data indicates the presence of an entire wreck lying approximately NE-SW to the south-west of a shoaler sand wave, the crest of which is generally 1m higher than the wreck. This is recorded as a Live wreck. The difference in dimensions between 1995 data and 2013 data could be due to exposure of the wreck due to mobile seabed sediments.


1.2.11 Debris 60.


There are 70 pieces of debris recorded within the East Anglia THREE site (see Appendix 17.3). All of these pieces of debris have been assigned an archaeological potential rating of A2 due to their anthropogenic appearance and characteristics. The anomalies vary in size and character and are described in Appendix 17.3. A selected range of these debris remains are described below.


61.


The smallest piece of debris identified in the East Anglia THREE site is 76101 interpreted to be associated debris from recorded wreck 71008. The debris has dimensions of 0.6m length, 0.5m width and no measurable height. This appears as a small, rectangular shaped dark reflector with no shadow in the sidescan sonar data and is interpreted as being likely wreckage or cargo swept away from the vessel, situated 50m from the remains. There are a number of pieces of debris inferred to be associated with this wreck identified within 100m of the remains (76096, 76099; 76100; 76102; 76103; 76104 and 76105). Magnetic fluctuations have been recorded over this wreck site and as such some of these debris remains could be composed of ferrous material.


62.


The largest piece of debris recorded on site is located in the central western extent of the East Anglia THREE site (76083). The debris remains have dimensions of 19.4m length, 1.3m width with no measurable height and is isolated on a rough and sand wave rich part of the seabed. The remains are visible as a long and irregular shaped diffuse dark reflector with no shadow. The debris is located perpendicular to the sand waves and looks as though it could be broken up or partially buried by sandy sediments. This debris has a medium sized magnetic anomaly associated with it and as such could be made up of ferrous material.


63.


There are 17 pieces of debris that are inferred to be associated with three separate wreck remains within the East Anglia THREE site as described above (71008; 71012 and 76145).


64.


Eight further pieces of debris have been grouped with magnetic anomalies (see Appendix 17.3). 76060 is a curvilinear piece of debris that is possibly broken in two or partially covered by sand waves. This has dimensions of 5.3m length, 1m width
