Department for Environment, Food and Rural Affairs (DEFRA) MCZ: Greater Haig Fras: Multibeam, Sidescan Sonar, Benthic Sampling and Photo/Video Survey ghgf_cend1012: Western Channel & Celtic Sea (05/07/2012 - 11/07/2012)
A seabed survey for the purpose of habitat identification and mapping at the Greater Haig Fras recommended Marine Conservation Zone (rMCZ) site, west of Cornwall, UK. Comprising acoustic corridors overlying a 5 km triangular grid of ground-truth sampling stations. Three nested full coverage areas in the west, centre and east of the site. Acoustic survey by multibeam (bathymetry and backscatter) and sidescan sonar (part coverage only). Ground-truth sampling by grabs and underwater cameras (video & stills images). Broadscale habitat (BSH) and habitat FOCI (Features of Conservation Interest) recorded at time of sampling and included in cruise/survey report. More in-depth interpretation to be made in a Post-Survey Site Report, following integrated assessment of acoustics and outputs from laboratory analysis of benthic samples. Central, full coverage area targeted to provide data sets against which the capabilities of AutoSub (an AUV owned by National Oceanogrephic Centre (NOC), Southampton, UK) could be tested. These data are archived with the Marine Environmental Data and Information Network (MEDIN) Data Archive Centres (DACs) including the British Geological Survey (BGS) DAC for geology and geophysics, The Archive for Marine Species and Habitats Data (DASSH) and the United Kingdom Hydrographic Office (UKHO) bathymetry DAC. The full site data package including raw is also available on request from BGS.

Sample equipment types used included: Grab: Amon or Hamon. CEFAS was contracted to undertake the survey on behalf of Department for Environment, Food and Rural Affairs. Positions in Lat/Long WGS84 collected by Differential Global Positioning System (D-GPS). Multibeam bathymetry corrected to Chart Datum. Depths recorded for benthic sampling stations were read from ship's echo sounder. The survey collected data from Kongsberg EM2040 multibeam system to derive bathymetry and backscatter products. Sidescan was Edgetech 4200. The EM2040 system was calibrated by a 'patch test' on 4th July 2012. Acoustic acquisiton software = Kongsberg SIS. Processing software = Caris HIPS. Replacement Motion Reference Unit (MRU) fitted on 13 Feb 2012. Video capture by Kongsberg undewater camera with video and stills capability. Benthic sampling by 0.1 sq m Hamon Grab fitted with video camera. Sediment samples taken for particle size analysis (PSA). Faunal samples washed over 1 mm sieve and preserved in formalin for laboratory analysis.
