2014, SAND Geophysics Norfolk Marine, Scroby Sands, Multibeam Bathymetry and Sidescan Sonar Survey

A bathymetric and sidescan survey at Scroby Sands windfarm site including 20m coverage around each of the 30 wind turbines, a 10m corridor along cables and around the base of the met mast was conducted between 1 September 2014 and 17 September 2014. The acquired bathymetry data shows the effect of the scour protection where installed and the effects of scour around the turbines with no protection installed. Sidescan sonar data identified a number of cable exposures, predominantly close to turbines, which have not changed considerably since the previous year. The data is provided as georeferenced drawings using British National Grid horizontal datum. Vertical Datum or Chart Datum was taken as 1.56m below Ordnance Datum (Gorelston).
