Based on the acquired survey data the seabed topography and the shallow geology and stratigraphy within the site are interpreted approx. to the first multiple. Some of the interpretation is uncertain due to limited seismic penetration/ resolution. The project decided to execute a new survey campaign in 2013, which was undertaken by Gardline. Its main purpose will be: - To acquire multi-channel seismic data for processing and removal of the multiples to enable a reliable interpretation of the stratigraphy down to (and in) the chalk, - To acquire ultra-high 1channel seismic data to enable strengthening of the existing stratigraphic interpretation of the shallow geology. - To establish a best possible geological model based on the old and new seismic and geotechnical data. - To evaluate possible geohazards like shallow gas or boulder layers within the upper 100 m of sediments, or areas of poor bearing capacity.

A BASE surface is a geo-referenced image of a multi-attributed, weighted mean surface. The gridding technique used was a combination of range and swathe angle weighting. The range weight was inversely proportional to the distance from the node (the position of the node was determined during the creation of the fieldsheet): soundings closer to the node were given more weighting. The swathe angle weighting ensured that higher value was given to beams from the inner part of the swathe than to outer beams from adjacent lines. The surface was created using a single resolution of 2m x 2m, which was determined by several factors including; system, water depth, line spacing and data quality. The child layers: mean, shoal, deep, density and standard deviation were reviewed for outstanding noise, artefacts and density, which were then updated and finalised for export.
