MOIST (Moine and Outer Isles Seismic Traverse) from the BIRPS surveys (British Institutions Relfection Profilig Syndicate). This was the first line shot by BIRPS, and was recorded at sea just north of the coast of Scotland. It crosses the northern margin of the Caledonian orogen, and was shot and processed by the Western Geophysical Company using a high pressure airgun system, recording to a maximum of 15s (appx 40-45 km depth). MOIST used a small source 905cubic inch air gun, at 4500 psi shot point interval 50 m to achieve 15 s TWT recording. Source at 12 m depth. Typically 36 airguns among 6 arrays. The survey was processed using one single operator for deconvolution before and after stack.

The MOIST 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 o...
