North-West Irish Sea Mounds Survey (2003, 2006 and 2007). The North-West Irish Sea Mounds are a group of bedrock outcrops between Northern Ireland and Scotland. The aim was to improve understanding of the habitats and communities identified as potentially containing Annex I reef habitat according to the EC Habitats Directive and to map the bedrock outcrops to enable JNCC to assess the areas suitability for selection as a Special Area of Conservation (SAC). Data from four research cruises contributed to this project. 2007 surveys (21/01/2007-24/01/2007 and 25/02/2007) RV Corystes - drop down video and grab sample data. The first survey's video was poor quality due to poor visibility. 2006 survey (12/11/2006) RV Corystes - Grab sample data only. 2003 survey (01/06/2003-23/06/2003) RV Lough Foyle - multibeam, drop down video and grab sample data. Defra Natural Environmental Group Science Division (CRO 361) made a significant financial contribution to this work. Joint © 2007 DEFRA, JNCC and AFBI. 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-4736 and JNCC Report 410: http://jncc.defra.gov.uk/page-4493.

2007 Survey - Video camera - Kongsberg-Simrad Osprey underwater camera operated by a Simrad video control deck unit recording directly to a Sony DVD recorder. Stills camera system (Photosea 1000A 35 mm cameras and Photosea 1500S strobe) was also fitted to the sledge and operated through the Simrad video control unit. Slide film (Kodak or Fuji 200 ASA) was used. 0.1m2 day grab samples.
2006 Survey - 0.1m2 day grab samples Infauna analysis was carried out by an NMBAQC accredited contractor (ERT, Edinburgh). Only infauna retained on a 1mm sieve were identified. All species were counted and weighed for total biomass.
2003 Survey - RoxAnn survey grid (38kHz transducer; range set to 300m; save rate: 1s; track spacing: 500m).Video camera - Kongsberg-Simrad Osprey underwater camera operated by a Simrad video control deck unit recording directly to a Sony DVD recorder. Stills camera system (Photosea 1000A 35 mm cameras and Photosea 1500S strobe) was also fitted to the sledge and operated through the Simrad video control unit. Slide film (Kodak or Fuji 200 ASA) was used. 0.1m2 day grab samples. For more detailed information see the Cruise Report.
