An initial survey array was established based on the previous sampling effort. Following the acquisition of geophysical data in 2012, the survey array was reviewed, and locations were micro sited as appropriate. The following data were considered in the pre survey review of site locations:
Sidescan sonar and swathe bathymetry collected in 2012; Previous sampling locations from the East Anglia Zone studies; Previous on site observations of potential Sabellaria spinulosa reef; The Crown Estate (TCE) Conflict Check; and
