Description

Emu Ltd were commissioned by Greater Gabbard Offshore Wind Ltd to undertake at geophysical survey over the proposed offshore Greater Gabbard windfarm site. The export cable route and a landfall survey area extending approximately 3km offshore was also surveyed. Two additional transect lines across the Inner Gabbard bank were also surveyed. The survey was implemented to determine seabed topography and morphology, to identify the nature of the seabed sediments, to identify the thickeness of superficial sediments to London Clay and to identify the location, extent and nature of any impediments to the laying or burial of the cable. The survey was carried out between 26th May and 9th June 2005 and involved the use of swath bathymetric surveying combined with sidescan sona, seismic sub bottom profiling and magnetometer survey techniques. Preliminary analysis of the data identifies vast expanses of flat featureless seabed with areas of sandwaves and mega ripples also identified. A known wreck site was also identified from the magnetometer survey.
