The project objectives were to expand the previous UXO detection surveys completed in June 2011 and January 2012, under Osiris Projects Report numbers C11016 and C12001. The survey was carried out between 5th December 2012 and 30th January 2013. The current C12041 UXO survey involved modelling marine magnetic data to enable UXO and archaeological risk assessments to support the placement of inter array cables, with data acquisition comprising of multi-beam bathymetry, side scan sonar, pinger sub-bottom profiling and marine magnetic techniques, using Osiris Projects dedicated survey vessels, MV Bibby Tethra and MV Freja. This series contains Reports, UXO data, Geophysical Data and Charts.

Survey lines were acquired at 10m centres, towing a combination of two side scan sonar fish, over-the-side pinger and piggy-backed magnetometers, flown less than 3m above seabed at a 5m lateral separation. - Side scan sonar survey on either side of the export route, to assist with identifying objects to avoid whilst deploying anchors, using both the Bibby Tethra and Freja 11th-14th April 2013. - Additional nearshore acquisition of multibeam, magnetometer and side scan data in very shallow water along the export route, using MV Freja 16th January 2013 - Additional UXO on the beach area, using land survey techniques and land based magnetometers. - Survey of Amethyst pipeline to establish the relationship between potential UXO and pipeline exposures results contained within a separate report – C12036A. C12036A is available under series 2012 - 2013, Osiris Projects, Humber Gateway Offshore Wind Farm, Winter Geophysical Survey.
