Metadata: 2015, Envision Mapping, Zone 6 - Rampion, Dropdown Video Surveys
Abstract:
The purpose of these reports and datasets is to provide information on the potential areas of Annex I reef (as defined under Annex I of the EU Habitats Directive CEC, 2007) located within Boulder Clearance Sector 1 within the Rampion Offshore Wind Farm Site and cable corridor. Previous geophysical and benthic surveys undertaken at the Rampion development area have identified areas of potential Annex I reef. The baseline survey undertaken by EMU in 2011 (EMU Ltd., 2012) highlighted potential areas of reef, however some of these were noted to be little more than areas of mixed hard substrata. Additional geophysical data collected in 2013 and 2015 as part of the pre-construction work for the site. This data was analysed by Envision Mapping in order to provide sampling station locations for a pre-construction benthic survey (required as part of the deemed Marine Licence(s) conditions of the Rampion Offshore Wind Farm Order 2014). As a result of this geophysical (sidescan sonar and multibeam bathymetry) data interpretation, drop down video (DDV) sampling stations were incorporated into the benthic sampling regime. These were placed in areas identified as potential Annex I habitat or other environmental features of potential conservation interest, and were representative throughout the area (Envision Mapping Ltd., 2015). The DDV surveys were undertaken between 19th and 25th September 2015. A Marine Licence (L/2015/00327/1) was recently issued to enable boulder clearance to take place at the site and this licence included a condition which stated that no boulder clearance could take place in areas of potential Annex I reef, as identified as mixed hard substrata in the 2011 baseline surveys (Emu Ltd., 2012). In order to ensure that the conditions of this licence were not breached and to inform where boulder clearance could take place, the DDV data obtained as part of the pre-construction benthic survey was analysed for evidence of Annex I reef in the areas of boulder clearance. It should be noted that this DDV survey was based on more recent geophysical data (2013 and 2015), hence the locations of potential Annex I reef did not align exactly to those identified from the 2011 EMU surveys.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Video and still images were reviewed, processed and analysed in accordance with national guidelines (Coggan et al., 2007., CEFAS and JNCC, in prep). The purpose of the analysis of the video/stills is to identify what broadscale habitats exist in a video record, provide semi-quantitative data on their physical and biological characteristics, to note where one substrate type changes to another and, where appropriate, to assign a Habitat of Principal Importance/Priority Habitat (formerly UK BAP Priority Habitat) and Habitats Directive Annex 1 Habitat. The video record was initially viewed rapidly in order to segment it into sections representing different substrates. At normal speed, the start and end points of each segment were logged, and each segment was subsequently subject to more detailed analysis. Brief changes in substrate type lasting less than one minute of the video record were considered as incidental patches and are not logged but recorded as part of the habitat description. The video footage was then viewed at normal or slower than normal speed, noting the physical and biological characteristics, such as substrate type, seabed character, species and life forms present. Where biota could not be identified to species (e.g. image was unclear) then a higher taxonomic category was assigned. When each video had been analysed it was possible to assign a relevant habitat classification according to â??The Marine Habitat Classification for Britain and Ireland Version 15.03â?? (http://jncc.gov.uk/marine/biotopes/hierarchy.aspx), and where appropriate a Habitat of Principal Importance/Priority Habitat (formerly UK BAP Priority Habitat) (http://jncc.defra.gov.uk/page-5718) and Habitats Directive Annex 1 Habitat (EEC, 1992) to each site. Where stony reefs were considered to occur these were assessed against a standard set of criteria (Irving, 2009) to provide information on the â??reefinessâ?? characteristics of the site. |
