previous surveys this was primarily used for the identification and archaeological discrimination of anomalies.

71005, 71013, 71014 and 71015 are all categorised as A3 recorded wreck sites, which are historic records of possible archaeological interest where no corresponding geophysical anomaly has been identified in this phase or previous geophysical surveys.


38.


It should be noted that no sidescan sonar, magnetometer or multibeam bathymetry data beyond the immediate study area has been assessed and as such there is the potential for remains of archaeological interest to be present on the seabed beyond the East Anglia THREE survey area that are not mentioned in this report. The investigation consisted of 100% geophysical data analysis and interpretation.


1.2.2 Summary Results 39.


Below is a summary of the number and types of features identified within East Anglia THREE. The anomalies have then been divided into their classifications and described accordingly:

Furthermore, these sites of potential archaeological interest can be classified by probable type, which can further aid in assigning archaeological potential and importance:
