AreasStudy Area or to indicate the presence of a recorded but uncharted aircraft crash site should not be disregarded. Nonetheless, as derived finds, isolated aircraft remains should be considered as medium value receptors.
142. The assessment if geophysical data revealed 400 further anomalies of potential anthropogenic origin that cannot be definitively identified.
143. It is currently not clear whether these anomalies are archaeological based on the interpretation of geophysical data, although the precautionary approach is to assume that they are. As their nature and therefore value is unknown, the precautionary approach is to assume that they are of high value. As a result, their significance may be over assessed.
17.6 Potential Impacts
144. Impacts to archaeology and cultural heritage in an offshore context could include direct and indirect impacts and changes to historic seascape character.
145. Direct impacts, as stated in the NPS for Renewable Energy Infrastructure (EN-3) (Department of Energy and Climate Change 2011:49) encompass direct effects from the physical siting of the development. Potential direct impacts thus comprise both direct damage to archaeological deposits and material and the disturbance or destruction of relationships between deposits and material and their wider surroundings (i.e. the physical setting of an archaeological receptor). This may include material buried within sea bed deposits and / or material lying on the sea floor. Consequently, all aspects of the proposed East Anglia THREE project which cut through sea bed deposits or make contact with the sea floor have the potential to directly impact archaeological receptors. If an archaeological receptor exhibits height above the sea bed, such as a wreck or crashed aircraft, then any activity above the sea floor may also have the potential to damage or destroy a receptor.
146. Direct impacts to known archaeological receptors (see section 17.5) are not expected to occur as these receptors will be avoided (as set out in section 17.3.3). It is not possible, however, to avoid direct impacts to potential archaeological receptors (see section 17.5) as the locations of such sites are not known. The effect of unavoidable direct impacts to potential receptors would be significant, although agreed measures (see section 17.3.3) to address these impacts, if they should occur, allow such effects to be deemed acceptable.
147. Indirect impacts, as stated in the National Policy Statement for Renewable Energy Infrastructure (EN-3) (Department of Energy and Climate Change 2011:49) encompass indirect changes to the physical marine environment. Potential indirect
