bring out the subhorizontal features. A variance was then calculated, with a horizontal range of 3 and a vertical range of 25, in order to map the subvertical features in the seismic. The two filters are superimposed in this image, resulting in a significant reduction in noise. The profile is approximately 1:1 if assuming an average seismic velocity of 5 km/s. See the survey docs & links for a location map. See also the filtering of the BIRPS DRUM and MOIST lines.
