Maritime Archaeology (MA Ltd) has been commissioned by Westermost Rough Ltd (WMR Ltd) to provide a geoarchaeological analysis of offshore sediments of possible archaeological and palaeoecological significance. This analysis aims to characterise and comment on the geoarchaeological potential of the seabed affected by Westermost Rough Offshore Wind Farm (Westermost Rough). Westermost Rough is located 8 km off the West Yorkshire coast at Tunstall, and the maritime area encompassed by the wind farm is 35 km2. The cores were collected by the geotechnical contractors Fugro, UK for geotechnical engineering purposes. The palaeoenvironmental information contained within the cores can be archaeologically important, and the study of these was undertaken in order to mitigate the impact of the project. This work is in accordance with, and is as specified in, the Archaeological Written Scheme of Investigation (WSI) (WMR Ltd, 2013). Maritime Archaeology Ltd assessed 14 borehole logs and 43 vibrocore logs provided by Fugro UK for archaeological potential. The work was conducted according to the method outlined in Offshore Geotechnical Investigations and Historic Environment Analysis: Guidance for the Renewable Energy Sector (COWRIE, 2011) and followed a staged assessment process.
