Wessex Archaeology was commissioned by Xodus Group on behalf of Premier Oil E and P UK Limited to undertake an archaeological assessment of marine geophysical data for the Easington route option for the Tolmount pipeline. This was undertaken as part of an Environmental Statement prior to the Easington pipeline route installation. The report consists of an assessment of geophysical survey data comprising sub-bottom profiler, multibeam echosounder and backscatter data, sidescan sonar and marine magnetometer data sets, acquired during different stages and over a number of years. This assessment was undertaken in order to assess the presence of palaeogeographic features and seabed features of archaeological potential within the study area. The results of this assessment were then compiled with the results of the archaeological assessment of data acquired over the Dimlington route option. It is recommended that, should future geotechnical investigation be undertaken along the proposed route, any samples acquired containing material of archaeological potential, particularly those within the interpreted Pleistocene/early Holocene features, be made available for geoarchaeological assessment. If any material of possible archaeological potential is recovered during any groundwork operations it is recommended that they be reported using an appropriate protocol. This will establish whether the recovered objects are of archaeological interest and recommend appropriate mitigation measures.
