Metadata: 2015 Joint Nature Conservation Committee (JNCC) and Centre for Environment, Fisheries and Aquaculture Science (Cefas) Monitoring Survey of Croker Carbonate Slabs cSAC/SCI (CEND2315)
Abstract:
The monitoring survey of the Croker Carbonate Slabs candidate Special Area of Conservation (cSAC) and Site of Community Importance (SCI) was carried out from 24 October â?? 06 November 2015. There were four key aims of the survey 1 - Revisit sample stations where MDAC has been previously subject to 13C isotope analysis or stations where its presence was suggested from seabed imagery (potential MDAC) within the site boundary. 2 - Improve our knowledge of the distribution and spatial extent of MDAC within the site. 3 - Improve our knowledge of areas adjacent to site; confirm the presence of MDAC, map the finer spatial extent and gather more detailed information on biological communities. 4 - Characterise the wider sediment areas found within the site. A variety of data types were collected during the two-week survey including multibeam echosounder bathymetry and backscatter, sidescan sonar, EK60 echosounder, deep-tow boomer, high resolution video and stills, benthic samples and water samples. In addition, a pumped METS methane sensor was fitted to the camera drop-frame. This survey also carried out methane sampling, but only the biodiversity data is archived with the DAC (DASSH).

| Abstract | The abstract provides a clear and brief statement of the content of the resource. | The monitoring survey of the Croker Carbonate Slabs candidate Special Area of Conservation (cSAC) and Site of Community Importance (SCI) was carried out from 24 October â?? 06 November 2015. There were four key aims of the survey 1 - Revisit sample stations where MDAC has been previously subject to 13C isotope analysis or stations where its presence was suggested from seabed imagery (potential MDAC) within the site boundary. 2 - Improve our knowledge of the distribution and spatial extent of MDAC within the site. 3 - Improve our knowledge of areas adjacent to site; confirm the presence of MDAC, map the finer spatial extent and gather more detailed information on biological communities. 4 - Characterise the wider sediment areas found within the site.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The following acoustic systems were used during surveying: â?¢ EK60 scientific echosounder â?¢ Multibeam echosounder (MBES) â?¢ Sidescan sonar â?¢ Boomer (Geoforce deep-towed boomer) Visual ground truthing was carried out using a drop frame equipped with laser scale, digital stills and video cameras. Video and stills acquisition were conducted following the MESH ROG. Benthic sampling was carried out using a 0.1m2 mini-Hamon grab equipped with USBL transponder for positioning. A Shipek grab was carried as backup, and a rock dredge was available in case the other grabs failed to acquire a sample of hard substrate. A pumped METS methane detector system was used to indicate variations in methane concentrations in the water, close to the seabed, during drop frame operations. Particle Size Analysis (PSA), Hamon-Grab samples and video analysis were carried out inline with the NMBAQC guidelines |
