Mid Irish Sea reefs Survey (2006-2007). The aim of this survey was to improve understanding of the habitats and communities present in an area of the Irish Sea identified as potentially containing Annex I reef habitat according to the Habitats Directive. Survey cruises were undertaken in November 2006 (Multibeam), January 2007 (Sampling) and March 2007 (Sampling) onboard Research Vessel Aora, with specialists from the National Oceanography Centre (NOC), ERT (Scotland) Ltd (ERT), University Marine Biological Station and Seatronics Ltd. Data collected included multibeam, drop down video and stills camera images. Defra Natural Environmental Group Science Division (CRO 361) made a significant financial contribution to this work. Joint © 2006 Defra, JNCC and ERT (Scotland) Ltd. The geology component of the data is archived at the British Geological Survey (BGS) MEDIN Data Archive Centre (DAC) for Geology and Geophysics. Biological and bathymetry data are archived at DASSH and UKHO respectively. For more information see http://jncc.defra.gov.uk/page-4735, JNCC Report 411: http://jncc.defra.gov.uk/page-4518.

The camera system used was the Seatronics DTS6000 deployed from the RV Aora. The camera system included a Konsberg Simrad OE14-208 Digital Stills Camera System (5 Megapixel) and Kongsberg OE14266/1366MK2 Colour Video Camera (460 TVL) with four 35 W HID lights. For accurate camera positioning fixing the system used a Sonardyne Scout USBL.
Camera drops of up to 10 to 15 minutes were recorded to collect information on the main substrata and to identify conspicuous epifauna and assess abundance across the northern area of the AoS. Digital still photographs were taken at 1 minute intervals at each station to show ground type and additional photographs were taken of conspicuous epifauna/rocky substrata. For more detailed information see the Cruise Report.
