Wessex Archaeology (WA) was commissioned in 2012 by E.ON Climate & Renewables UK, Humber Wind Ltd. to process and interpret geophysical data acquired over the Humber Gateway Offshore Wind Farm and export cable route. The Humber Gateway Offshore Wind Farm is approximately 8km east of Holderness on the East Yorkshire coast. The geophysical data were acquired in 2012 by Osiris Projects and WA was required to assess the sidescan sonar and magnetometer datasets. Following alterations to the inter-array cable routes more survey data were acquired in 2013, which WA was also required to assess. Wessex Archaeology has been involved in a number of phases for the Humber Gateway development since 2005 including several archaeological geophysical assessments, Written Schemes of Investigation, Desk-Based Assessments and an Environmental Impact Assessment. In order to set the background and context for the assessment of the 2012 and 2013 geophysical data, this document presents a summary of earlier geophysical assessments and the resulting interpretations, Exclusion Zones and buffer zones. Nine Exclusion Zones and three buffer zones remain in place from earlier assessments by Wessex Archaeology. The assessment of the 2012 to 2013 datasets resulted in a total of 2217 features of potential archaeological interest over both the wind farm and the export cable route corridor. The recommended mitigation is that all features should be noted during development and construction activities and impacts on them should be avoided where possible. If impacts cannot be avoided then any finds that may be of an archaeological nature should be reported through the Offshore Renewables Protocol for Archaeological Discoveries. In addition, a selection of features resulting from the assessment should be dived in order to aid the archaeological characterisation of the development area. The geophysical report is given in Volume 1 and the gazetteers of geophysical anomalies of potential archaeological interest are given in Volume 2.
