This assessment included interpretation of sidescan sonar, magnetic and multibeam bathymetry datasets covering the proposed Gwynt y Môr offshore wind farm off the north coast of Wales. This report outlines methods used for data acquisition and interpretation in conjunction with the results of the archaeological assessment of the geophysical datasets. The study area covered by this assessment includes the east and west inter-array cable routes and also the export cable route. A total of 109 anomalies were identified during the course of the archaeological assessment, although these tended to be small and of uncertain origin. Limited mitigation in the form of ongoing monitoring during construction is advised rather than exclusion zones.

Sidescan sonar, multibeam bathymetry and marine magnetometer datasets were processed for archaeology. The geophysical data were assessed for quality and were generally rated as ‘Good’ using the following criteria: Data which are clear and unaffected by weather conditions or sea state. The dataset is suitable for the interpretation of standing and partially buried metal wrecks and their character and associated debris field. These data also provide the highest chance of identifying wooden wrecks and debris.
