The data consisted of sidescan sonar, sub-bottom profiler, magnetometer and multibeam echosounder data which had been acquired by Fugro Survey Limited and borehole logs recorded by Fugro Seacore Limited. This assessment focussed on the potential for remnant terrestrial landscapes that may contain terrestrial archaeological material dating to time of lower sea level; and the potential for the remains of maritime craft or aircraft of cultural heritage importance within the area that may be impacted upon by the proposed scheme. From the assessment of the borehole logs it appears that the scheme will pose no threat to palaeo-landsurfaces which have been inundated by marine transgression, as these deposits in the area lie below the proposed dredge depth of the scheme. Four sites of archaeological interest were identified from the geophysical data, one of which is a small wreck site while the remaining three are though to be debris which may prove to be relatively modern in origin. A further 34 sites were identified from the geophysical data although these are likely to be modern debris. The majority of these sites were magnetic anomalies for which no corresponding features could be identified in the sidescan sonar data and are therefore likely to be buried objects.
