Metadata: 2012 Marine Scotland Fetlar to Haroldswick benthic survey
Abstract:
Survey work was to confirm the continued presence, extent and status / condition of specified MPA search features maerl, horse mussel beds, and shallow tide-swept coarse sands with burrowing bivalves within the Fetlar to Haroldswick MPA search area, and to improve our existing knowledge-base on the wider distribution of seabed habitats to inform the progression of this proposal and completion of the MPA network in Scottish waters. Between 27th August - 5th September 2012 Heriot Watt University and SNH carried out a survey throughout the Fetlar to Haroldswick MPA search area conducting drop down video (DDV) tows, Van Veen grab sampling and in situ diver surveys (MNCR). In total 70 semi-quantitative epifaunal DDV stations were surveyed and 22 quantitative infaunal grab stations attempted (19 completed). Detailed in situ diver surveys were carried out at sites selected from the DDV and grab work to investigate maerl and horse mussel beds. Clump, core, and Particle Size Analysis (PSA) samples were taken at the diver survey sites as appropriate. In total three horse mussel beds and two maerl beds were investigated with divers.

Abstract | The abstract provides a clear and brief statement of the content of the resource. | Survey work was to confirm the continued presence, extent and status / condition of specified MPA search features maerl, horse mussel beds, and shallow tide-swept coarse sands with burrowing bivalves within the Fetlar to Haroldswick MPA search area, and to improve our existing knowledge-base on the wider distribution of seabed habitats to inform the progression of this proposal and completion of the MPA network in Scottish waters.

Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Drop down video footage was collected for 5-10 minutes at each station. A Panasonic NV-GS150 3 chip digital video camera was used within a Seapro housing held within a small frame / sled, and illuminated by twin 100 watt lamps. A 150 m umbilical cable carried the video signal to a Sony Video Walkman for real-time observations and recording. In total 69 DDV stations were recorded. The video footage was analysed in Adobe Premier Pro. The proportions of different substrate types, and the species present were recorded using either numerical abundance or SACFOR scales (Hiscock et al., 1996): i.e. the terms Superabundant, Abundant, Common, Frequent, Occasional, Rare were allocated to each species. Biotopes were allocated according to Connor et al. (2004). The presence of MPA search features was specifically noted for each tow. Where an obvious biotope change occurred during a tow the species counts were started from zero again and a secondary station label added, e.g. S1 and S1a. In these instances the length of the biotope was established using the GPS track and the area for use with the SACFOR scale calculated accordingly. A Van Veen grab was used to collect 0.1 m2 samples of seabed sediment from grab stations, grabs were attempted up to 3 times before abandoning station. A circa 150 ml subsample was taken from each grab for particle size analysis.The samples were washed through a 1 mm sieve (Figure 7). Contents of the sample retained after sieving were placed in a sample bucket with a 4% formalin solution with added borax buffer upon return to shore. Infaunal organisms were processed in the lab after the survey. Each sample was split into a light and coarse fraction, by repeated elutriation over a 0.5 mm mesh sieve. The light fraction was further divided into material retained on a 1.0 mm mesh and the smaller fraction separated. Each fraction was then examined by the petri dish-full under a dissecting microscope, individual macrofaunal specimens being extracted using forceps. The coarse fraction was also subdivided, the material retained on a 2.0 mm mesh being retained separately. This 2.0 mm fraction was examined in an enamel tray, using magnifying goggles, and the fauna extracted. The remaining coarse material was examined in the same way as the light fraction, under a dissecting microscope. All extracted fauna was identified as far as was practical, using the available literature. A voucher collection was also retained and sent to the Scottish National Museum for quality assurance and reference purposes. PSA was conducted following The National Marine Biological Analytical Quality Control Scheme (NMBAQC) Best Practice Guidance notes (Mason, 2011). In situ MNCR-style phase 2 surveys (see Hiscock et al., 1996) were carried out at five sites (three horse mussel bed sites and two maerl bed sites). A 25 m tape was laid out from a shot line. Two divers surveyed a 2 m band either side of the tape and recorded the presence and where possible, an estimate of the abundance of conspicuous biota using standard MNCR recording forms. Samples were taken of any unidentified species to examine in the laboratory. The transect band was also recorded using a hand held video camera (Cannon HF G10 in a Light and Motion housing) and still photographs were taken of the search features and associated communities using a digital stills camera (Nikon D70 digital SLR, and using the camera function on the video camera). For community analyses, at maerl bed sites divers took four replicate core samples (Figure 10), which were sieved through a 1 mm mesh screen and the remaining sample was preserved in borax-buffered 5% formalin. A 20 cm sediment core of 5 cm diameter was also taken for PSA, the processing of these samples followed the same procedure as stated previously for grab samples. At horse mussel beds, four replicate clump samples were taken and placed in 5 litre buckets as a corer was not effective on horse mussel beds. |
