Metadata: 2016 JNCC/CEFAS Swallow Sand MCZ monitoring survey CEND1016 RV Cefas Endeavour
Abstract:
The Joint Nature Conservation Committee (JNCC) and Centre for Environment, Fisheries and Aquaculture Science (CEFAS) carried out a survey at Swallow Sand Marine Conservation Zone (MCZ) between the 17th – 29th May 2016 on the RV Cefas Endeavour (cruise CEND1016). The aim of the Swallow Sands MCZ survey was to gather the initial dataset of a site monitoring time-series, that will contribute information on the habitats found at this site to inform habitat specific assessments. The survey focused on Type 1 monitoring of the designated broadscale habitat features of this site. The following data types were collected: multibeam (bathymetry and backscatter), mini Hamon grab samples (PSA and infauna), video (camera sledge) and still (drop camera) imagery (habitat and epifauna).
Data holder:
Joint Nature Conservation Committee, Peterborough Office

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The grab system used during the survey was a 0.1m2 mini Hamon grab. Samples were collected from anywhere within a 100m radius bullring centred on the target location. On recovery, the grab was emptied into a large plastic bin and a representative sub-sample of sediment (approx. 0.5 litres) taken for Particle Size Analysis (PSA). The sample was stored in a labelled plastic container and frozen ready for transfer to a laboratory ashore. The remaining sample was photographed and the volume of sediment measured and recorded. Benthic fauna were collected by washing the sample with seawater over a 1mm sieve. The retained >1mm fraction was transferred to a labelled container and preserved in buffered 4 % formaldehyde for later analysis ashore. For each grab, a preliminary visual assessment of sediment type was performed on board the vessel and noted on the field records. PSA methodology: Subsample removed and laser diffraction completed on <1mm fraction. The rest of the sample was split at 1mm and the >1mm dry sieved at 0.5 intervals. The <1mm is dried and weighed and used to calculate proportion of <1mm:>1mm.Sieve and laser data are merged to produce a complete Particle Size (PS) distribution at 0.5 intervals. The sediment samples were processed following the PSA methodology recommended by the National Marine Biological Analytical Quality Control (NMBAQC) Scheme: Mason, C. 2016. NMBAQC's Best Practice Guidance. Particle Size Analysis (PSA) for Supporting Biological Analysis. National Marine Biological AQC Coordinating Committee, 77pp, First published 2011, updated January 2016. Infaunal QC protocol: NMBAQC Own Sample procedure used. The sledge was fitted with an STR Seaspyder Telemetry (Canon EOS) 18 megapixel digital stills camera with quartz corrected dome lens and STR MP-F through-the-lens-controlled flash. It was controlled through a dual role copper/fibre multiplexor custom built to Cefas specification. The video footage was shot using an STR SP-IPC-3000a 1080p video camera with a 0.1 Lux colour 5 megapixel sensor. Illumination was provided by four to six STR MP-3 LED lights running at 1500 Lumens light intensity per unit. Laser scaling was provided by two green dot class 3r laser pointers providing a reference width of 21cm on the seabed. The sledge was also fitted with a digital heading/pitch/roll sensor, altimeter and water temperature sensor. This was recorded in real time along with GPS time and position using a video overlay. Set-up and operation followed the MESH ‘Recommended Operating Guidelines (ROG) for underwater video and photographic imaging techniques’ (Coggan et al. 2007). The digital stream was captured by a surface PC and recorded direct to MP4 format video files. The stills camera fitted to the drop frame was an STR Seaspyder Telemetry (Canon EOS) 18 megapixel digital stills camera with flat lens and STR MP-F through-the-lens-controlled flash. It was controlled through a dual role copper/fibre multiplexor custom built to Cefas specification. The video footage was shot using an STR SP-HDC-3000aw 1080p video camera with a 1 Lux colour 2 megapixel sensor. It was run at 1080p (25 frames per second) video resolution along with all other control signals over a dual fibre optic cable. The digital stream was captured by the surface PC and recorded direct to MP4 format video files. Lighting was provided by four STR MP-3 LED lights running at 1500 Lumens light intensity per unit. Laser scaling was provided by two green dot class 3r laser pointers providing a reference width of 21cm on the seabed. The drop frame was also fitted with a digital heading/pitch/roll sensor, altimeter and water temperature sensor. This was recorded in real time along with GPS time and position using a video overlay. Set-up and operation followed the MESH ‘Recommended Operating Guidelines (ROG) for underwater video and photographic imaging techniques’ (Coggan et al. 2007). Field notes were made during each camera deployment, noting station and sample metadata, real-time observations of substrate and taxa, and an initial assessment of the range BSHs that had been seen MBES bathymetry and backscatter data were acquired using the Kongsberg EM2040 system operated at 300kHz and deployed on the drop keel of RV Cefas Endeavour, which was lowered to its full extent to minimise the effect of bad weather on the acoustic signal. Variations of sound velocity with water depth were determined using a Conductivity Temperature Depth (CTD) probe and applied during MBES data acquisition. The raw MBES bathymetry data was processed using CARIS HIPS. Tidal information was gathered using a CNAV 3050 DGPS receiver. Tide height data was smoothed and extracted to reduce the tide on the bathymetry. The soundings were cleaned and smoothed using CARIS in accordance with the International Hydrographic Organisation (IHO) Standards for Hydrographic Surveys - Order 1 (IHO 2008). MBES backscatter data were processed with Fledermaus Geocoder Toolbox (GT) to produce standard and floating point (FP) geotiffs. |
