This was supported by a preliminary review of acoustic data and assessment for the presence of Annex I reefs to minimise the risk of potential damage to protected features. Following the review of existing data, a drop down video survey protocol was developed (EMU, 2011) and approved by the Marine Management Organisation (MMO). Part of this protocol identified that a number of proposed geotechnical sampling sites were likely to be in the vicinity of potential Annex I reefs and therefore warranted field ground-truthing by means of drop down video to verify the presence and status of these features. The video ground-truthing survey has now been completed. Drawing upon the findings of this survey, the 2012 EMU report present within this series provides an update of the assessment of the potential Annex I reefs present at the proposed geotechnical sample locations and fulfils condition 3.1.1 of the Marine Licence (Licence L/2011/001075). The aim of the 2013 Fugro EMU document also present within this series was to satisfy Marine Licence condition 31.22 and to address the responses from the MMO regarding the Annex I reef features (letter ref: REN024, dated 12th April 2013, and 21st June 2013). The objectives were to assess the impacts (direct and indirect) of the construction activities on the potential Annex I features. The objectives of this report were to: - Assess the direct impact (loss of habitat) of each of the construction activities; - Assess the associated indirect impacts (increase in sediment smothering, and suspended sediment concentrations); and - Assess the cumulative impacts of all construction activities.

The preferred geotechnical sampling point was investigated initially, with full video coverage and at least 5 stills images collected along a 100m transect in the direction of the feature, to confirm extent or proximity of the habitat If no features of interest were found then an additional transect was surveyed perpendicular to the original transect to confirm habitat extent. This maximised the potential to use the information derived from the geophysical data, rather than employing a simple four point (cardinal) survey. Figure 2.1 illustrates the sampling protocol adopted.
